Hardwareindustry Micro shafts of hardware and instrument series

6.Processes

We often use ERP system to producing quality control, the processes for the shafts are usally the following:

Raw material(Drawn) → Cutting→Rolling →lather→grinding→polish→final inspection→pick up→package→delivery

We can offer PPAP documents,such as control plan, PFEMA, Process flow .etc

7. Raw material


Materials:

Carbon steel:SK45 CK45,EN8,60#,70#,80#

Stainless steel :SUS303,SU304, SUS316, SUS416,SUS420J2

Others: AISI4140, 42CrMo,ETG88 1144 12L14,430f,431100Cr6, SUJ2, Gcr15

Raw materials are ROHS tested from the third party every year, such SGS, CTI.

8. Machines:




Ball Grinding machines, to make the end of shafts


Auto lathers, to do lather process, like groove


Coreless grinding machines- this are the most important machines making the shafts

9. Testing devices, we have our own testing certer. we have all shafts devices
