We mainly engaged in surface processing such as metal processing, HVOF thermal spraying, alumite treatment, SEP processing etc. of precision machining and polishing processing, etc. In precision machining / polishing processing, we flexibly respond to customer's needs from large lot to various kinds of small lot. In HVOF thermal spraying, we adopt advanced technologies such as processing of airplane parts and thermal spraying on resins. As for alumite treatment, lubricating alumite, water repellent alumite, etc. in addition to hard alumite are performed. Having been pursuing "melting" technology for SEP treatment, we remove fine burr of metal parts such as iron, stainless steel and copper. These technologies have allowed us to create a system for integrated production from machining to finishing.

SEP is a technique to eliminate burrs from products by immersing the product in a specific liquid. This allows burrs to be removed from thin workpieces and parts with complex shapes.
