Ballnose Cutter Adds Cutting Edge for Fast Feed Rates
Designed for the production of homokinetic joints of hardened steel in automotive applications, Mapal’s CPMill ballnose milling cutter has been updated for efficiency in pre-machining (soft milling).
Designed for the production of homokinetic joints of hardened steel in automotive applications, Mapal’s CPMill ballnose milling cutter has been updated for efficiency in pre-machining (soft milling). Instead of four cutting edges, the updated solid carbide cutter has five, and its highly spiraled geometry ensures optimal chip removal. In addition to the base substrate, the coating has also been improved. The CFS interface eases milling head changes. According to the company, the precise tuning of the taper and face contributes to a concentricity of ≤5 microns, high rigidity and consistent work quality.
The company also says that higher cutting and feed rates mean machining time with this cutter can be reduced, increasing part production rates by as much as 12 percent without changing machine capacity or other equipment investments. In addition, the cutter provides a longer service life than the previous model.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
The right choices in tooling and technique can optimize the thread turning process.
