Precision machining, there will be a number of products workpiece is not through a one-time production, but rather when the product workpiece is produced, it is only a rough model, if the factory into a real product, which also requires the use of some mechanical equipment for precision machining, precision machining for different product needs, and finally to become a product with value.
In order to ensure the efficiency of precision machining, and the production of qualified products, in the time of precision machining, must follow the four principles.
1, the benchmark first.
In the use of machinery and equipment for product processing, must determine a datum, so that in the subsequent production and processing time so that there will be a positioning reference, clear datum, then we must first produce and process the datum.
2, divide the production and processing stages.
Products in precision machining, for different product requirements to different degrees of production processing, the degree of production processing needs to be divided, if the requirements for precision is not high, so then a simple roughing stage on the line. The progress of the product requirements are becoming more and more stringent, and the semi-finishing and finishing stages will be carried out later.
3、Face first and then hole.
In the time of precision machining, for products such as bracket workpiece, it is necessary to carry out both plane production processing and mechanical hole processing, in order to be able to produce and process the hole accuracy error is smaller, first production and processing plane after production and processing hole is conducive to reducing the error.
4、Light finishing processing.
This production and processing of the basic principles is largely some grinding and polishing processing, it is generally in the product after all the steps to complete the architecture.
