Parlec C50-32ERF400 ER32 Collet Chuck CAT50 Taper

Product Description

The PARLEC C50-32ERF400 is an ER32 collet chuck designed for CAT50 taper spindles on CNC machining centers. It provides a clamping range of 2 to 20 millimeters (0.0787 to 0.7874 inches) and delivers a maximum total indicator runout (TIR) of 0.0002 inches, making it well suited for precision milling, drilling, and reaming operations. The 4-inch projection positions the collet nose clear of workpiece fixtures without sacrificing rigidity. Through-spindle coolant capability routes coolant directly to the cutting zone, extending tool life and improving chip evacuation. Licensed machinists and CNC setup technicians install and operate this chuck in production and job-shop environments.

The C50-32ERF400 is used in horizontal and vertical machining centers equipped with CAT50 spindle interfaces. The ER32 collet series accommodates a wide range of round-shank tooling, supporting applications from light finishing passes to moderate stock-removal operations. At 8 inches overall length with a 4-inch projection, this chuck suits setups requiring reach beyond standard short-projection holders. Balanced to 20,000 RPM, it is appropriate for high-speed machining applications where spindle balance directly affects surface finish and bearing life.

Key Features

• ER32 collet system accepts 2 to 20 mm shank tooling in a single chuck body
• CAT50 taper shank for positive location in standard V-flange spindles
• 0.0002-inch TIR for precision toolholding in close-tolerance work
• Through-spindle coolant delivery routes coolant to the cutting edge
• Balanced to 20,000 RPM for high-speed machining compatibility
• Wrench-actuated collet nut for secure, repeatable tool clamping

Compatibility

Designed for use with CAT50 taper spindles and ER32 series collets. Accepts tooling with shank diameters from 2 to 20 mm.

Installation Notes

Installation requires the machine spindle to be fully stopped and the spindle brake engaged before mounting or removing the chuck. Use the appropriate CAT50 retention knob torqued per the machine tool builder specification and an ER collet wrench sized for the ER32 collet nut. Verify through-coolant port alignment with the spindle coolant supply before operation. Inspect the taper shank and spindle bore for contamination or damage before seating the chuck.
