Ideal for IN-Line Small-Hole Drill EDM for Fluid or Cooling Holes in Automotive and Aerospace Parts.

Components processing of the charge of super-hardwood by small-hole discharge etc. is proposed.
By application to mass production processing, secondary processing is unnecessary and it can be achieved to the higher efficiency of the production.

Since the high-speed small-hole electric-discharge-machining unit of ASTEC can build the optimal automatic processing system unrestricted according to the processing line of various components, the utilization field is substantially expandable. Small-hole electric discharge machining solves the trouble which is generated the burrs in in-line drilling process. Improvement in processing efficiency is excellent and the extensive improvement of the reduction of the processing cost of components or working hours is possible.
