The importance of CNC technology


 First, the basic principles of positioning and installation

When machining parts on CNC machine tools, the basic principle of positioning and installation is to reasonably select the positioning reference and clamping program. The following points should be noted when selecting:

1. Strive to unify the design, process, and programming calculations.

2. Minimize the number of chucking operations. After all positioning fixtures are completed, all surfaces to be machined are machined.

3, to avoid the use of manual adjustment of the manual processing program to give full play to the effectiveness of CNC machine tools.

Second, choose the basic principles of the fixture

The characteristics of NC machining put forward two basic requirements for the fixture: First, it is necessary to ensure that the coordinate direction of the fixture and the coordinate direction of the machine tool are relatively fixed; the second is to coordinate the dimensional relationship between the parts and the machine tool coordinate system. In addition, consider the following points:

1, when the parts processing volume is not large, it should try to use combination fixtures, adjustable fixtures and other universal fixtures, in order to shorten the preparation time and save production costs.

2. Consider the use of special fixtures in batch production and strive for a simple structure.

3, the loading and unloading of parts should be fast, convenient and reliable to shorten the pause time of the machine tool.
