The power of skiving roller burnishing machine is 5-8 times higher than that of ordinary deep hole and honing. It is a processing equipment for manufacturing hydraulic cylinders. He integrates rough boring and fine boring, uses push boring to finish rough and fine boring at one time, and ends the rolling process at the time of tool withdrawal after boring. Rolling processing makes the workpiece roughness reach Ra0.4. Deep hole processing rolling technology is a non cutting processing.
After plastic deformation, the inner surface reaches the required surface roughness of the workpiece. Advantages of rolling: the surface roughness of traveling can reach RA ≤ 0.4 μ M or so. Modify roundness, Ovality ≤ 0.03mm, coaxiality ≤ 0.06mm, travel surface hardness, eliminate stress deformation, and travel hardness HV ≥ 4 °.
There is a residual stress layer after processing. The travel fatigue strength is 30%. The travel cooperation quality reduces wear and extends the service life of parts, but the processing cost of parts decreases. Machining accuracy: workpiece boring surface roughness ≤ ra3.2 μ m. Workpiece rolling surface roughness ≤ Ra0.4 μ m. Workpiece processing cylindricity ≤ 0.027/500mm. Workpiece processing roundness ≤ 0.02/100mm
