Description: honing is a machining process, using the honing head to hone the cold drawn tube inner hole with high-speed reciprocating processing, which to make the tube inner hole meeting the required precision tolerance and surface roughness. According to customers requirements, our hone tube tolerance can be H7, H8, H9, H10, roughness can be Ra ≤0.4μm, ovality within 0.03mm - 0.05mm.



Advantages of PRIOR MACHINERY hone tube:

1. With good surface, roughness can be 0.02μm - 0.04μm.

2. Finished products the ovality is within 0.03mm - 0.05mm, after adjusting, ovality can be ≤0.02mm.

3. After honing, tube surface harness is improved (HV≥4º), eliminate stress deformation.

4. There is residual stress layer after processing, which improving the fatigue strength by 30%.

5. Abundant production experiences - specialized at producing cold-drawn tube, hone tube since 2003, over 15 years producing experiences.

6. Quality raw material - to ensure producing high quality tube and saving producing cost, we choose the material from Baosteel, Huaisteel and Tiansteel.

7. Advanced producing equipment - we have 350T high precision cold drawn hydraulic units, dozens of large honing machines, straightening machine, cutting machine, complete measuring devices and NDT testing equipment to ensure we produce the 100% high quality tube for our products.

8. A full products line -- we have kinds of honing head and mould.
