ID Honing
The honing process makes ：
1.Smooth surface finishes inside bores
2.Hold precise tolerances on bore diameters
ID H7 H8 H9
ID roughness 0.2-0.8μm
ID max 630mm
Roller Burnish+ Skiving
Two thin chips are cut at high feed rate while the tool passes through the workpiece.producing super finish surface,with a bore precise tolerance .
ID H7 H8 H9
ID roughness 0.2-0.8μm
ID max 630mm

QUALITY CONTROL
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking.
