The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

This is an introduction to "outer diameter film polishing," which is used for ultra-finish machining of various shaft-type workpieces. - Wouldn't you like to achieve ultra-finish machining more easily, safely, and with less variation? Please take a look at what film polishing is, along with related products and catalogs!
