As electrification progresses, the use of electrically insulated Micro Couplings is increasing. Therefore, we will continue to strive to develop couplings that provide the desired functionality by taking advantage of the characteristics of various materials.

In precision machining, we can process a wide variety of materials.
Our major features are our "technical and proposal capabilities," "integrated production," and "quality assurance."

Our strength lies in our superior processing technology for difficult-to-cut materials such as heat-resistant steel, stainless steel, high alloys, pure Ti, and Ti alloys.
Machining difficult-to-cut materials requires the know-how to understand the material properties and why they are difficult to machine, and to select appropriate cutting tools and set machining conditions.
We have been involved in cutting many difficult-to-cut materials, and have thoroughly investigated cutting tools and processing conditions.
The know-how we have accumulated is such that other companies ask us for advice.
Even if you have a material that other companies say cannot be cut, feel free to contact us.

We consider processing methods and conditions from every single aspect.

We have over 50 units of NC lathes and machining centers of various manufacturers and equipment specifications.
High-precision cutting of difficult-to-cut materials may require high rigidity of processing equipment. Therefore, we select appropriate equipment according to the material.
In addition, our technical department thoroughly examines every aspect to optimize quality and cost, including the selection of blade, processing conditions, and the order of processing steps. Therefore, we meet customer requests not only in terms of technology but also in terms of quality and cost.

We can handle high-mix low-volume production.

Our specialty is product sizes ranging from 5 mm to 200 mm in diameter, which can fit in the palm of your hand, but we can also process products of other sizes.
Furthermore, because we use a cell production method, we are able to handle high-mix low-volume production. We are also flexible in accepting product prototypes.
