Product description

Parameters

Machine tool usage:

◆CNC deep hole boring and scraping machine, the efficiency is 5-8 times higher than ordinary deep hole and honing.

◆It is a processing equipment specialized in manufacturing hydraulic cylinders.

◆It integrates rough boring and fine boring. It uses push boring to complete rough and fine boring at one time. After boring, the process of rolling is completed at the same time when the tool is retracted.

◆Rolling processing makes the roughness of the workpiece reach Ra0.4.

◆Deep hole processing rolling technology is a kind of non-cutting processing, through plastic deformation, the inner hollow surface can reach the surface roughness required by the workpiece.
Increased advantages of rolling:

◆Improve the surface roughness, the roughness can basically reach Ra≤0.4μm

◆Correct roundness, ellipticity can reach ≤0.03mm, coaxiality ≤0.06mm

◆Improve the surface hardness, eliminate the stress deformation, and increase the hardness by HV≥4°

◆There is a residual stress layer after processing. Improve fatigue strength by 30%

◆ Improve the quality of the fit, reduce wear and extend the service life of the parts, but the processing cost of the parts is reduced

Precision:

◆The surface roughness of workpiece boring≤Ra3.2μm

◆Roughness of workpiece rolling surface≤Ra0.4μm

◆Cylindricity of workpiece processing≤0.027/500mm

◆Workpiece processing roundness≤0.02/100mm
