expansion chucks always offer a T.I.R accuracy of less than 3 microns. The series with
HSK-mounting includes HSK A-50, A-63 and A-100 with all the popular clamping diameters.
Manually operated HSK mountings are available in the following sizes: C-40, C-50 and C-63. A new and more accurate ABS-H interface is offered as well. Further sizes, as well as mountings which are similar to the standard versions, are offered upon special request.
In the field of steep tapers, basically 3 different chuck versions for various machining tasks are offered. Different lengths and outside contours of the expansion chucks offer solutions for tool- adapted clamping tasks, where all the popular clamping diameters are covered.
The success of this precision toolholder is based on the systems advantages, such as a high permanent T.I.R. accuracy and a high repeatability, a good dampening of vibration and easy handling. All TENDO-Expansion Chucks are pre-balanced and therefore suitable for high r.p.m's. When the chuck is additionally fine balanced, speeds of 20,000 - 40,000 r.p.m. are possible.
