In the past climb milling was seen as bad practice, leading to broken cutters and spoiled work, but the advent of CNC and minimal backlash machines has seen it become a preferred approached under these circumstances.
Climb milling remains a risky strategy on machines where the slides are liable to sudden movement under the forces of a climb-milling cut.
If you have ball-screws, anti-backlash feed-nuts, a preloaded table or your machine has been carefully adjusted so that the cutter cannot grab the table, then climb milling has advantages, especially with carbide cutters. One of these is extended cutter life. With the kind permission of Sandvik Coromant, we are able to share a copy of their publication 'Why Climb Mill'.
