Product information "Precision collets ER20 (1-12,7 mm)"

The industrial collets from AMB are manufactured under the highest quality standards in Germany.


The ER20 collet is the further development of the standard collet system. The distribution of the clamping forces is much more uniform and precise, which is why a higher concentricity repeatability is achieved.

.

A high runout accuracy of the tool is always characterized by the perfect interaction of the angle and the surface of the collet holder in the milling motor, the union nut and the collet itself. 


Often, cheap products are chosen for collets whose angle and surface tolerances are poor. Here a high quality concentricity is not possible, despite the fact that a concentricity of a few Mhy tolerance is advertised.

.

When using the AMB system of milling motor, collet and union nut, the system runout tolerance, measured at a distance of 20mm from the union nut, is max. 0.03mm.


 

FAQ

F: Was für eine Rundlauftoleranz hat diese Spannzange? A: 0,03mm

F: Im Netz gibt es günstigere Spannzangen aus Asien mit einer Genauigkeit von 4Mhy? A: Papier ist leider sehr geduldig. Wir haben dutzende Spannzangen verschiedener Hersteller vermessen. Die Steuung der Toleranzen dieses Spannzangen beträgt häufig das 10-fache des angegebenen Wertes. 

F: Was unterscheidet das ER16 System vom Standard? A: Das System der Standard Spannzange wurde in den 80-er Jahren maßgeblich von Kress entwickelt wird heute noch von vielen Wettbewerbern verwendet. Der Hauptunterschied ist die Rundlauf-Wiederholgenauigkeit. diese ist beim ER16 System 3x besser als beim Standard System.

F Was bedeutet Rundlauf-Wiederholgenauigkeit? A: Der Unterschied in der Rundlauftoleranz vom Einspannen eines Werkzeuges zum Nächsten.

F: What is the runout tolerance of this collet? A: 0.03mm

.

F: On the net there are cheaper collets from Asia with an accuracy of 4Mhy? A: Unfortunately, paper is very patient. We have measured dozens of collets from different manufacturers. The control of the tolerances of these collets is often 10 times the specified value. 

F: What makes the ER16 system different from the standard? A: The standard collet system was developed significantly by Kress in the 80's is still used by many competitors today. The main difference is the runout repeatability. this is 3x better with the ER16 system than the standard system.

.

F What does runout repeatability mean? A: The difference in runout tolerance from clamping one tool to the next.
