numerical control Gantry milling machine When processing, K For some mechanical parts, in addition to easy to cause workpiece deformation in machining, it will also cause workpiece deformation due to various unpredictable reasons after machining. Only knowing why the workpiece will deform after machining can we better improve the quality of machining workpieces. Yuntuo machining focuses on large-scale machining, and continuously processes the workpiece after machining Why does it deform. Small editor for numerical control Gantry milling machine Summarize the experience of machining.

one The material of machined workpiece will produce bending deformation when cutting, which is stainless steel material;

two When the center of the workpiece is hollowed out, the stress and deformation will occur;

three Deformation caused by excessive cutting amount or high temperature during machining;

four The workpiece is annealed without stress treatment;

five Deformation caused by improper processing technology.

 

numerical control Gantry milling machine The solution of workpiece deformation after machining

one Proper and scientific aging treatment should be carried out for the material of the workpiece to reduce the stress and deformation of the workpiece;

two Setting appropriate machining allowance and adopting the principle of a small number of times for slow machining, so as to reduce the deformation caused by excessive cutting amount or high temperature;

three For curved surface machining, it is necessary to make suitable fixture to balance the clamping force of the workpiece, so as to reduce the deformation of the workpiece.

  The above is about Gantry milling machine Of course, these solutions can not reduce the deformation of the workpiece, but can make the deformation of the workpiece smaller to a certain extent. In the process of mechanical parts processing, the above solutions can be used to solve the deformation problems that you encounter, which can also play a key role in improving the quality of processed parts. sh-mjt.com
