Lathe processing factory CNC lathe processing is a high-precision and efficient automatic machine tool, which uses digital information to control parts and tool displacement processing methods. It is an effective way to solve the problems of aerospace product parts variety, small batches, complex shapes, high precision, etc., and realize automatic processing. Generally, there is a heat treatment process in a workpiece processed by a CNC lathe. Then, what step is there in the heat treatment of a workpiece processed by a CNC lathe?

1. Prepare for heat treatment. The purpose of pre-heat treatment is to improve cutting performance, eliminate residual stress in the era of CNC lathe blank manufacturing, and improve the structure. The process position is mostly before mechanical processing, and is often used for annealing, normalizing, etc.

2. Heat treatment to eliminate residual stress. Since the internal stress of the billet in the manufacturing process will cause the deformation of the workpiece and affect the processing quality, it is necessary to arrange a residual heat treatment. The residual stress heat treatment should be arranged after rough machining and before finishing.

For parts with low precision requirements, artificial aging and annealing are usually carried out to eliminate residual stress before the blank enters the machine shop. For complex castings with high precision requirements, two aging treatments are usually arranged during the machining process: casting-rough aging-aging-semi-finishing-aging-finishing. For high-precision parts, such as precision steel wires, precision spindles, etc., multiple heat treatments should be arranged to eliminate residual stress, or even cold treatment to stabilize the size.

Then heat treatment. The purpose of the final heat treatment is to improve the strength, surface hardness and wear resistance of the parts, and is usually arranged before the finishing process (grinding). Commonly used are quenching, carburizing, nitriding and carburizing.
