INTRODUCTION Hydraulic Chucks ISCAR-ETM has expanded its toolholder clamping options by adding hydraulic chucks. These hydraulic chucks range from 6-32 mm. This type of chucking system is used for Clamping Clamping Screw Sleeve rotating and stationary applications. Actuator Main Applications • Fine and accurate machining • Reaming • Drilling TOOLING SYSTEMS • Finish milling • Internal turning Hydraulic Oil Axial Adjustment Screw 0.003 Features • High runout accuracy of less than 0.003 mm • Very low torque required to activate the clamping d mechanism, by using a 4 mm Allen key • Prolongs cutting tool life and improves surface finish due to vibration damping 2.5xd • Easy presetting by using an internal preset screw • All rotating chucks feature a symmetrical and balanced design for high speed machining of up to 25,000 min-1 • Available with threaded holes for fine balancing • Consistent and secure clamping force when used within the recommended speed range • Suitable for both Weldon and cylindrical Operating Instructions shank clamping • Very convenient and safe tool change on To ensure correct functioning of the the machine hydraulic chuck, the following instructions should be followed: Tools with cylindrical shanks in accordance with DIN 1835 Two main HYDROFIT chuck types and DIN 6535 forms (HA) and B (HB) up to are available 20 mm diameters should be manufactured according • Taper shanks for rotating applications to h6 tolerance and Ramin = 0.3 ground. • VDI DIN 69880 in sizes 30 and 40 for Tools with DIN 6535 HE (whistle notch) shanks stationary applications on CNC lathes should be used in reduction elements, to avoid damaging the chucking hole. • Clean any grease and dirt from the chuck mounting hole and the tool shank. Insert the tool shank up to the stopper. Make sure that the minimum chucking length is maintained. • Using the hexagonal-headed key, rotate the clamping screw in a clockwise direction until the end. Do not attempt to clamp the chuck without a shank inside as it may break the expansion clamping sleeve. • To release the tool, turn the clamping screw in a counterclockwise direction by about 5 or 6 revolutions and remove the tool. 846 846 ISCAR ISCAR
