Product Description

Processing advantage

This tool is a professional tool for machining cylinder bore, especially for finishing of Cold-drawn Tube bore. It has fast efficiency and high precision. It is more than 10 times that of ordinary honing. It can process one meter in 1-3 minutes. The tool adopts reciprocating processing technology. It cuts the hole allowance when feeding forward, burnish back, and the surface roughness can reach Ra0.05-0. 2. Surface hardness can be doubled to increase the service life of cylinder.
Skills

Skiving and burnishing processes are carried out separately to help maintain low power requirements and feed force.

Feed and speed can be optimized for skiving and burnishing processes respectively.

It is the best scheme to improve tool life and machining safety.

Procssig method

Single rotary processing mode: Workpiece fixed, tool rotary feed processing

Processing method: Cutter feed into the inner hole first to finish boring and cutting the cylinder bore, to the end  and return to the inner hole for burnishing processing.

Product data

Spare parts

Application:

1.Extrusion of pipes, such as seamless steel pipes or cold-drawn pipes;

2.Diameter range: 38-300 mm

3.Typical parts: hydraulic cylinder and cylinder;

4.Machine tools with forward and backward feeding functions can provide optimum performance and maximum machine tool utilization.

Main features

1. Increasing the surface roughness, the roughness can basically reach Ra < 0.08um.

2. Amend roundness, ellipticity can be less than 0.01mm.

3. Increasing the surface hardness, eliminating the stress and deformation, and increasing the hardness by HV > 4

4. Because the surface residual compressive stress is retained on the surface, it helps to seal the surface micro-cracks and hinders the expansion of erosion, thus improving the surface corrosion resistance and delaying the generation and expansion of fatigue cracks, thereby improving the fatigue strength of cylinder barrel.

5. The rolling surface can form a cold working hardening layer, which improves the wear resistance of cylinder inner wall. Improve the quality of matching, reduce wear and tear, prolong the service life of parts, but reduce the processing cost of parts.

6. Improving processing efficiency: the processing speed is nearly ten times that of honing.

7.Optimizing working environment: low noise, no pollution, saving labor costs

8.Optimizing processing procedures: Scraping and rolling can be used as the last process to arrange processing after other processes (such as drilling oil hole, welding, turning thread, etc.) have been completed. The burns caused by traditional grinding process are effectively avoided.
