CNC machining, also known as mechanical machining or machining, involves using a CNC machining center to sculpt and mill raw materials into the final shape of parts or products. Zhongdou Precision has been focusing on parts processing for many years and has accumulated rich experience in CNC machining of parts. When machining parts with CNC, the following principles are generally followed to reduce costs.

1. Performing rough machining before fine machining can ensure both accuracy and smoothness;

2. Process the surface first, then the hole locations;

3. Initially, select milling for the hole location. If milling is not feasible, then choose drilling. If it is possible to complete the process in one go on the CNC machining center, it can reduce the time for repeated clamping and the errors caused by positioning;

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

5. Depending on the different sequence arrangements of the processes, the diameters of the machining tools vary from large to small;

6. By organizing the same fixtures and jigs together, the cost of making fixtures and the time for repeated clamping can be reduced;

7. For thinner products, rough machining should be carried out first, followed by a period of placement before fine machining, which can reduce deformation;

8. For products that undergo heat treatment, rough machining should be carried out first, leaving a margin for heat treatment, and then they should be returned for finish machining;

9. For products requiring surface treatment (such as oxidation, electroplating, powder coating, etc.), allowances should be made during processing based on the corresponding surface treatment to ensure that the dimensions meet customer requirements after surface treatment.

10 .  The parameter setting should prioritize the main parameters before the auxiliary ones.

CNC machining involves a wide range of materials and processes, which can lead to various issues during the machining process. Only with accumulated experience can one handle these issues with ease.
