Why does a lathe tool have a rear Angle? How is its size chosen?
The lathe also calls machine tool, the worker that USES lathe is called "lathe work", in machine processing industry the lathe is regarded as the work "mother machine" of all equipment. The lathe is mainly used for machining shaft, disc, sleeve and other parts with rotating surface, which is mainly the cylinder, the main motion is the lathe tool, the workpiece is not moving. It is the most widely used type of machine tool in machine manufacturing and repair shop. The machines, such as milling machines and drill beds, are drawn out of a lathe. People in Hong Kong and other places in China also called lathes.
That is to reduce the friction between the workpiece and the rear blade. In rough machining, the material of the workpiece is smaller when the material is hard, and the finished processing or the material is softer
The rear Angle of the car knife is to prevent the item from causing friction. The size of the rear Angle determines the strength of the tool, the impact resistance, the heat dissipation. Process quench workpiece, hard work piece, can choose negative front Angle, small back Angle cutter. The workpiece is soft, such as copper. To finish the process, you need to increase the Angle before and after, and add the coolant when necessary. In order to reduce friction and elastic deformation, the quality of processing is affected.
A lathe is a machine tool that is used for turning the rotating parts of a lathe with a lathe. It can also be processed with drills, reamer, reamer, tap, die and roller.
