Tapping Collets

P.C.M Tapping Collets(ET1-1-12, 16, 20, 25, 32) are applicable to our EY Tool Change Adapter and EY Chuck with Straight Shank.

The following programming for tapping process is remmended:fast approach to the work piece, then tapping feed with approximately 95％ of the pitch value, which is 20-30％ of the compensation stroke(E), when the spindle rotation and feed movement are simultaneously reversed. Return feed must be made with 100％ of the pitch, which maintains the sleeve of tapping collect in compensation stroke up to the tap disengagement;quick return can then be programmed with usual stroke security. The relatively long axial compensation assists easy programming. When tapping with very high speed, an appropriate programming compensation may be necessary to balance the differences of inertia between the spindle and the feed movement on reverse.

Coolant-Sealing Back-up Screws

These back-up screws have a seal made from urethane material, resistable both to water-soluble coolant and to oil coolant, which enables machining without decreasing in coolant supplying pressure.

For the drills having oil holes for coolant, being used to the EY chucks, this coolant-sealing back-up screw can be used in place of the standard back-up screw, for sealing the coolant oil coming from the rear side.

These Coolant Sealing Back-up Screws are capable of sealing for oil-coolant drills having hole diameter 5 to 32mm.
