What is the difference between a CNC lathe and a fine turning tool?
(1) front Angle: the Angle of the cart is small, the fine car is larger. (2) rear Angle: the rougher Angle is smaller (6-8 degrees) and the fine car is larger (10-12 degrees). (3) tilt Angle: when a rough car is usually 5 degrees, it may be 10 degree or larger when it is large. In fine cars, the average is -4 degrees. (4) main Angle: according to machine tool, workpiece and tool system stiffness choice. (5) partial Angle: according to surface roughness choice, high time Angle is smaller. (6) radius of the tip arc: general carbide turning point r = 0.5-2mm, small value when rough car. Roughing tool and finishing tool is relative, the same machined part, finishing tool for processing the final processing requirements (tend to be sharp, cutting groove narrower), roughing tool can bear larger cutting force, roll cutting groove wider and has broken cutting ability, material requirements red hardness, better able to withstand high temperatures.
The thick blade is generally wide, the rear Angle is small and the blade is big. A fine car knife is the opposite.
The main difference is the grooves of the tool and the tip of the blade, and the other is a small difference in the material.
