Three countermeasures to improve the machining accuracy of drill cnc machine from exoltechcom's blog

drill cnc machine is an automatic machine with high precision and high efficiency. However, in the process of processing, it will inevitably be affected by a variety of factors, making its processing precision produce a certain deviation, and bring some inconvenience to production and life. How to improve the machining accuracy of inclined bed machine tool is a matter of great concern to CNC people.

In the machining process of the machine tool, the precision of the parts processed directly affects the quality of the product, some mechanical parts and precision equipment parts of the processing accuracy requirements are very high, improve the machining accuracy of the CNC machine tool is the key to solve the problem. Through extensive research and analysis, it is concluded that there are roughly the following ways to improve the machining accuracy of CNC machine tools:

First, control the original error to improve the machining accuracy

In the process of drill cnc machine processing, the error itself is inevitable, there is an inevitable error between the machined parts and the CNC machine tool, and this certain error is called the original error. Therefore, in order to improve the machining accuracy of CNC machine tools, controlling the original error of CNC machine tools is one of the important countermeasures. The possibility of the original error should be analyzed systematically, and the corresponding improvement measures should be formulated according to the cause and type of the error.

Second, reasonable design of the core parts of the machine tool to avoid positioning errors

The positioning accuracy of the machine tool has an important impact on the accuracy of the parts, and the core components that affect the positioning accuracy of the machine tool, such as the straightness and levelness of the feed system, guide rail, work surface, etc. When designing CNC machine tools, it is necessary to reasonably choose the core components, such as when selecting the ball screw widely used in the machine tool, the accuracy of the ball screw should be fully considered, and the more mature ball screw technology should be selected and installed.

Third, improve the processing accuracy through real-time monitoring technology

With the continuous improvement of numerical control technology, the drill cnc machine machining process real-time monitoring, timely adjustment of the error in the process of processing, and processing of each link of the error data collection, and feedback to the control terminal, and through the error data to take the corresponding error compensation mechanism, timely error compensation. It can effectively improve the machining accuracy of parts.
