The sleeve (hard turning process) is a component that guides the outer part of the section where the measuring terminal moves. A cylindrical tolerance of 2 microns for the inner diameter is required to enable precise measurements. The material is stainless steel 440C, hardened to HRC60 or above through vacuum hardening. After heat treatment, the outer diameter is first finished using centerless grinding. With an outer diameter of 7mm and a dimensional tolerance of 12 microns, coaxiality between the inner and outer diameters requires 4 microns, so the inner diameter is processed based on the outer diameter after finishing it. The inner diameter of 5mm is turned with a precision of 10 microns and a cylindricality of 4 microns, and in the final finishing, honing is performed to achieve a precision of 4 microns and a cylindricality of 2 microns. 【Features】 ■ A component that guides the outer part of the section where the measuring terminal moves ■ Made of stainless steel 440C, hardened to HRC60 or above through vacuum hardening ■ Outer diameter of 7mm with a dimensional tolerance of 12 microns ■ Inner diameter of 5mm turned with a precision of 10 microns and a cylindricality of 4 microns ■ Monthly production record of 5,000 units, capable of handling up to 100,000 units *For more details, please refer to the PDF document or feel free to contact us.
