Machine Tool Applications:
◆ The CNC deep-hole boring, reaming, and rolling machine offers efficiency 5-8 times higher than that of conventional deep-hole boring and honing machines.
◆ It is a specialized processing equipment for manufacturing hydraulic cylinders.
◆ It integrates rough boring and finish boring into one process, utilizing push boring to complete both rough and finish boring in a single pass. After boring, it takes advantage of the tool retraction moment to simultaneously complete the rolling process.
◆ Rolling processing enables the workpiece to achieve a surface roughness of Ra0.4.
◆ Deep-hole rolling technology is a non-cutting process that achieves the required surface roughness of the workpiece through plastic deformation of the inner bore surface.
Advantages of Rolling:
◆ Improves surface roughness, generally achieving Ra ≤ 0.4μm.
◆ Corrects roundness, with ellipticity reaching ≤ 0.03mm and coaxiality ≤ 0.06mm.
◆ Enhances surface hardness, eliminating deformation under load and increasing hardness by HV ≥ 4°.
◆ Leaves a residual stress layer after processing, improving fatigue strength by 30%.
◆ Improves fit quality, reduces wear, and extends the service life of parts, while reducing processing costs.
Machining Accuracy:
◆ Surface roughness of the bored workpiece ≤ Ra3.2μm.
◆ Surface roughness of the rolled workpiece ≤ Ra0.4μm.
◆ Cylindricity of the processed workpiece ≤ 0.027/500mm.
◆ Roundness of the processed workpiece ≤ 0.02/100mm.
