Division of processing stages at Dongguan CNC Precision Processing Plant

When processing high-quality parts at Dongguan CNC Precision Machining Factory, it is often impossible to use a single process to meet its requirements, but rather to use a knockdown process to gradually achieve the required processing quality.

In order to ensure processing quality and the reasonable use of equipment and manpower, the processing process of parts is usually divided into four stages according to the nature of the process, namely rough machining, semi precision machining, precision machining, and finishing machining.

1. In the rough machining stage, the task is to remove most of the excess metal from the blank, making it close to the finished part in shape and size

2. In the semi precision machining stage, the task is to achieve a certain degree of accuracy on the main surface, leaving a certain amount of precision machining allowance, and preparing for the precision machining of the main surface (such as precision turning and grinding). And can complete some minor surface processing, such as expanding holes, tapping threads, milling keyways, etc.

3. During the precision machining stage, its task is to ensure that each major surface meets the specified dimensional accuracy and surface roughness requirements. The main goal is to comprehensively ensure processing quality

4. During the polishing process, Dongguan CNC Precision Machining Factory requires high precision and surface roughness on the surface of the parts, which requires polishing. The main purpose is to improve dimensional accuracy and reduce surface roughness values. Generally, it is not used to improve position accuracy.
