EDMs, or electronic discharge machines, are computer controlled machine tools that use electrical discharges or sparks to create a desired shape in a metal. An EDM machine may be interchangeably called spark machinery, die sinking, spark eroding or wire erosion since metals are subjected to different electrical process to obtain the desired design or shape.

There are two main types of electronic discharge machines.

A sinker EDM which uses an insulating liquid (oil or dielectric fluid) to apply electrical discharges and a wire EDM that uses a single strand of brass wire to make deep cuts in the metal. Other popular types include small hole and spark EDM’s.

There is a very long list of industries that use these machine tools. From manufacturing coins to fabrication of vehicle parts, these industries and more have benefited from the precision and effectiveness of various EDM machines. In mould production or the creation of prototypes of any machinery component, they are indispensable as a mould-making tool. Countless industries like automotive, electronics, mechanical and aerospace industries have used parts and components that are produced using these machines.

EDMs are also used in processes requiring precise and accurate cutting or forming. A small hole drilling EDM is used to create holes in metal parts so that large plats may be eroded to the metal without the need of pre-drilling. This method is used in many industries to create parts such as turbine blades in jet engines, different components for fuel systems, and many more.

Why are EDMs preferred over other computer controlled cutting machines?

• These machine tools are able to cut hard metals according to any set design which may not be possible using other kinds of traditional cutting tools. They can shape extremely hard metals which are impossible with many other cutting tools and equipment.
• They are designed to create high quality, precision finished products. Problems with final product outcome are eliminated since there is no point of contact in between the tool and the metal or work piece.
• The end result is a metal part with a good surface finish due to the critical cutting
  ability of the tool. Even fine holes are possible with an EDM which is impossible to recreate using any standard cutting tool.
• The production speed may be slower when compared to high volume production cutting tools but the finished product is as good as the prototype.
• The use of oil-based insulating fluid improves the way the material is cut. This ensures precision and impressive end results which can reduce material costs.

Although the most common disadvantage of excessive wearing of tool parts is inevitable in most EDMs, parts and precision components are typically easy to locate.

There are also many companies that provide maintenance and repair services. These machines do typically require a great deal of maintenance and efficient handling.

However, well-maintained units will provide years of precision service.

An EDM machine is indispensable no matter what industry it is used in, so be sure that you trust only the most reliable EDM distributors in your industry for equipment, parts, and service.

When medical computer carts were first designed for and marketed to hospitals several years ago, many administrators realized the potential of this technology to streamline workflow and record keeping. They also expected that this efficiency would translate to improved patient care and safety. They were right. Mobile computer carts give nursing staff the ability to document medical history and other information from the patient’s bedside shortly after admission. More recently, features such as bar code readers have been added to medication carts. This technology makes dispensing medication and record keeping faster and it reduces the chance of human error.

This type of medical equipment has been around long enough for health care professionals to recognize their potential and their limitations. The present generation of medical equipment has been designed to address the needs and desires of health care professionals. Here is a short list of some of the recent developments in medical computer cart.

Ergonomics
One medical computer cart may be used by people of widely varying heights throughout the workday. Some staff may prefer working from a seated position while others are happy standing. A portable workstation that can change height quickly and easily is ideal for these situations. Adjustable tilt keyboards allow for optimal ergonomics as well.

Power Supply
The advantage of mobility doesn’t count for much if a systems portable power source is inadequate or unreliable. A portable power source should supply enough Watt-hours to operate a portable computer for several hours. Ideally a portable power source should clearly indicate when it is running low. Having the choice of AC or DC recharging is an added bonus. There are, of course, tasks and situations where a robust portable power source is unnecessary. Features like a hospital grade cord reel for the AC power supply are a great convenience in these cases.

Security
For many hospital computing tasks, basic laptops are the most cost effective computer for use with medical computer carts. Unfortunately, laptops are a popular target for thieves. Every 53 seconds someone somewhere has their laptop stolen. In a hospital environment, it’s especially important to guard against theft because computers are likely to contain confidential patient records. Many medical computer carts are designed with rugged physical security that essentially eliminates crimes of opportunity. Carts that house a CPU instead of a laptop can also include high security fasteners.

These are just some of the features that have been developed for medical computer carts. Healthcare is an evolving industry and you can expect mobile medical computer carts to evolve as well.
