Iscar's Hydrofit chucks are said to be suitable for stationary- or rotating-tool applications ranging to 15,000 rpm. The company says that the chucks are suitable for protecting brittle solid carbide tools in HSM work. Runout accuracy is 0.003 mm.
The chucks require only moderate hand torque on an Allen key to clamp and unclamp the tool—right in the spindle. The turn of an internal preset screw adjusts the datum to where the customer requires it. Optional threaded holes facilitate fine balancing. The chuck styles are available in HSK, DIN and SC machine interfaces and can accommodate four main shank types: taper shanks for rotating applications; VDI DIN 6980 shanks in sizes 30 and 40; ST 25, 32 Finefit ADJ with 070 flange for stationary tools; and Finefit ADJ tapers shanks with 070 flanges for rotating tools.
