We are processing grinding after hard chrome plating with an external diameter dimension accuracy requirement of 2μ or less!
We would like to introduce a machining case of a "spool valve" used for switching directions and paths. Our company precisely manages a workpiece with a total length of 200mm, with outer diameter dimensions of 3μ (microns = 0.001mm) or less, roundness of 2μ or less, and cylindricity of 3μ or less. By improving the jig (Kere), we can perform simultaneous grinding processing even at distant positions. 【Case Overview】 ■ Achievements: 2000/month ■ Possible quantity: 3000/month ■ Material: SCM415 ■ Total length: 44 ■ Outer diameter: 9.525 (-0.005/-0.008) *For more details, please refer to the PDF document or feel free to contact us.
