Mass Production of Taper Pins & Straight Pins｜Precision Manufacturing with Japanese-Quality CNC Lathes

High-precision mass production of taper pins and straight pins. Using CNC lathes and cam-type lathes, we deliver Japanese-quality precision machining capable of handling materials that are difficult to machine and control burrs.Overview
Taper pins and straight pins are critical components used for high-precision positioning and joining in inspection machines and precision equipment. For taper pins, which require precise angle accuracy, the control of angles during continuous processing and the prevention of burrs are essential for quality. Our company combines stable processing technology using CNC lathes and cam-type automatic lathes with Japanese-quality process management, comprehensively manage wear, burrs, and machined surface quality. We ensure consistent mass production quality even for materials that are hard to machine like SUS304 and brass.
