ED CNC EDM construction


  • Exclusive Excetek computer CPU system. The company conducts its own research into the development of more advanced program management systems. Expanded functionality and improved control of all EDM processes, increased productivity and advanced automation features.
  • Possibility to adjust functions according to different requirements to shorten the processing time and increase its quality.
  • In addition, when using the processing (modes) embedded in the CPU database, the necessary parameters can be set from the databases of the users themselves.
  • Standard G-codes in ISO format. Ease of use, compatibility.

Superior Spark Discharge Functions

EXCETEK EDM is built with MOSFET sparking circuits that provides less electrode wear and fast spark-erosion machining speed as well as achieving smooth surface roughness with finishing conditions.

Stable Generator Performance

Front and back have separate double heat flow systems in which hot components and cold circuits with electronic components are separated. This provides adequate heat sinking and cooling to improve generator stable operation with nearly zero maintenance.

Simple Maintenance

EXCETEK generator uses front and back assembly module design where the function of circuit indicates clear at each circuit which have fuse protection. This helps more easier for maintenance to check and (if necessity comes) exchange a PCB. This facilitates the maintenance and provides user friendly service for the customers and service maintenance personnel.

EXCETEK and EXCETEK distributors provide after sales and service maintenance which include Operation, Training, Maintenance and Application. According to vanguard’s professional management technology, we provide service quality and customer satisfaction for after sales service support.
