About Ceramics

Ceramics are vital materials in ultra-precision processing because of their extremely small thermal replacement. Sodick owns the production technology for ceramic high durable machine structural parts and hydrostatic bearings, which help to achieve the high-precision positioning. Using our company’s ceramics in the main parts of the machines, which offer characteristics such as durability, light weight, heat resistance, and abrasion resistance as well as electric resistance critical for electric processing machine materials, forms a lightweight, durable machinery structure.


Sodick provides from materials to products according to customers needs, focusing on the following three areas: aluminum oxide (Al2O3), zirconium dioxide (ZrO2), and silicon nitride (Si3N4).
Sodick develops products by making the best use of ceramic characteristics.

Background of Development

Iron expands by 10 micrometers per meter with the increase of 1ºC each. Thus the center position of the wire shifts when the work is processed by wire electrical discharge machines. On the other hand, it is said that ceramics show less than one-third of that thermal displacement. Based on our own research, Sodick found it most appropriate to adopt ceramics in the arm parts. At that time, however, there was no company which offered ceramics, so we began production of ceramics for electrical discharge machines. At the beginning, we manufactured only parts necessary for our Sodick products, but due to high demand, the ceramics manufacturing department was spun off Sodick FT EMG Co., Ltd., an independent operation. Now, in addition to Sodick products, we supply companies that produce measuring devices and semiconductor manufacturing system.
