Business areas and features
We cut ultra-precision parts used in medical equipment, semiconductor equipment, precision equipment, and office automation equipment with micron-level accuracy. We can machine shafts, copper, thin-walled long holes, composite shapes, small-diameter composite shapes, development and experimental products, and so on. The equipment we have in our company includes NC composite lathes, NC lathes, NC automatic machines, machining centers, centerless machines, burnishing machines, and so on.
Overview of main products and technologies
For shaft machining, we achieve surface roughness of Rz 0.4 or less, and roundness of 0.003 or less. We manufacture high-precision shafts with an outside diameter tolerance of 0.003 or less, with a diameter of up to 40 mm and up to about 2,500 mm long, whether hollow or solid.

For copper machining, we have a dedicated copper processing line. We handle machining by lathe, machining center, and composite processing, for diameters up to about 300 mm.

For thin-wall and slot machining, we achieve roughness of 0.4a, wall thickness of 0.1 mm, and depth of 300 mm. Mass production can be realized with all cutting processes. We propose weld-free products.

For composite machining, we offer high-precision composite machining for all six faces, regardless of the type of material.

For small-diameter composite machining, we machine small composite products from 4 to 32 mm in diameter.
Message from the CEO (efforts to develop sales channels in the future, how we will use J-GoodTech, etc.)
In our metal cutting business, which we have been engaged in since our foundation, we turn troublesome and un-processable products into processable products, by making use of the technological capabilities and ingenuity we have been cultivating for many years. At the same time, we will also build a corporate structure that can flexibly respond to corporate social responsibilities such as environmental responsiveness and compliance. We will do our best to become your cutting manufacturer of choice.
