Sanyuu Seiki Co., Ltd.

Development of sales channels for original rotation electrode discharge machines and PCD tools

We handle cut processing of aluminum, stainless steel, other steels, and various materials, and manufacture various industrial devices. We have built our business in both areas on the strength of know-how for completely meeting individual needs such as high-mix low-volume production. We are a development-oriented proposal-based company rather than a simple contract processing company. We developed an extremely thin PCD tool having a diameter of 0.3 mm or less, using our original rotation electrode discharge machine, and have applied for a patent. We are considering using this technology for PCD drills having diameters of 4-10 mm, and for versatile end mills and ball-end mill in the future.


Other presentation

[Company strength]
Our Processing Department accepts high-mix low-volume production requests with short delivery times. In addition, we are conducting trial manufacturing of PCD drills having diameters of 0.3 mm or less, which are currently not manufactured or sold anywhere in the world, using a discharge machine that we developed. Our PCD drills have a tool life more than 10 times that of carbide drills, and are suitable for processing brittle materials such as ceramics and quartz glass, carbon fiber reinforced plastic (CFRP) and other materials. We are entering new fields including the processing of parts for industrial machines, and offer technology development.

[Business description]
We process parts for industrial machines, automobiles, and automatic electronic component assembly devices. We process, plate and inspect parts using various materials such as aluminum, stainless steel, and other steels, and deliver the processed parts to customers. In addition, we develop new devices such as continuous magnesium casting devices and electric discharge machines for manufacturing polycrystalline diamond (PCD) cutting tools. As a development-oriented company, we are committed to new development.

Metal cut processing

[Representative's message]
The market is witnessing intense competition among companies as the overall amount of work declines, putting downward pressure on costs. The new technology we have developed enables us to manufacture PCD cutting tools which are difficult to produce. We will actively use J-GoodTech to make our technology and company known to customers.

[Company structure for market development/overseas expansion]
We will expand sales channels for specially-developed rotation electrode discharge machines and PCD tools, by using business meetings and exhibitions. To expand sales channels overseas, we will use the network of the Engis Group of Engis Japan Corp., which helped us to manufacture rotation electrode discharge machines.
