CNC vertical lathe is an efficient and high-precision machining method that can meet the processing needs of workpieces of different materials. However, in practical applications, cutting vibration problems are prone to occur due to the influence of different processing conditions, materials and other factors. Cutting vibration will affect factors such as machining accuracy, surface quality, and tool life, so measures need to be taken to reduce cutting vibration. The following will introduce some methods for reducing cutting vibration in CNC vertical lathes.

1. Select appropriate cutting parameters

Cutting parameters have a great influence on cutting vibration, so appropriate cutting parameters need to be selected based on specific workpiece materials, hardness, shape and other factors. Generally speaking, reasonable selection of parameters such as spindle speed, feed speed, cutting depth and cutting angle can effectively reduce cutting vibration.

2. Use appropriate cutting tools

Choosing the right cutting tool is also key to reducing cutting vibration. Generally speaking, cutting tools with good rigidity, appropriate cutting angles, and a large number of cutting edges should be used as much as possible to reduce the occurrence of cutting vibration. At the same time, the shape and material of the cutting tool must also be adapted to the workpiece being processed.

3. Use appropriate clamping methods

The way and accuracy of clamping the workpiece is also one of the factors affecting cutting vibration. Using appropriate clamping methods can prevent the workpiece from being twisted or deformed during the cutting process, thereby reducing the occurrence of cutting vibration.

4. Choose appropriate cutting fluid

Using appropriate cutting fluid during machining can also reduce the occurrence of cutting vibration. Cutting fluid can cool the cutting area, lubricate the cutting surface and reduce friction, thereby reducing the occurrence of cutting vibration.

5. Optimize CNC programming

Reasonable writing of CNC programming is also an important means to reduce cutting vibration. During the programming process, factors such as workpiece shape, cutting requirements, and cutting parameters must be fully considered, the cutting path and cutting sequence should be optimized, and unreasonable operations such as repeated cutting and overload cutting should be avoided.

To sum up, there are many ways to reduce cutting vibration in CNC vertical lathes, and comprehensive measures need to be taken from multiple aspects. It is believed that as long as the above methods are strictly followed, cutting vibration can be effectively reduced and machining accuracy and efficiency improved.
