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.

Generation of the burrs of the processing surface port is restrained substantially.
It adopts the unique circuitry that the processing current value goes up automatically for every step from 0 to the goal setting value in the CPU circuit which is built-in to the power source. As a result, the burrs generated at a processed surface is suppressed substantially, and a good surface is obtained.
High-speed processing is achieved from a small diameter to the large diameter of the hole.
Since introduction of the high power source which optimized processing of various materials (metal) can perform high-speed processing from the small-hole to the large and deep hole, the substantial improvement in production efficiency is possible.
Small head (2Z400)
It is the small head which is easy to incorporate in an automation line.
The integrated design and the hole of the special order is also available.
The integrated design from the feed of the work piece to the ejection of it and larger diameter than φ3.0 can also available according to your needs.
AUTO processing function
It performs automatically from the start of the processing to the end of the processing by only one signal.
"3-step" processing function
In order to lessen attaching of the fusion substance at the processing port and to improve processing stability of the processing outlet port, three kinds of processing conditions according to a processing depth are performed by automatic switching.
"F-step" processing function
Since the electrode will move quickly the work piece and processing will be started if the distance between the tip of the electrode and work piece is inputted into "F-step", large reduction of the processing time is possible.
"Soft-limit" function
When it becomes shorter than the numerical value which the electrode set up during processing, the Z-axis goes up automatically after the processing end.
Electrode consumption check function
Processing which makes the hole is confirmed by the consumption of the electrode whether it is normal.
Counting function
It outputs a signal by the set-up number of times of processing.
