In the CNC vertical turning process, the roughness of the workpiece is a very important indicator, which directly affects the surface quality and processing efficiency of the workpiece. Therefore, how to improve the roughness of the workpiece is one of the skills that every CNC vertical lathe engineer must master.
1. Reasonable selection of cutting technology
The cutting process is one of the important factors affecting the roughness of the workpiece. In the actual application process, we need to choose the appropriate cutting process based on factors such as the hardness of the workpiece material, cutting speed, feed amount, and cutting depth. Under normal circumstances, adopting higher cutting speed and feed rate can improve the processing efficiency to a certain extent, but it will also lead to an increase in the surface roughness of the workpiece.
2. Select appropriate cutting tools
The selection of cutting tools is also one of the important factors affecting the roughness of the workpiece. Cutting tools are faced with high-speed rotation and frequent contact with cutting materials, so it is very important to choose high-quality tools. If poor quality cutting tools are used, tooth surface wear, deformation or failure will easily occur, which will lead to unstable cutting forces and further affect the surface roughness of the workpiece.
3. Strengthen the cutting fluid on the tool to reduce friction
Since the high-speed friction between the material and the tool will cause melting and deformation of the material surface, causing more burrs and other defects on the workpiece surface, the use of cutting fluid can effectively reduce friction and heat accumulation, thereby controlling it to a certain extent. The size of the workpiece surface roughness.
4. Pay attention to the adjustment of cutting parameters
In the actual machining process, the adjustment of cutting parameters is the key to improving the roughness of the workpiece. Setting appropriate feed and cutting speed can make the machining process more stable, thereby reducing scratches or scratches on the tooth surface and improving the quality and roughness of the workpiece surface.
Improving the roughness of CNC vertical lathe workpieces requires strengthening the learning and practice of cutting technology. By constantly adjusting and improving the cutting process, selecting appropriate tools, making good use of cutting fluids, and adjusting cutting parameters, the surface finish of the workpiece can be improved, ensuring the stability and consistency of the processing effect, thereby giving full play to the capabilities of CNC vertical lathes.
