ID Honing

Utilize an abrasive stone,which turns while being moved in and out of the work piece.

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.

100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
