How to Regulate Cutter Speed of a Machine Milling Vertical
A machine milling (vertical) is built for precision cutting. Its head is designed to slide up and down instead of horizontally, giving way to a more secure worktable. In order that the cutting accuracy of a vertical mill is preserved, there are several factors governing cutter speed that operators should look out for.
The type of metal cutter that is screwed to the machine largely influences its speed. Toothed cutters, or positive rakes, are generally run at higher speeds than radial cutters because they cut more freely and are sharper. Also, they receive little resistance from the surface they are working on, allowing the positive rakes to withstand higher speed.
Angle cutters, on the other hand, must be run at lower speeds. It is easier to cut vertically than at an angle. For this reason, the speed of the vertical machine should be adjusted based on the cut to be made.
