High-precision outer diameter super finishing spool after cutting, heat treatment, and special deburring, with an outer diameter tolerance range of 2μ.
The material being machined is chrome-molybdenum steel, which is subjected to carburizing and quenching after cutting, and then the outer diameter is finished with super finishing grinding.

Introduction of case studies on gas nitriding, blackening treatment, and centerless grinding of general-purpose parts "spools."
This is a case study on gas nitriding, blackening treatment, and centerless grinding of a general-purpose part called "spool." The material is supplied by the customer, and heat treatment and centerless grinding are performed. The grinding process after heat treatment is handled by a partner manufacturer of ITEC. 【Processing Details】 Product Name: Spool (General-purpose part) Material: S48C Lot: 1000 pieces/lot *For more details, please refer to the PDF available for download.

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.

Managing outer diameter dimensions within ±1 micron! We pursue sub-micron precision to meet various needs.
We would like to introduce a machining example of a "spool valve" used for switching directions and paths. Our company precisely manages workpieces with a total length of 200mm to an outer diameter dimension of less than 3μ (microns = 0.001mm), roundness of less than 2μ, and cylindricity of less than 3μ. Furthermore, we perform grinding after hard chrome plating to meet the required precision of less than 2μ for outer diameter dimensions. Please feel free to contact us when you need our services. 【Case Overview】 ■ Achievements: 1500/month ■ Possible quantity: 5000/month ■ Material: SCM415N ■ Total length: 100mm ■ Outer diameter: 14 (+0.009/+0.007) *For more details, please refer to the PDF document or feel free to contact us.
