Following these principles when CNC machining parts can greatly reduce the processing cost!

CNC machining is also known as machining. Machining is to use CNC machining centers to carve and mill raw materials into * * * finished parts or product shapes. Zhongdou Precision has been focusing on parts processing for many years and has accumulated rich experience in machining CNC machined parts. When machining parts with CNC, the following principles are generally followed to reduce costs.

1. First rough machining and then finish machining to ensure accuracy and finish;

2. Machine the surface first and then the hole position;

3. The hole position shall be milled first, and the drill shall not be milled. If * * * can be made at one time on the CNC machining center, the time for repeated clamping and the error caused by positioning can be reduced;

4. For cavity products, first process the inner cavity and then the shape;

5. The sequence of processes is different, and the diameter of processing tools varies from large to small;

6. Sorting the same fixture and fixture together can reduce the cost of making the fixture and the time of repeated clamping;

7. Thin products should be rough machined first, and then placed for a period of time before finishing to reduce deformation;

8. The heat treated products shall be opened first, with allowance left for heat treatment, and then returned for finishing;

9. For products requiring surface treatment (such as oxidation, electroplating, powder spraying, etc.), allowance shall be reserved according to the corresponding surface treatment during processing to ensure that the size requirements required by customers can be met after surface treatment.

10 .  The parameter is set from primary to secondary.

CNC processing involves many materials and processes, so it will encounter various problems during processing. Only by accumulating certain experience can we calmly deal with them. The engineering team of Zhongdou Precision has 12 years of experience in CNC machining parts, is good at machining complex and multifaceted products, and dares to challenge others to do things they don't want to do!
