TOOLING SYSTEMS INTRODUCTION
Hydraulic Chucks Clamping Clamping
Screw Sleeve
ISCAR has expanded its toolholder clamping options
by adding hydraulic chucks. These hydraulic chucks Actuator
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
Hydraulic
Oil
Axial Adjustment

• High runout accuracy of less than 0.003 mm Operating Instructions
• Very low torque required to activate the clamping
To ensure correct functioning of the hydraulic chuck,
mechanism, by using a 4 mm Allen key the following instructions should be followed:
• Prolongs cutting tool life and improves Tools with cylindrical shanks and shanks Type AB with
one Weldon flat (DIN 1835 part 1 and DIN 6535 HB)
surface finish due to vibration damping should have h6 tolerance. Tools with accordance to DIN
• Easy presetting by using an internal preset screw 6535 HE (whistle notch) and Type B with two Weldon
• All rotating chucks feature a symmetrical and balanced flats (DIN 1835 part 1) should be used in reduction
sleeves, to avoid damaging the chucking bore.
design for high speed machining of up to 25, 000 min-1
• Consistent and secure clamping force when • The tool shank must be burr-free and free of dirt.
Insert the tool shank up to the stopper. Make sure that
used within the recommended speed range the minimum chucking length (L min) is maintained.
• Suitable for both Weldon and cylindrical shank clamping If the minimum clamping depth is not met, there will be
• Very convenient and safe tool change on the machine a loss of accuracy, the maximum admissible torque will
be reduced, and the tool holder might get damaged.
Two main HYDROFIT chuck types are available
• The clamping screw must be turned in manually
• Taper shanks for rotating applications with an Allen key to the limit stop. DO NOT APPLY
• VDI DIN 69880 in sizes 30 and 40 for EXCESSIVE FORCE. Tightening torque: Max.10Nm
stationary applications on CNC lathes Never actuate the actuation screw with a
power screwdriver! Do not attempt to clamp
the chuck without a shank inside as this will
damage the expansion clamping sleeve.
• Do not combine several extensions
• To release the tool, turn the clamping screw in a
counter-clockwise direction until tool can be removed.
The clamping screw is not secured against
dropping out! The vent screw of the hydraulic
system is protected with a resin. Don’t remove it!
