Precision EDM copying-broaching system

DGT-EP-03

We are happy to introduce our new product  - a desktop precision EDM copying-broaching system DGТ-EP-03.

Desktop EDM broaching system DGТ EP-03 is designed for making through and blind holes of any shape in electrically conductive materials. This system can be used as a copying-broaching machine for manufacturing small dies, stamps, etc.
The system is equipped with control device and technological current generator allowing to execute high-speed and high-accuracy machining of your parts. In contract to the other similar equipment DGТ EP-03 runs on tap water. You can also use deionized water in order to reduce electrode wear.
The system can be operated from computer or manual console.

Up-to-date technological current generator allows to broach holes with fine wire (d 0.15 mm) or foil paper with thickness from  0.05 mm.
Machine software allows to execute automatic processing of standard parts. Automatic approaching function (surface searching) and program start with one touch of the button is also available.

In full system specifications become apparent in jeweler industry (stamp manufacturing and finished products stamping), electronic industry (broaching holes with diameter from 0,1 mm in hard-to-cut materials such as carbide material, hardened steel, etc.), defectoscopy (sample making), metal-working (removal of broken taps) and many other industries.

Due to its small size and low price the machine DGТ EP-03 can be used in educational process.

Besides this broaching head of the machine DGТ EP-03 can be installed on two-axis table and the system can be used for spark erosion with the help of 3D CNC system DGT-735-5.
