Roughing tools typically use wavy cutting edges or large rows of cutting flutes with large contact surfaces. Finishing tools usually use sharp cutting edges and high tool strength. The cutting edges are sharp and high in strength, reducing the problem of side milling taper and improving the finish surface quality.
The difference between roughing and finishing is that roughing removes a wide variety of materials, with low cutting speeds, large feeds and tools, less material removal, and high cutting speeds to ensure final dimensional accuracy and surface quality. Roughing is mainly for the purpose of quickly cutting the remaining margins.
During rough machining, for the processing of soft materials such as copper and aluminum, the amount of deep chip removal is large. When cutting, a large amount of chips can be removed, and a large feed rate and as large a cutting depth as possible can be used to cut as much as possible in a short time. Possibly a lot of chips.
Superfinishing is usually carried out after the finishing process with a machining allowance of only a few microns. It is suitable for processing crankshafts, rollers, bearing rings and outer rings, inner rings, flat surfaces, groove surfaces and spherical surfaces of various precisio
