栃電社 Product Lineup

Tochiden Co., Ltd. achieves "±3μm level precision" primarily through cylindrical grinding, centerless grinding, and internal grinding. The assembly areas of important drive components such as crankshafts and connecting rods require lapping, but we have developed high-precision processing technology that allows assembly without lapping. By applying highly precise machining to the inner spherical part of the connecting rod, we enable cost reduction in manufacturing, improve productivity, enhance durability, and achieve cost savings. 【Features】 ■ Capability to handle eccentric shafts and irregular shapes ■ Support for spherical grinding ■ Lapping-free and grinding-free technology *For more details, please download the PDF or feel free to contact us.
