honing stinless steel cylinder

1． The honing steel pipe is also called the honing cylinder, which is widely used in: engineering machinery, hydraulic cylinder, metallurgical machinery, plastic machinery, hydraulic gate crane machinery, coal mine hydraulic prop, road construction machinery, textile machinery and other industries.

2.  The basic process of the honing pipe:

(1) the materials are continuous-rolling pipes which are all made of TPCO, Tianjin, big seamless continuous rolling machine

(2) tube inspection, pickling, phosphating, saponification of tubes

(3) cold drawn processing to form cold drawn tubes

(4) apply the honing machine to hone the cold drawn tubes.

Honing is also a way of polishing. Honing is only used for the polishing of holes in the steel tube. Honing is a high precision grinding process. Honing has a special honing head, which is equipped with all kinds of thick or thin oil stones to polish the inner surface. It is installed on the floating clamping device, which can adjust itself in a very small amount, so it can adapt to the shape difference of the holes. Its working state is the slow circular movement of the oil stone and the relatively fast axial movement, making the inner hole size meets the requirements of the technology.

The process and characteristics of honing steel tubes 1. improve surface roughness thus can reach Ra≤0.4um.  2. Correction of roundness, the ellipticity can be ≤0.01mm. 3. improve the surface hardness, eliminate the stress deformation, improve the hardness HV≥4° 4. The residual stress layer is existed after processing, improve the anti-fatigue strength by 30%. 5. improve the product`s quality, reduce wears and tears, and extend the cylinder`s service life.
