In the actual production of milling, including machine tool settings, workpiece clamping, tool selection and other aspects of application skills, today we briefly summarized the main points of milling, which is worth a look!
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 conditions and considerations.
3. Overhang
Make the tool overhang on the spindle as short as possible during machining.
4. Select the correct milling cutter pitch
Use the correct milling cutter pitch suitable for the process to ensure that no too many blades participate in the cutting, otherwise it will cause vibration.
5. Cutting tool
When milling narrow workpieces or with gaps, ensure that there are enough blades to feed.
6. Blade slot type selection
As far as possible, use an indexable insert with a front angle groove to ensure a smooth cutting effect and minimum power consumption.
7. Use correct feed
By using the recommended maximum chip thickness, ensure the correct feed of the used blade to achieve the correct cutting action.
8. Cutting direction
Use straight milling as much as possible.
9. Part Considerations
Workpiece material and configuration, and quality requirements of the surface to be machined.
10. Blade material selection
The groove type and material are selected according to the material type and application type of the workpiece.
11. Vibration reducing milling cutter
For longer overhangs that are more than 4 times the tool diameter, the vibration trend will become more obvious, and the use of damping tools can significantly improve productivity.
12. Main deflection angle
Select the most appropriate main deflection angle.
13. Milling cutter diameter
Select the correct diameter according to the width of the workpiece.
14. Milling cutter position
Position the milling cutter correctly.
15. Milling cutter cut in and cut out
It can be seen that through arc cutting, the chip thickness is always zero when the tool is retracted, so that higher feed and longer tool life can be achieved.
16. Coolant
Use coolant only when you think it is necessary. In general, milling can be performed better without coolant.
