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 .

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.
Tensile Strength Testing
Chemical Composition Testing
Packing & Delivery
Packing Details : In bundles or in wooden boxes packaging of honed tubing
Delivery Details : 30-60days
In hexagonal bundles packaging with woven
In hexagonal shaps,the tubes will be well fixed,so it can avoid the damages when delievey .
In wooden boxes.
Solid packaging ,protecting tubes from damages much better.
In poywooden packaging,It cut the packaging costs also it can protect tubes well
