climb milling

In climb milling, the work moves with the rotation of the cutter.

Reverse the cut direction to convert conventional milling to climb milling.

If the workpiece is moving the same direction as the tool rotation, this is called climb milling.

Generally speaking, conventional milling optimises metal removal whilst climb milling produces a better surface finish.

Features such as machine reverse allow you to control whether to perform climb milling or conventional milling depending upon the nature of your material and tooling.

Climb milling (right): Each tooth engages the material at a definite point, and the width of the cut starts at the maximum and decreases to zero.

However, climb milling can apply larger loads to the machine, and so is not recommended for older milling machines, or machines which are not in good condition.
