Main methods to improve the precision of CNC machining of mechanical molds
May 17, 2021

The application of numerical control processing technology enables it to be fully applied in all aspects of mechanical mold manufacturing, and the production and manufacturing quality, accuracy, and efficiency are fully improved, and the processing methods are summarized and analyzed.


1. Application of technology for precise control of geometric errors. As a transmission component, the machine tool spindle affects the relative position of the workpiece to a large extent, mainly affecting the flatness of the workpiece surface, resulting in a certain error in the workpiece. Effectively avoid the root causes of errors. Maintain the assembly spindle, spindle, etc. for effective lubrication; use new wear-resistant material processing tools to effectively reduce the wear of the tool and increase its service life.


2. The influence of heat and force on accuracy and control technology. In the specific operation process, it is necessary to select more practical tools, adjust the cutting depth, and adopt scientific cooling methods to effectively suppress the thermal deformation, to further improve the accuracy of the overall processing technology. Use cooling lubricants to pre-cool the non-machined surface of the workpiece to effectively reduce the influence of heat and force on the machining accuracy to a greater extent.


3. Apply the control technology of machining operation accuracy. During the operation, when clamping and adjusting, a fixed fixture or a more suitable auxiliary tool corresponding to it should be selected to effectively reduce the operating error and improve the overall accuracy of the workpiece. Reduce accuracy errors caused by human factors.
