TOOLING SYSTEMS INTRODUCTION HYDROFIT HOLDING LINE 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 rotating and stationary applications. Main Applications Fine and accurate machining Reaming Drilling Finish milling Internal turning Features High runout accuracy of less than 0.003 mm Very low torque required to activate the clamping mechanism, by using a 4 mm Allen key Prolongs cutting tool life and improves surface finish due to vibration damping 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 shank clamping Very convenient and safe tool change on the machine Two main HYDROFIT chuck types are available Taper shanks for rotating applications To ensure correct functioning of the hydraulic chuck, the following instructions should be followed: Tools with cylindrical shanks in accordance with DIN 1835 and DIN 6535 forms (HA) and B (HB) up to 20 mm diameters should be manufactured according to h6 tolerance and Ramin = 0.3 ground. Tools with DIN 6535 HE (whistle notch) shanks 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 ISCAR
