FAHRION provides the largest range of forms and executions of collets DIN 6499/ISO15488 (ER/ESX) for different applications)

Precise - FAHRION collets DIN6499/ISO15488 - Form B (ER/ESX) set new standards of concentricity and repeatability, which is 5 µm for the types GER11 up to GER40

Rigid - 12 slotsare sufficient in order to reach the required collapse to DIN6499/ISO15488 ISO15488.
This is possible because of a special steel produced for us and a particular harmonized heat treatment. Compared to 16 slot collets, our collets have less tendency to distort

Saving - all edges are not only deburred, but additionally rounded, which is a prerequisite to protect the inner cone of the collet chuck from marks. This process is important to guarantee a consistent repeatable high accuracy.

Increased rigidity and clamping forces, improved grip, higher precision and system concentricity, enhanced resistance to corrosion
for GER-B, GER-HP, GER-HP+, GER-D, GER-DD due to super-finished execution

Precise - Constant concentricity and repeatable accuracy 3µm
at distance 3xD (max. 50 mm). Pure axial clamping of the collet by means of a clamping sleeve and clamping nut result in no torsion moments.

Simple - Clamping by means of a hexagon T-Key - Opening by means of our patented ejection mechanism (no eccentric) permits a quick and easy tool and collet change on the machine spindle or in your hand. The collet is only shifted axially. There are no radial forces to have a negative influence on the concentricity.

Unique - Patented mechanical clamping wedge clamping forces up to 300.000 N can be produced by hand, which increase with higher speeds and at the same time the mechanical construction ensures high durability.

The Precision Collet HP+ has a surface roughness of Rz 1.6µm on the external contour, which is a prerequisite for generating the high clamping forces. Because of the high forces the individual elements form a concentric unit with exceptionally low runout and high stiffness.

FAHRION Precision Collet HP+ makes possible the highest level of reproducible accuracy and damps potential vibrations from the machine
