How to Use a Roughing End Mill?

By running a roughing end mill at a desired speed and feed rate, you can save time and assure that the mill will not break under pressure.

1. Insert the roughing end mill into the holder. On a CNC machine, the holder will be large and will have an adjustable screw on the side. Line the flat area on the shaft with the crew and use an Allen wrench to tighten. When using a manual mill, insert into the collet that most closely fits the end mill.

2. Teach the roughing end mill according to the procedure that your CNC uses. Many CNC machines allow you to go into a teach mode, in which the spindle grabs the tool to be teached and lowers it slowly onto a probe.

3. On a manual mill, start the spindle at a slow speed and lower the roughing mill with the Z axis handle to the desired location. Depending on the material you are cutting, you want to adjust the speed accordingly.

4. Start the roughing process on a CNC mill. The machine will grab the roughing end mill from the tool turret and slowly bring it to s start position above and beyond the metal to be cut. Watch as the machine makes the first pass to make sure that it is roughing properly and that there is not excess pressure on the tool, because it may break if it is spinning too slowly while being fed too quickly.
