What issues should be paid attention to when choosing tools for CNC lathes?

 After the model selection of the CNC lathe is completed, the tool is selected. The tool is the tool that executes the completion of the workpiece, while the CNC lathe uses the tool to complete the processing effect. The selection of the tool is an important step after the model selection of the CNC lathe. Why do you say this? The main reason is that the different materials, characteristics and accuracy of the workpiece are different, so the selection of the tool needs to consider the following aspects.

Factors to consider when choosing a tool:

  • 1. The types of materials to be processed: non-ferrous metals (copper, aluminum, etc.) and ferrous metals (steel, cast iron, etc.) have different cutting performance, and should be treated differently when choosing tools. Non-ferrous metal materials are soft and all kinds of tools can be processed, but this kind of material is tough and should have a higher cutting speed during processing, otherwise the surface roughness will be reduced. Ferrous metals have high strength, high brittleness, and easy chip breaking. After heat treatment, there will be a big difference in hardness. Generally, cemented carbide tools should be used for processing.
  • 2. The heat treatment state of the material: the hardness and strength of the metal material will be greatly changed after the heat treatment, so it should be treated differently when determining the tool. The blades provided by tool manufacturers can be divided into categories that are suitable for high speed, high hardness and powerful cutting. Different types of tool materials have different affinity for non-ferrous and ferrous metals due to their different components, and they need to be treated differently.
  • 3. Production batch and production conditions: The production batch will affect the economic life of the tool. Mass production should ensure the production cycle and production efficiency, and the durability of the cutter must be basically in line with the production cycle. The cutting blade should be able to withstand the cutting load, that is, the blade is required to have strength and thermal shock resistance. The large-size blade has high strength, strong processing ability, high processing efficiency, and high price.
  • 4. The geometry of the workpiece: the use of suitable tools for processing different parts of the workpiece can greatly improve its processing efficiency.

The above analysis is based on the nature and characteristics of the processing material to choose the tool. Of course, when we choose the tool, we will also pay attention to the price and quality of the tool and the fact that there are many cases of tool collapse during production and processing. These are all things we need to consider. Choose better quality tools at the same price.

Make preparations beforehand and select the tools. When we process the workpiece, the efficiency will be improved, and we will not waste time because of the wrong tool selection.
