Fixture selection

Views:7     Author:Site Editor     Publish Time: 2018-07-28      Origin:Site

          The characteristics of CNC machining put forward two basic requirements for the fixture: one is to ensure

that the coordinate direction of the fixture is relatively fixed with the coordinate direction of the machine tool; 

the other is to coordinate the dimensions of the part and the machine coordinate system. In addition to this, 

focus on the following points.


  1. For single-piece small-volume production, it is preferred to use combination fixtures, adjustable fixtures and

    other common fixtures to reduce production lead time and save production costs.

2.In CNC machining, fixtures with precise positioning, strong clamping force and high precision should be used, 

   which will be more conducive to the processing and production of workpieces.

3. The loading and unloading of parts and components should be fast, convenient and reliable, so as to shorten

    the pause time of the machine and reduce the auxiliary time.

4. In order to meet the precision of CNC machining, fixture positioning and clamping accuracy are required.

5. The components on the fixture shall not interfere with the machining of the surface of the part by the 

   machine tool, that is, the fixture shall be open, and the positioning and clamping components shall not 

   affect the machining pass (such as production collision).

6. In order to improve the efficiency of CNC machining, Jingzuan intellingent manufacturing  Co., Ltd. 

   reminds everyone that large-scale parts can be processed by pneumatic or hydraulic clamps and multi-station clamps.
