Ürün Açıklaması

 LianGe Honing Tube
 

1. Description: Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn pipe is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need.
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder. 
2. Commodity: Cold Rolled Precision Honed Steel Pipe
3. Size range:  Inside diameter: 25mm -500mm; Wall thickness: 2-50mm
4. Available steel grade: 

SAE/AISI:	SAE1020, SAE1026, SAE1045, SAE4130, SAE4140
DIN:	ST52, ST52.3, ST52.4
EN:	E355, C45E, 25CrMo4, 42CrMo4, CK45, S45C, E410, E470
GB:	20#, 45#, 16Mn, Q345B, Q345C, Q345D, Q345E, 25Mn, 27SiMn,

5. Manufacture method: Cold rolled, hydraulic cold drawn, hot rolled+deep hole boring
6. Delivery condition: 

BK	BKW	BKS	GBK	NBK	Q+T
+C	+LC	+SR	+A	+N
Cold rolled	Cold drawn	Stress relieved	Annealed	Normalized	Quenched+Tempered

7. Bore treatment: Honing, skiving&roller burnishing
8. Bore roughness control: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes. 
9. End finish: Plain ends with square cuts, free of burrs for honed tubes. Little bevelled ends for skived&roller burnished tubes. 
10. Standard export packing: In bundles tied with steel strips. Internal & external oil coating. Plastic caps on both ends. External packing by PVC bags and knit bags. 
11. Customized packing and marking can be provided upon request. 
12. H8 tolerance: 

ID range	Tolerance	ID range	Tolerance
18< d ≤30	+0/+0.033	180< d ≤250	+0/+0.072
30< d ≤50	+0/+0.039	250< d ≤300	+0/+0.081
50< d ≤80	+0/+0.046	300< d ≤315	+0/+0.081
80< d ≤120	+0/+0.054	315< d ≤400	+0/+0.089
120< d ≤180	+0/+0.063	400< d ≤500	+0/+0.097

13. Difference between honed tube and skived & roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness.
