Parlec C40-32ERF300 ER32 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-32ERF300 is an ER32 collet chuck designed for CAT40 taper spindles in CNC machining centers. It accepts ER32 collets with a capacity range of 2 mm (0.0787 inches) to 20 mm (0.7874 inches), covering a broad selection of cutting tool shank diameters. The chuck features a 3-inch projection and a total indicator runout (TIR) of 0.0002 inches, supporting accurate, repeatable tool positioning. Through-spindle coolant delivery is built in, directing coolant directly to the cutting zone. This tool holder is installed and serviced by CNC machine operators, setup technicians, and tool crib personnel in production machining environments.

The C40-32ERF300 is suited for use in vertical and horizontal machining centers equipped with CAT40 spindles. Its ER32 collet system accommodates a wide range of end mills, drills, reamers, and taps within the stated capacity range. The 3-inch projection makes it appropriate for general-purpose applications where moderate reach is needed without sacrificing rigidity. The through-coolant design supports higher cutting speeds and longer tool life in ferrous and non-ferrous machining operations. The chuck is balanced to 25,000 RPM, making it compatible with high-speed spindle applications.

Key Features

• CAT40 taper shank for direct mount to standard CAT40 spindles
• 0.0002-inch TIR for precise, repeatable tool runout control
• Through-spindle coolant delivery directs fluid to the cutting zone
• Balanced to 25,000 RPM for high-speed machining compatibility
• 3-inch projection with 5.69-inch overall length for general-purpose reach

Compatibility

Designed for use with CAT40 taper spindles and standard ER32 collets. Compatible with machining centers that support through-spindle coolant delivery.

Installation Notes

Installation should be performed with the machine spindle fully stopped and the control in an estop or locked-out state per facility lockout/tagout procedures. Use the specified ER32 collet nut wrench and a torque wrench appropriate for the collet nut size to achieve proper clamping force. Inspect the taper and spindle bore for chips or contamination before seating the chuck. Verify coolant port alignment with the spindle coolant supply before returning the machine to service.
