Schunk 1447937 Hydraulic Tool Chuck CAT50 3/4 in

Product Description

The SCHUNK 1447937 is a hydraulic tool chuck designed for high-precision CNC machining applications. It uses a CAT50 taper shank interface and accepts tooling with a 3/4-inch (19.05 mm) bore diameter. Hydraulic clamping technology delivers consistent gripping force and excellent vibration damping, making it well suited for finishing operations and high-speed cutting where runout control is critical. The chuck is balanced to 25,000 RPM and features a total indicator runout (TIR) of 0.003 mm, supporting tight-tolerance work. Through-coolant capability directs cutting fluid directly to the tool tip for effective chip evacuation and heat management.

This chuck is intended for use on CAT50-spindle machining centers in production and job-shop environments. It is a direct-mount toolholder requiring no additional adapters when paired with a compatible CAT50 spindle. The 81 mm projection and 41.5 mm clamping depth accommodate a wide range of end mills, drills, and reamers in standard 3/4-inch shank diameter. Machinists, tooling engineers, and CNC setup technicians are the primary users in both vertical and horizontal machining center configurations.

Key Features

• CAT50 taper shank for direct mounting on CAT50-spindle machining centers
• Hydraulic clamping mechanism provides consistent grip force and vibration damping
• Balanced to 25,000 RPM for high-speed machining applications
• TIR of 0.003 mm supports tight-tolerance and finishing operations
• Through-coolant design routes fluid directly to the cutting zone
• 41.5 mm clamping depth and 81 mm projection for flexible tooling reach

Compatibility

Designed for use with CAT50-spindle CNC machining centers accepting standard CAT50 taper toolholders and 3/4-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle drive before mounting or removing the toolholder. Use a calibrated torque wrench and follow the machine tool manufacturer's draw bar torque specification when securing the chuck in the spindle. Inspect the taper bore and shank for contamination or damage before seating the holder.
