Processing principle of CNC computer gong

CNC processing is specialized in mechanical processing. With many years of practical experience, I would like to talk about the specific processing principles of mechanical processing

(1) In order to ensure the machining accuracy, rough and finish machining should be carried out separately. Because of the large amount of cutting during rough machining, the cutting force and clamping force on the workpiece are large, the heat value is large, and there is a significant work hardening phenomenon on the machined surface. There is a large internal stress in the workpiece. If rough machining and rough machining are carried out continuously, the precision of the parts after finish machining will be quickly lost due to the redistribution of stress. For some parts with high machining accuracy. After roughing and before finishing, low temperature annealing or aging treatment should be arranged to eliminate the internal stress.

(2) Reasonable selection of equipment. Rough machining is mainly to cut off most of the machining allowance, and it does not require high machining accuracy, so rough machining should be carried out on the machine tool with high power and low accuracy, while finish machining requires high accuracy. High speed computer gong rough and finish machining in different machine tools, not only can give full play to the equipment capacity, but also can extend the service life of precision machine tools.

(3) Heat treatment process is often arranged in CNC machining process. The location of heat treatment process is as follows: in order to improve the cutting performance of metal, such as annealing, normalizing, quenching and tempering, it is generally arranged before machining. Mechanical parts processing to eliminate internal stress, such as aging treatment, quenching and tempering treatment, generally arranged after rough machining, before finishing. In order to improve the mechanical properties of parts, such as carburizing, quenching, tempering, etc., it is generally arranged after machining. If there is large deformation after heat treatment, the final processing procedure must be arranged.

1. Understand the shape, structure and corresponding graphic position of parts.
2. Look at the benchmark of the parts. Axis line, hole center line, surface, etc.
3. Look at important dimensions, accuracy, roughness, form and position tolerance, etc.
4. Look at the technical requirements, materials, etc.
5. Look at the three views, left view, right view, top view, section view, detail drawing, etc. to understand the outline structure and facilitate cutting.
6. Focus on the tolerance accuracy requirements of machining, including roughness, etc.
7. Heat treatment and hardness requirements in technical requirements.

Pay attention to tolerance, fit tolerance, finish and concentricity
