Key Points of Milling

In the actual production of CNC Machining and milling, including machine tool setting, workpiece clamping, tool selection and other application skills, this paper briefly summarizes 17 points of CNC Machining and milling:

1. Power capacity

Check the power capacity and machine rigidity to ensure that the machine tool can use the required milling cutter diameter.

2. Workpiece stability

Workpiece clamping status and considerations.

3. Suspension

The tool overhang on the spindle is kept as short as possible during CNC machining and milling.

4. Choose the correct pitch of milling cutter

Use the correct pitch of the milling cutter suitable for the working procedure to ensure that there are not too many blades involved in CNC machining and milling, otherwise it will cause vibration.

5. Cutting Cutter

For narrow custom CNC Milling parts or gap milling, ensure that there are enough blades to eat.

6. Blade groove selection

Use positively grooved indexable inserts as far as possible to ensure smooth cutting and minimum power consumption.

7. Use the right feed

By using the recommended maximum chip thickness, the correct feed of the blade is ensured to achieve the correct cutting action.

8. Cutting direction

Use forward CNC machining and milling whenever possible.

9. Custom CNC milling parts considerations

Material and configuration of the custom CNC milling parts and quality requirements of the surface to be machined.

10. Selection of Blade Material

The groove and material are selected according to the material type and application type of the custom CNC milling parts.

11. Vibration-absorbing CNC machining and milling cutter

For the long overhang which is more than 4 times the diameter of the tool, the vibration trend will become more obvious, and the productivity can be significantly improved by using the vibration-absorbing tool.

12. Principal Deviation Angle

Choose the most suitable main deviation angle.

13. CNC machining and milling Cutter Diameter

Choose the right diameter according to the width of the custom CNC milling parts.

14. CNC machining and milling cutter position

Correct positioning of milling cutter.

15. Cutting in and out of CNC machining and milling cutters

It can be seen that through arc CNC machining and milling, the chip thickness is always zero when the tool is withdrawn, so that higher feed and longer tool life can be achieved.

16. Coolant

CNC machining and milling can be better performed only when coolant is used as necessary, and usually when coolant is not used.

17. Maintenance

Follow the tool maintenance advice and monitor tool wear.
