EDM Drilling Machine

EDM Drilling Machine

An EDM drilling machine does not require physical force to drill. The drill can drill through any material without wearing out the drill bits, and it can drill high-hardness materials. Unlike mechanical drills, an EDM drilling machine can drill through pre-hardened parts without sacrificing accuracy or speed. A pair of automated electrode-changing stations allows the machine to operate continuously for long periods of time. The drilling machine can make one hole every 90 seconds, and can process several hundred sheets of steel.

The Current Model RT6050-5AT EDM drilling machine from Methods Machine Tools has a multi-axis Siemens 840D CNC controller to offer greater expandability and security. Its latest software and hardware upgrade will help improve drilling speed, stability, and decrease electrode usage. The machine also features a traveling bridge X-axis, and can accept multiple sizes of rotary tables. Its EDM drills a hole in a metal surface in 300 mm increments.

A high-quality EDM drilling machine has a powerful, intelligent power generator. Its Intelligent Power Generation (IPG) generator will provide precise spark control to the machine for accurate drilling. It has different parameters for electrode location and stage. This feature can decrease electrode wear while enabling higher drilling speed and surface quality. A wire EDM drill requires a highly skilled operator to achieve a high-quality finish. EDM drilling machines with digital generator technology will provide faster, more consistent results with lower electrode wear.

The electrodes used for EDM operations are made of copper, brass, or nickel. While brass electrodes are more machine-friendly, they are not recommended for wire-cut operations. This is because brass electrodes can lead to "brass on brass" wire breakage. Therefore, copper is the preferred electrode for wire-cut operations. These are only a few of the reasons why the EDM process is preferred. The benefits of this process are numerous.

A high-quality EDM drilling machine can process a variety of workpieces. In many cases, the EDM drilling machine can process a multihole workpiece in just a few minutes. This is important for high-volume production because the machine needs to cut as many holes as possible while decreasing electrode wear. In addition, an EDM drilling machine will not cause 'bullet nosing', which is an unpleasant side effect of conventional hole popper drilling.

Another feature of an EDM drilling machine is its ability to drill through most materials. Hard metals, such as steel, are notoriously difficult to drill through. Conventional drills can also break if the torque is not controlled properly. A broken drill is difficult to remove from a workpiece, and it costs a great deal of time to replace. Worse, a broken drill can ruin a perfectly good part. In contrast, EDM drilling creates no burrs and is much faster.

EDM drilling has many applications. In machining turbine blades, EDM hole drilling is used to drill rows of small holes. These holes allow gas to flow through the turbine blades. This allows for the use of high temperatures and crystals. Conventional machining of high-aspect ratio turbine blades is a difficult task. A high-end machine can use both metals and plastics. With an EDM drilling machine, you will not have to worry about cutting metals in the middle of a turbine blade.
