High-quality high-speed CNC machining technology requires the coordination of cutting strips and tool selection to ensure the efficiency and longevity of the machine tools, thereby achieving greater effectiveness. The rigidity standards for the machine body are higher, and the rigidity requirements for the tool holder and spindle are also elevated. The drive unit in cutting equipment should have high rotation speeds, and the axial distance between the tool and spindle should be maintained by the spindle, pressure, and cooling devices.
2.Cutting Tool Technology
Attention must be given to the installation, positioning accuracy, and assembly precision of the tool holder. During machining, maintaining high speeds and preventing tool damage due to improper parameter selection is essential. Cutting tool materials should be chosen based on specific requirements. High-speed tool holders are suitable for high-speed cutting, featuring rapid expansion and contraction characteristics. Moreover, during high-speed cutting, the tools must withstand high temperatures, high pressure, and external environmental impacts.
