When Sandvik Coromant announced that its new PrimeTurning process could cut cycle times in half, some were skeptical. Even more so when the cutting tool maker said that it would result in better tool life and surface finish too. But the company has good data on a number of applications and can prove the benefits of the process.

Will you get that kind of improvement in all parts? No, not at least yet. But in well supported turning applications where you are removing a lot of metal, or in high volume applications where you are moving a lot of parts, the process can well result in dramatic improvements in output and productivity.

The key is the ability to feed the turning tool in any direction: toward or away from the chuck in turning operations, and up or down in facing operations. A very low lead angle on the insert allows you to take much more aggressive cuts. And the ability to feed away from shoulders eliminates the chip-jamming problems typical of conventional turning.
