Machining center: the performance of the tool
The tool is a tool used by the machining center for cutting. The tool must have very good performance to process the workpiece smoothly, otherwise it will cause great trouble in production. Therefore, the tool material must have the following capabilities.
1. High hardness
The tool material must have high hardness, at least higher than the hardness of the processed workpiece, otherwise the workpiece will not be processed, and it will directly cause the wear of the tool.
2. High temperature resistance
In the high-speed machining center, the high-speed rotation of the tool and the workpiece contact processing will produce a certain high temperature, so the tool must have high temperature resistance.
3. Good thermal conductivity
The tool must have good thermal conductivity, otherwise the temperature generated during the process cannot be derived, which will directly cause the tool to wear too quickly at high temperatures.
4. Strong toughness
The tool must have sufficient toughness, otherwise problems such as easy fracture in the machining center will occur.
5. High wear resistance
The tool must have high wear resistance, otherwise the tool will wear for a long time, the tool will wear too quickly, increasing the cost.
6. Small chemical reaction
The tool must have a small chemical reaction. We all know that metals at high temperatures will chemically react, so we must choose a tool material with a small chemical reaction.
The tool is a very important tool in the high-speed machining center. It is the only thing that can contact the workpiece. The spindle is installed with a tool that rotates and contacts the workpiece for high-speed processing. The tool material is not a general material. use.
