Modern production schedules require machines that can manufacture and finish parts at a rapid pace and also with a very high level of consistency. The humble lathe machine that at one time was purely mechanical has now morphed into modern CNC lathe with a very high degree of automation and accuracy.

Uses of CNC lathes

CNC lathes are usually used on metal components that require some material to be cut out through turning. They are also used to drill multiple holes including centered holes usually in blocks of metal. However, modern CNC lathes are also used on other materials including plastic and wood. Lathe machines are widely used for making cylindrical parts such as gears, crankshafts, etc which require a very high level of accuracy as manufacturers compete to produce engines and gearboxes that are more silent and efficient than their adversaries. Manual lathes such as the turret lathes, engine lathes and special purpose lathes were previously used but with a rise in production levels automated CNC lathes offer higher production output with fewer errors, while the manual ones are still used by smaller workshops.

Modern types of these machines can make short work of a job-work

Modern types of these machines are a combination of a computer with a lathe machine and a controller that converts each digital signal into the desired action. Specialized software is first used to create the required design that needs to be replicated physically on metal, wood, etc. Next, the job-work, work or work-piece is fitted on the chuck and rotated at slow or high speeds depending on the material and the type of cut or centering required. The program instructs the lathe machine on the type of cutting, drilling or centering required including the depth and width. While older lathe machines could only do cutting functions, newer machines can do cutting and milling and the high end ones can even have four spindles to perform multiple jobs simultaneously, thereby reducing operations and improving productivity.

The latest CNC lathes require an operator to oversee the mechanical process, which in the past would have required one or two operators for actual physical work. A programmer is also required to compile the software commands needed to instruct the machine to provide precise cuts or holes. The tool bits that are required to cut through steel are usually made of titanium carbide, tungsten carbide, etc depending on the material that needs to be cut. The tool bits are used until the tolerance levels are maintained after which they are either sharpened, if possible, or simply replaced with a new bit.

Advantages of using CNC lathes

The advantage of using CNC lathes is that it offers a very high level of accuracy in drilling, cutting, milling, etc while also maintaining optimum production speed. With the advent of computers, the risk of physical injury to the operator is also reduced while the software offers manufacturers a chance to give shape to products that would not be possible if manufactured by hand. While small and medium sized CNC lathes are used by workshops to craft products that might have gone out of production a long time ago, such as parts for antique cars or even for older machines, larger lathes are usually used on the production line to manufacture parts in large quantities.

The advent of newer technologies has turned the humble lathe machine into CNC lathes capable of converting any creative thought into a real shape. Various models and sizes are used for specific purposes and CNC lathes do not need to be taught the entire process every time a new tool is attached thus saving time, effort and money while offering safety, efficiency and accuracy.

One of the truest sayings is that “variety is the spice of life”. For centuries people have thrived off of being different and adding new and exciting twists to daily routines. Changing something around or switching things up can often be just what is needed when our motions are becoming unbearably mundane. Creativity and innovation require it. Change is something that is inexplicably unavoidable if humans expect to advance in any way shape or form.

If we really think about it, transformation is an unstoppable force that is rarely dodged even by the most stoic. Mimicking and complying with nature’s powers, the conveyor industry has had to adapt to change’s desires as well. Due to growing needs and highly realizable values, conveyor types have risen drastically in numbers. After exploring all of the current conveyor types available and what they may be used for, the picture may become clearer on how much the conveyor has truly evolved.

Conveyors in some form or fashion are used in almost every large multi-faceted business environment. Many of the common items we use everyday at one point or another spent a portion of there production lives on a conveyor. Some of the more standard types of conveyors include gravity conveyors, belt driven conveyors, line roller conveyors, accumulation conveyors, line shaft conveyors and chain motored conveyors. These conveyor types are mostly the traditional rectangular flat based object movers we are accustomed to seeing in the movies or maybe on a factory tour.

Responsibilities for these types of conveyors are mostly simple tasks that involve moving non-sensitive packages in straight lines. Although there is great variety throughout these conveyor selection types when we get into and look at the more customized and specialized conveyors we can truly get a feeling for the wide range of market options.

As minds think more outside the box and economic and exploratory needs demand it, conveyor types are slowly becoming more robust and unique. Conveyor types such as low profile belt conveyors, bulk processors, matt tops, sorters, truck loaders, mobile conveyors, adjustable conveyors, pallet handlers, spiral and funnel conveyors, and glass cullet handlers are all examples of next generation machines pushing the boundaries of productivity and mutability.

It is in these types of conveyors that we really begin to see the true breadth and depth of choice. As these different varieties take on new methods, objects are now able to be moved and handled in previously unthinkable ways. No matter what happens through all the twists, turns, spirals, spins, climbs, dumps, pours and other tasks given to the new wave of conveyors, one thing is for certain; that variety and change will forever exist in the world of manufacturing.

If we are looking for examples of production variety within businesses, conveyor might be a great choice. As they become more and more commonly used by large corporations we should see the number of available types and variations become even greater. Conveyors are an amazing mechanical invention and the sheer volume of different conveyor types is a true testament to how relied upon and utilized they have become in today’s society.

Any band saw can resaw. The question is: “How well and how thick?” The first thing you need to decide if resawing on your band saw is an activity in which you are likely to engage frequently, occasionally or never. For those of you who don’t know, resawing is the ability to cut thin slices or veneers out of a board standing on its edge on the band saw table, while being guided along a high fence. Where this pays off is when you are trying to get maximum mileage out of an especially fine, beautiful, expensive hardwood board.

For example, I made a lot of jewelry boxes with 3/8″ thick sides. Considering that I had to sand all of the sides flat and smooth, I found that I could barely get 2 slices out of a 1″ thick board or 3 slices out of a 1 1/2″ board or 4 slices out of a 2″ thick board. You need to allow 1/16″ kerf waste for most band saw blades plus more if your blade wanders, which all blades do to a certain extent. Then all unevenness has to be sanded away in a drum sander or wide belt sander. In the end, you can’t realistically expect to get two finished 3/8″ box sides out of a board that is only 3/8″+3/8″ +1/6″ = 13/16″ thick. You will need not much less than a full 1″ thickness in your original board. Since most hardwood lumber is sold milled down to 7/8″ for a so-called 1″ board, you are faced with only getting one, 3/8″ slice, not two. On the other hand, most 2″ lumber comes milled down to 1 7/8″, which allows you to bet three 3/8″ pieces out, saving you money.

The more your band saw blade wanders, the more thickness you will need. The important thing is to minimize this wandering and there are five ways to do this: (1) blade tension (maximum recommended to keep the blade from flexing), (2) blade width (the wider, the better for stiffness), (3) blade type (designed specifically for resawing), (4) motor power (to drive the blade through the wood without bogging down) and (5) blade guides (the more blade control, the better).

If you plan on doing a lot of resawing, pay close attention to the specifications of band saws you are considering for purchase, in light of what has been said above. If resawing doesn’t look like it will play a large part in your future, then you are probably more interested in cutting curves in thinner material. In this case, throat depth of your band saw becomes a very important consideration because, on a small band saw, you will be constantly bumping into the back of the throat and you may not be able to complete the curved cuts you have penciled out.

Any 14-inch band saw will severely limit the width of cuts you can make to the left of the blade, so consider if this will present a problem for you. If you are planning on just cutting out small parts, fine. On the other hand, if you want to make large parts for furniture, then a small band saw just won’t do. Of course, there is no limitation to the right of the blade, on a 14″ (or any other) band saw, except that you will have to supply auxiliary support for your work piece if it extends very far off the edge of the table. Throat depth is not so much of a problem when you are using the band saw for resawing, although, for resawing, you will need to consider the maximum distance between the table top and the upper blade guide. That measurement determines how wide a board you can resaw on your band saw.

When shopping for a band saw, don’t be fooled into thinking that an 18″ band saw will give you a full 18″ between the blade and the back of the throat. Band saws are measured by the outside diameter of their wheels. These wheels are mounted inside the cabinet, one above the table and the other, below. Actually, there is an upper cabinet and a lower cabinet connected by a “column”. The blade travels upwards from the lower (powered) wheel through and inside the column to the upper (idler) wheel before reversing direction and going downwards through the upper blade guide, then the table, then the lower blade guide before returning to the lower wheel.

Because the column takes up a certain amount of space, an 18″ band saw will not normally have a full 18″ throat. It will be something less than that, perhaps 17½” (if you are lucky) or even 17″. So, if you need a full 18″ of clearance, you will need a 20″ band saw. Prices climb with throat depth simply because as throat depth increases, the wheels and the cabinets must increase in size accordingly. In short, the whole machine gets bigger.

Small band saws with small wheels may not be tall enough to sit on the floor like larger ones. With small band saws, you must either mount them on a bench or purchase or build a stand. Usually the stand is included in the price of the smaller saws. Conversely, when working on a very large, industrial band saw, count on the table top being quite high off the floor to accommodate the lower wheel and its cabinet.

When you order blades for your band saw, do so in quantity. There are few sure things in life but blade breakage is guaranteed. Always have replacement band saw blades on hand so you don’t end up breaking your only blade right in the middle of a project. When you do order blades, you can usually find the best prices online but you will need to allow for delivery time and shipping costs. You can buy blades from the saw manufacturer but it is usually cheaper to purchase them from a vendor who specializes in band saw blades. If you can’t find the exact size your band saw uses, you can ordinarily have your blades custom-welded to any length you need.

There are times when you want a specialized band saw blade for a specific use like resawing. Here, the challenge is to get a reasonably smooth cut but not to have so many teeth that it causes an undue amount of friction, heat and wandering. In a case like that, it may be best to buy directly from the manufacturer of your band saw. Band saw blades designed to cut tight curves are as narrow as 1/8″. For most curves, I have found 1/4″ blades to be sufficiently narrow. The narrower the blade, the more likely it will be to break quickly but it can track tighter curves than wider blades. For really tight curves, a scroll saw may be a better tool than a band saw. Resaw blades should always be as wide as your band saw can accommodate.

There are two basic types of blade guides on band saws: “blocks” and “ball bearing guides”. Blocks can be made out of smooth metal, non-metallic composite or ceramic material. Ball bearing guides are more expensive but are much easier on blades in that there is minimal friction and, therefore, reduced heat. There are side guides in any band saw to restrain the blade from moving left or right and a single block or bearing behind the band saw blade to keep it from moving backward when pressure is applied to the front of the blade by the work piece. After-market ball bearing guides with full installation instructions can be obtained from manufacturers such as Carter. The more expensive band saws come already equipped with ball bearing guides.

Like other stationary power tools, very large band saws usually have three phase motors. You should not consider purchasing one of these unless you have three phase power available at the place where you will be using the saw. Three phase power is usually only available from the power company in commercial or industrial areas and cannot be found in residential areas. The only way to have three phase power in a home woodworking shop is to use a phase converter that is large enough for the power requirement of your largest three phase motor. If you plan on running more than one three phase motor at a time, you will need a correspondingly larger phase converter. There are two types of phase converters: rotary (looks like a big electric motor) and electronic. Rotary is better if you can find it. Search for phase converters online.

A two speed band saw is useful if you are planning on cutting metal or very dense hardwoods. Running the band saw on the slow setting will mean that while it will take longer to make cuts, it will reduce heat from friction and extend blade life. Metal cutting band saw blades are widely available for cutting mild steel and non-ferrous metals. Never use a metal cutting band saw blade to cut wood. Never use a wood-cutting band saw blade to cut metal.

Some band saw wheels are bare metal. If you want to track narrow blades, your band saw wheels should have rubber “tires” that are glued onto or inserted into grooves in the metal band saw wheels. These tires are usually crowned. By adjusting the blade tracking device, you can get the blade to stay in one position on the tires or metal wheels.

Another adjustment moves the upper band saw wheel up and down to increase or decrease blade tension. You will need to release this tension to change band saw blades and, on the newer band saws, you can usually find a lever that does this for you. If not, you will have to loosen the tension knob enough to install a new blade on the wheels. Then re-apply the tension, using the blade tension scale, appropriate to the blade width you are using. Wide blades will require more tension than narrow blades. Narrow blades can break if too much tension is applied. Large band saw blades can wander off the band saw wheels if insufficient tension is used. Always refer to the tension scale on your band saw. Don’t guess.

After the band saw blade is tensioned properly, disconnect power to the motor and turn the upper wheel by hand to verify that the band saw blade is tracking properly. If not, make appropriate tilt adjustments to the upper wheel until the band saw blade stays in the approximate center of both wheels. A hand wheel or knob is provided on any band saw for this purpose. If the wheels are slightly out of alignment with respect to each other, you can still track a band saw blade. In this case, the band saw blade will be more to the back of one wheel while being more to the front of the other wheel. This discrepancy should eventually be adjusted or “tuned” out of your band saw, but, for now, it’s OK as long as the band saw blade stays on the wheels while cutting. Once you have the band saw blade tracking properly, reconnect the power and start cutting.

Baling presses are designed to condense waste and save space before your rubbish is collected. Baling equipment compacts paper, cardboard and plastic. Separating waste is important to industries that produce a high throughput of waste and rubbish collection companies alike.

Waste disposal can be a concern for industries. In the UK businesses are expected to segregate their rubbish and aggregate it for more efficient disposal. Specialist baling machinery is available to carry out this task in the most cost effective and time efficient way possible.

Many different types of baling presses are available from horizontal to vertical, and mini to midi.  Each having their own advantages and disadvantages.

Horizontal Balers

Fantastic for high throughput waste baling.  Semi or fully automatic in operation thus requiring less manual operation.

Vertical Balers

Designed for lower throughput than the horizontal baler but is more labor intensive due to its manual operation.

Mini and Midi Balers

Can be used indoors or outdoors. Versatile and produces manageable bales that don’t necessarily require specialist machinery to transport them. This type of baling machinery is ideal for producing small bales.

Your choice of baling press must be made based upon your requirements.  Consider whether your waste throughput will change in the future and plan accordingly. Baling presses can be purchased or leased. Which is better for you or your organization depends on your particular requirements.  For example, many industries that need to free up more operators choose horizontal balers because they can be semi or fully automated. If space or bale size is an issue then a mini baler may be more suitable.

When sourcing a new press brake the buyer’s goal should be to match the equipment to their expected requirements and use, plus get the best value for their investment. This means obtaining an excellent quality product with proper features at an affordable cost. Also, just looking at initial cost can sometime be deceiving as life cycle costs should be accounted for that includes maintenance costs and efficiency of labor in using the press brake.

Hydraulic press brakes began replacing mechanical ones in the ’70s due to costs and safety issues. Mechanical components were replaced with a hydraulic system which eliminated these costly machined parts. Of course, incorporating a superior hydraulic system with quality components is paramount to supplying reliable and accurate equipment for the end user. The buyer should also ask if valves, rings, seals and other key hydraulic components are readily available and if the company they are buying from has a good after sales service staff. Proprietary parts are often difficult to find or can take a while to obtain.

Press brakes, like all machines, have features that differ across the various manufacturers. The back gauge is a feature that is generally not included with this machine as standard equipment even though it is extremely useful. This gauge is typically sold as an option. This is true also for tooling as well. There are specialty tooling companies that sell after market press brake tooling for all types of press brake jobs. Yet, a savvy buyer will be able to negotiate a front operated power back gauge and tooling package to be included with their press brake purchase. If the supplier is on the cutting edge he will have either American or European style tooling to offer to the customer.

Since the buyer usually has to rely on the salesman’s recommendations, it is very important to buy from a dealer who not only is knowledgeable about metal fabricating machinery, but also has some metallurgical background and common sense. When the customer says they want a 150 ton press brake for instance, the salesman needs to query them further and pin point the type of material they are going to be working with. Bending stainless steel requires 50% more power than bending 60,000 tensile plate for instance. The salesman should know that the term “mild steel” hasn’t existed in over 20 years. This material was replaced with A36 and the tensile can range from 57,000 psi up to 80,000 psi. There is a huge gap, so instead of figuring 15.4 tons per foot when bending ¼” A36 material you need to kick it up to at least 19 tons per foot. Even though the end user may not have given enough information to the sales person, it is still up to the sales person to help match up the right equipment for the job by asking the right additional questions.

The buyer also needs to be certain that whichever press brake they purchases that it is flush floor mounted. Many of the 150 and 176 ton machines on the market require a slot in the floor to accommodate the apron that hangs from the front end of the press brake. Sometimes the photo in a catalogue does not pick up this issue. Ask your sales person so that you don’t become surprised and pay a lot more money for this type of foundation.

Purchasing press brakes is an important task; there are some valuable tips that can go a long way in saving the buyer money and labor. Be sure to do your research and search for high quality equipment, as witnessed by this salesman.

In industrial context, welding refers to a fabrication process that joins materials such as metals and thermoplastics, by causing coalescence. This is typically done by softening the work pieces and adding a filler material, which is often a welding rod, to form a pool of molten material that cools to become a strong joint. Various processes and energy sources are used for welding, such as gas flame, electric arc, laser, electric beam, friction, and ultra sound.

Welding machines can be broadly classified into different categories depending on the type of welding processes and equipment used during the process. Some welding machines use transformers for converting high voltage, low current electricity into high current low voltage, often between 17 to 45 volts and 190 to 590 amperes. These types of welding machines are the least expensive and allow welders to select the output current by either moving the core of the transformer in and out of the magnetic field or by allowing the welder to select from a set of taps on the transformer.

Some welding machines use an internal combustion engine or an electric motor to drive the alternator or generator present in these machines. The process used is similar to transformer based welding machines as power is first converted into mechanical and back to electrical energy to achieve the step-down affect.

Inverter based welding machines use high-power semiconductors such as the IGBT for building a switching power supply capable of handling high loads of arc welding. These machines convert utility electricity into high voltage and store it in a capacitor bank. The stored energy is then transferred to a secondary transformer for producing the desired welding current.

Welding machines have simplified different types of machining jobs undertaken in small and large manufacturing companies. Automated welding machine is also in use and has helped in increasing the effectiveness of welding processes.
