Thermo Plastic - 1. This cutting condition table shows the standard values. When machining, it is recommended to use the program created by the NC program creation tool “ThreadPro”. 2. Please select “Continuous” as the path type of ThreadPro. 3. Please use water soluble coolant unless there is pre-hole made by casting or drilling. 4. When machining magnesium please refer to the coolant oil manufacturer’s specification for recommended oil. Please also properly dispose of the cutting chips to prevent fire hazards. 5. Please adjust the cuting conditions depending on the rigidity of the machine, tool holder, and workpiece clamping. 6. Tool vibration should be kept at a minimum level to ensure highest thread accuracy. 7. Select a higher feed rate for larger diameter tooling and a lower feed rate for smaller diameters. 8. The tool is left-hand cutting - program the spindle for counterclockwise rotation.
Note Bottom shape of finished hole is as depicted in the right picture. Please make sure that it is acceptable based on the cutting instruction in advance.
