Tubes Maching
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
