Parlec C40-32ERP612 ER32 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-32ERP612 is an ER32 collet chuck with a CAT40 taper shank, designed for precision toolholding on CNC machining centers. It accepts ER32 collets with a clamping range of 2 mm to 20 mm (0.0787 to 0.7874 inches) and delivers a maximum TIR of 0.0002 inches for consistent, repeatable accuracy. The 6.12-inch projection provides clearance for deep-reach applications while the through-coolant design channels fluid directly to the cutting zone. This chuck is installed and serviced by CNC machinists and toolroom technicians in production and job-shop environments.

This collet chuck is suited for vertical and horizontal CNC machining centers equipped with CAT40 spindles. The ER32 collet series accommodates a wide range of tooling diameters, making it a versatile choice for milling, drilling, reaming, and tapping operations. The extended 6.12-inch projection makes it practical for workholding setups where clearance over fixtures or deep-pocket features is required. Balanced to 25,000 RPM, it is appropriate for high-speed machining applications where runout and vibration control are critical.

Key Features

• ER32 collet system accepts tooling from 2 mm to 20 mm (0.0787 to 0.7874 inches)
• CAT40 taper shank for direct mounting to CAT40 spindle interfaces
• 0.0002-inch TIR for high-precision toolholding and consistent part tolerances
• Through-coolant design delivers fluid directly through the spindle to the cutting tool
• 6.12-inch projection supports deep-reach and fixture-clearance applications
• Balanced to 25,000 RPM for compatibility with high-speed spindle applications

Compatibility

Designed for use with CAT40 spindle interfaces on CNC vertical and horizontal machining centers that support ER32 collets and through-spindle coolant delivery.

Installation Notes

Installation requires the machine spindle to be fully stopped and the tool carousel or spindle locked before mounting or removing the chuck. Use the specified ER32 collet nut wrench and a proper torque procedure per the machine tool manufacturer guidelines - do not over-torque or impact the collet nut. Verify through-coolant fittings and spindle coolant passages are clear and sealed before resuming coolant-assisted cuts. Inspect TIR with a dial indicator after mounting to confirm runout is within specification.
