CoroTurn® Prime and PrimeTurning™
Revolution In TurningIntroducing a revolution in turning with a new product that is more than a tool, it is a complete new way of turning. PrimeTurning™ is the industry’s first “all-directional turning” solution that offers improved machining flexibility, and productivity gains over conventional turning. This revolutionary concept is comprised of a new turning method, dedicated CoroTurn® Prime tools, and a code generator.
All-Directional ToolingPrimeTurning operates in multiple directions. The tool moves toward the chuck in the Z axis as it cuts in a traditional manner, but the tool can also “go in reverse” moving away from the chuck as it cuts. The tool can cut “up from” or “down to” the part centerline in the X axis for facing or shoulder cutting. Each insert can rough, finish or profile by cutting in either direction. View Tools »
Productivity IncreasesIn some applications, operators achieve productivity increases of more than 50 percent by using PrimeTurning rather than conventional techniques.
Small Entering Angles
The small entering angle (KAPR) will create a thin and wide chip, which spreads the load and heat away from the nose radius. This results in increased tool life.
Entering and lead angles:
A-type KAPR = 30°, PSIR = 60°
B-type KAPR = 25°, PSIR = 65°
Efficient Edge Utilization
CoroTurn Prime inserts have three edges per corner. One edge each for longitudinal, facing, and profiling, distributing the wear over a longer edge and not just the insert tip. It also moves heat away from the cutting zone, helping inserts last substantially longer.
No Chip Jamming
The PrimeTurning method enables turning away from the shoulder, eliminating the possibility of chip jamming commonly observed in conventional turning. This results in an excellent surface finish and
avoids tool damage.
