Marusawa Kikou Co., Ltd.

We take on the challenge of machining parts with submicron-order accuracy.

Our company can experimentally manufacture or mass-produce products with complicated shapes machined with high accuracy. We can also comprehensively stabilize quality in terms of dimensional accuracy and appearance. We have built up a track record and know-how by experimentally manufacturing or mass-producing a great variety of parts. Applications of our products include communications equipment, medical equipment, semiconductor manufacturing equipment, and hydraulic and pneumatic equipment. We make use of comprehensive strengths in CNC lathing, machining, wire cut EDM, lapping, and assembly. We can finish inner and outer diameters with high accuracy just by machining. We also take on the challenge of addressing partial peeling of plating from micro parts, thin-product machining, and mirror machining.

Mechanically engineered product part machining and assembly 

[Strength of products/technologies]
Our company has built up a track record and experience through precision machining and assembly related to optical communications equipment. We are applying this experience in machining precision parts with CNC automatic lathes, machining centers, and plane lapping machines. We also assemble mechanically engineered products, including bonding, joining, and press-fitting. We have achieved nano-order (100 nm) accuracy. We can obtain parts at low cost by making use of our strengths in material procurement and in-house production when assembling mechanically engineered products. We are working to maximize yields in press-fitting with micron-order inner and outer dimension management based on our in-house processing technologies.

[Representative's message]
Our company has been manufacturing a great variety of precision parts since our establishment in 1949. We mainly handle machining for communications equipment, OA equipment, medical equipment, and aerospace-related equipment. We take on the challenge of manufacturing parts with submicron-order accuracy. We integrate mind, technology, and information. “Quick Response & Good Communication” is our motto, and our management objective is to be a company capable of continuous innovation to quickly satisfy customer requests.
