What are the processing methods of CNC lathes?

What is the processing method of CNC lathe? There are two main forms of CNC lathe processing in production and processing, namely solid heat treatment and melt heat treatment. There are some differences between precision hardware machined parts made with these two methods. Also, the workpieces they make will vary depending on the steel used. The CNC lathe consists of a bed, a spindle box, a tool post feed system, a cooling and lubrication system and a CNC system. Different from ordinary lathes, the feed system of CNC lathes is qualitatively different from ordinary lathes. It does not have the traditional tool box, sliding box and gearbox, but directly drives the sliding plate and the tool to realize the feeding movement with the servo motor or stepper motor through the ball screw. The numerical control system is composed of numerical control unit, input and output module and operation panel.

 1 Solid solution strengthening: When the solute atoms enter the gaps or nodes of the solvent lattice, the lattice is distorted, and the hardness and strength of the solid solution increase. This phenomenon is called solid solution strengthening phenomenon.

 2. Compounds: Alloy components combine to form new crystalline solid structures with metallic properties

Mechanical Mixture: An alloy composition consisting of two crystal structures. Although it is two crystals, it is a component with independent mechanical properties.

1. Ferrite: An interstitial solid solution of carbon in α-Fe (iron with a body-centered cubic structure). Austenite: Interstitial solid solution of carbon in g-fe (iron with a face-centered cubic structure). Cementite: Made of carbon and iron.

 4 The stable compound (Fe3C) formed. Pearlite: A mechanical mixture of ferrite and cementite (F+Fe3C with 0.8% carbon).

 5 ledeburite: a mechanical mixture composed of cementite and austenite (containing 4.3% carbon). Metal heat treatment is one of the important processes in machinery manufacturing. Compared with other machining processes, heat treatment usually does not change the shape and overall chemical composition of the workpiece, but imparts or improves the performance of the workpiece by changing the microstructure in the workpiece or the chemical composition of the workpiece surface.
