Tool surface cutting direct participants to understand and become familiar with the processing status of the tool is the right choice tool premise. Tool selection, tool factors to consider, such as material, coating, Groove, length and diameter outside, also need to take full account of the relevant processing factors, such as processing materials, cooling method, spindle rigidity and fixture stability . In this case, we use a non-standard tool shown in Figure 3, thereby reducing a workpiece clamping time, reduce the processing time of the machine. While using our latest products carbide cutting tools, greatly improving the processing speed, thereby significantly reducing the processing time.
