Schunk 1000067 Hydraulic Tool Chuck CAT40 19mm

Product Description

The SCHUNK 1000067 is a hydraulic tool chuck designed for precision metal-cutting applications on CAT40 taper-shank spindles. It uses hydraulic clamping force to grip cutting tools with minimal runout, achieving a TIR of 0.003 mm for consistent accuracy in finishing and semi-finishing operations. The chuck accepts tools with a 19 mm bore diameter and provides 101.6 mm of projection from the spindle face, making it well suited for deep-reach machining setups. Through-coolant capability directs cutting fluid directly to the tool tip. Licensed machinists and CNC tooling technicians are the primary users of this chuck.

This hydraulic chuck is intended for use on CNC machining centers equipped with CAT40 spindle interfaces. With a 51 mm clamping depth and a 34 mm nose diameter, it accommodates solid carbide end mills, drills, and reamers in the 19 mm shank size range. The 25,000 RPM balance rating makes it appropriate for high-speed machining applications in aerospace, die-mold, and general precision manufacturing environments. Its hydraulic expansion mechanism reduces chatter and extends tool life compared to mechanical set-screw holders.

Key Features

• CAT40 taper shank for direct mount on compatible CNC machining center spindles
• 19 mm bore diameter with 51 mm clamping depth for secure tool retention
• TIR of 0.003 mm for high-precision, low-runout tool holding
• Balanced to 25,000 RPM for high-speed machining operations
• Through-coolant design routes fluid directly to the cutting zone
• 101.6 mm projection supports deep-reach and extended-reach tooling setups

Compatibility

Designed for use with CAT40 taper spindle interfaces on CNC vertical and horizontal machining centers accepting 19 mm shank tooling.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist. Always power down and lock out the machine spindle before mounting or removing the chuck. Use the correct CAT40 retention knob and torque it with a calibrated torque wrench per the machine tool builder specifications. Inspect the taper bore and spindle taper for contamination or damage before seating the chuck, as any debris will directly affect runout and balance.
