Curve hole machining is a new technology of the Company that can be processed a hole with a curvature(R).

Curved hole machining three types, the first technology can be processed at a constant R, the second the technology can be processed by combining two curvatures, the third the technology can be processed leading from the straight to R shape.

It should be noted, can be processed materials is stainless steel, Hastelloy, Inconel.

System in the electrical discharge processing business

  1. We can consistently processing to delivery from the purchase of material.
  2. Available upon contract processing also happily in semi-finished products and prototypes.
  3. Equipment sales in conjunction to the processing content and corresponding to meet the customer's needs is possible.

Strength in the electrical discharge processing business

  1. Processing track record over more than half a century.
  2. Japan's largest in the full-time of electrical discharge processing (metal working).
  3. It can be a wide range of support from micro processing to large processing.
  4. We realized the processing reform and cost reduction by developed in-house special-purpose machine.
