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.

Packing & Delivery                                                                                 

 
Packing Details : In bundles or in wooden boxes packaging of honed tube
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

ASTM A519 Hydraulic Cylinder Alloy Steel Mechanical Honed Tubing

In bundles with end caps.well protect tubes from rust.

Carton Packing suit for the cutting length
