Precision Polishing Technology

Our special polishing technique is an original method which was developed by working unflinchingly on the polishing of shapes and materials which many people abandon, saying that the polishing is difficult or impossible with conventional methods, such as grinding, electrolysis, blast, buff, and barrel. We can perform mirror finish of a rough surface along the shape. Please see processed examples below.

We achieved mirror finish of discontinuous surfaces such as peaks, sides, and valleys of the inner surface of a flexible tube used for semiconductor manufacturing equipment which represent ultra clean technology. As one of the key points of contamination control, there is a surface roughness of the inner surface of a fluid path pipe for pure water, high-purity gas, and chemical. Our special polishing could get the finished surface either equaling or surpassing electrolytic polishing or chemical polishing. Moreover, we can uniformly polish the whole area of the corrugated surface of vaccum seramic pinchuck

In the field of medicine or analytical equipment, the pipes which are narrow and bent, manufactured by spinning or to taper have been increasing, but we can polish them. We can polish pipes, if their inner diameter is 0.003inch and their length is 39.4inch or if their inner diameter is 0.007inch and their length is 78.8inch.

Automatic Assembly Machine

We think that the basics of producing automated equipment or laborsaving equipment are to meet three conditions: space-saving, high functionality, low-cost

The history of the business started when the department of manufacturing contract
(subcontract manufacturing) took the first step into the in-house manufacturing of
production equipment in order to win the competition with our clients (the owner)
or competing rivals in the industry in the field of QCD.

In the initial step of organizing the automation of production process, we start by thoroughly observing and analyzing the actions of workers (movements of arms, legs, fingers, line of sight) in the manufacturing floor and the movements of objects (parts and work tools).

As one of the characteristics of development design of our own facilities, there is an idea that function is nothing special and a compact design to minimize the installation space is necessary. This is a big challenge to create higher added value through a limited factory space.

We have confidence about the know-how we had accumulated through our great efforts to meet “space-saving, high functionality, and low cost” at manufacturing premises for
over 30 years.
