It’s been estimated that a tool with a run-out of 50% of the tool’s chip load will reduce its tool-life by 40%.
That means that a 1/8” tool with a 0.00019” chip load per tooth will lose 40% of its tool-life with a run-out of less than 0.0001”.
Excessive and inconsistent run-out from a properly setup ER collet chuck assembly typically occurs due to friction build-up between the 30° face of the collet and the collet nut.
As the collet nut presses down and turns against the 30° face of the collet, the collet face will tend to twist with the collet nut, distorting the shape of the collet. This radial distortion negatively affects tool run-out sine the collet bore is not longer straight.
Parlec’s new P3 ER collets have a special anti-friction coating on the 30° face that dramatically reduces friction at this critical connection.
- Improved tool runout
- Longer tool-life
- Less frequent tool changes
- Improved surface finishes
Other Parlec P3 collet advantages:
- 3 micron T.I.R
- Fewer slots that standard collets making them more rigid – in the cut!
- Special slotting seal for coolant up to 2,000 PSI
