How to ensure the accuracy of cnc processing mass production?

by Xueqin Yang cnc machining

Precision is among the important indications for evaluating the machining performance of cnc machining factory. Machining accuracy and also machining error have a terrific effect on the top quality of the work surface. Exactly how to ensure the precision of the item when it is refined in huge amounts?

 

Cnc machining In the mass production of automatic production, the loved one position of the maker tool, fixture, workpiece and also device can be adjusted ahead of time to obtain the called for dimension to obtain the function of guaranteeing set machining precision. To make certain the accuracy of the item when machining the work surface in huge quantities. The following modifications have to be made:

 

1. Control the thermal deformation of the procedure

The cnc machining center is a high-speed cutting processing equipment. A big amount of heat is produced throughout the processing. The warmth generation of the warmth resource should be reduced as well as the warm resource need to be separated, as well as the heat therapy procedure for eliminating the interior tension ought to be included.

 

2. Lower the transmission chain transmission mistake

The transmission system must keep the variety of transmission parts small, the transmission chain is short, as well as the transmission precision is high. Using the down-speed transmission is an essential way to ensure the transmission precision, as well as the closer to the end of the transmission pair, the smaller sized the transmission proportion; the accuracy of completion item ought to be high. For various other transmission components.

 

3. Lower tool wear

The machining device should be re-grinded before the sharp wear stage, and the unique cutting oil must be utilized for sufficient lubrication. The tool product must meet the process requirements.

 

4. Improve the rotation precision of the bearing

High-precision rolling bearings, multi-oil vibrant pressure bearings as well as hydrostatic bearings are readily available. At the exact same time, the precision of the bearing devices is improved, such as boosting the machining accuracy of the support hole of package and also the pin journal, to make sure that the spindle turning accuracy is not reviewed the workpiece.

 

The dimension of the machining error reflects the degree of machining accuracy. The greater the error, the reduced the machining precision. The smaller the error, the higher the machining accuracy. In order to ensure the accuracy of the work surface, the machining error is minimized. The above 4 actions can attain precision control in mass production of cnc processing, thus managing the machining mistake within an affordable array.
