"Honing processing" is an excellent machining method that can precisely polish the inner surfaces of cylindrical machine parts, such as engine and hydraulic equipment cylinders. By applying micro-vibrations in addition to rotational cutting with an electroplated grinding wheel, vibration grinding allows for high-precision finishing of cylindricity, straightness, and surface roughness in a single pass. Furthermore, the machining accuracy is as follows: cylindricity within 1.5μ, roundness within 1μ, and surface roughness Ra within 0.05. (This includes material, processing length, previous processes, and various conditions.) 【Features】 ■ High-precision finishing of cylindricity, straightness, and surface roughness in a single pass ■ High-precision machining can be achieved in a short time with just one pass of the tool through the workpiece ■ Machining accuracy: cylindricity within 1.5μ, roundness within 1μ, surface roughness Ra within 0.05 (including material, processing length, previous processes, and various conditions) *For more details, please refer to the PDF document or feel free to contact us.
