CNC vertical lathe machining is a high-precision machining method that can accurately manufacture workpieces of various shapes. However, in the process of using CNC vertical lathe, we often encounter the problem of rough surface of some workpieces. So, what is the reason why the workpiece processed by CNC vertical lathe is rough?

First of all, the accuracy of CNC machining is affected by many factors, such as the initial state of the workpiece, tool selection, processing parameter settings, etc. If there is a problem in any of these links, it may cause the surface of the processed workpiece to be rough. For example, if the tool is severely worn or used improperly, it is easy to cut cleanly and form burrs and texture, thus affecting the appearance and performance of the workpiece.

Secondly, during CNC machining, the contact between the tool and the workpiece is very important. If the contact is uneven or vibration occurs, the surface of the processed workpiece will become rough. At the same time, the feed speed and cutting speed of the tool also need to be considered comprehensively. If the speed is set improperly, it will also cause the workpiece to be rough.

Finally, the selection and use of cutting fluid during processing is also one of the factors that affects the surface roughness of the workpiece. If the properties of the cutting fluid do not meet the requirements or are used improperly, it will cause overheating and knife jamming during the cutting process, thus affecting the surface finish of the workpiece.

Therefore, in order to solve the problem of rough workpieces processed by CNC vertical lathes, it is necessary to carefully analyze each link of processing to identify the problem and solve it. At the same time, strengthening the learning and mastery of CNC machining technology can also better avoid the problem of rough surface of workpieces.
