Precise Microscopic Laser Processing　(Laser, Wire EDM, Etching)

A Table of Processing Blank

Processing method as below is upon your quantity and precision.
Not only the following processing, but also die blanking, laser processor and turret punch press are achieved.
A free sample is made when it comes to confirmation of section or finish.

Feature of Microscopic Laser

• High precision and minutiae parts.
• Minimum slit: (w) 0.1 mm.
• Nonferrous metal, copper, alloy and various plating material except pure copper are achieved to process.
• No hole needed before threading.
• Quick processing and delivery can be in 1 day (It depends on parts and shapes).

Material：SUS304, Thickness：0.2

Material: Phosphor bronze (C5210）、Thickness：0.1

Feature of Wire EDM　φ0.05

• The electrode of the wire EDM is φ0.05, that enables to be more minute shapes.
• Minimum inside radius is 0.04.
• Prototype is made same precision as that of mass production.
• The most suitable for high-precision minutiae parts.
