CoroPlex® YT
All-directional Y-axis turning
Requirements
Machine
NC control
CAM programming
Application tips
Entering angle: CoroPlex® YT with CoroTurn® TR
• Components with pockets and cavities
• Optimal entering angle: 60–90°
• If possible, keep tool perpendicular to feed direction
• Avoid small and large entering angles
Entering angle: PrimeTurning™
• Shafts, flanges and components with undercuts
• Optimal entering angle: 25–30°
• Avoid small and large entering angles
Entering angle: CoroPlex® YT with CoroTurn® 107
• Components with pockets and cavities
• Use small depth of cut, recommended ap 10–15% of insert diameter
• Program feed rate based on constant chip thickness
• Use non-linear turning methods with smooth entry and exit
Tool length vs. workpiece diameter
Tool length limits workpiece diameter.
Recommendations
Entering angle
- The entering angle has a large impact on chip control and notch wear
- Avoid too small and very large entering angles
- Facing to centre with large entering angle drastically shortens tool life
- If a large entering angle can be avoided, use ap below nose radius.
