1.ER Collets are applied for a variety of processing,including drilling, milling,tapping&grinding.
2.material: 65Mn er collets. standard: DIN6499B
3.hardness:HRC 44-48. 4. full size: ER8,ER11,ER16,ER20,ER25,ER32,ER40,ER50.
Features:
Widely used in boring, milling, drilling, tapping, CNC, sculpture and other processing operations, also can be supported used with the holder of CNC tool.
Big clamping force, wide clamping range, high accuracy.
The correct methods of mounting the collet nut:
1. Put the chuck into the pressure cap, gently turn the clamp spring, when eccentric portion of the pressure cap recessed clamp spring groove. Along the arrow
direction and use equal force to push clamp spring, can mount pressure cap.
2. Put the clamp spring and cap all together installed on the chuck body or spindle. Insert into the clamping hole after wipe the cylindrical shank, use a wrench to
tighten the pressure cap, until clip firmly the tool before use.
(Note : Avoid fastening pressure cap that not installed tool, to avoid damage the clamp spring)
