Summary: We are proud to supply the Fahrion Range of ER equipment which includes probably the best ER collets. These are supplied as standard to 6 micron accuracy for ER11-ER40, at competitive prices.
Tests have shown, when using carbide tools Fahrion ER Collets can increase tool life by up to 150%.
Precise: FAHRION Collets DIN ISO 15488 -B (ER/ESX) set the standard of concentricity and repeatability, which is 5 µm for the types ER11 up to ER40.
Rigid: 12 slots are sufficient in order to reach the required collapse to DIN ISO 15488 . 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 these ER collets due to super-finished execution (see picture above)
