Parlec C40BC-16EROS400 Er Collet Chuck CAT40 Taper

Product Description

The PARLEC C40BC-16EROS400 is a CAT40 taper shank ER collet chuck designed for precision milling and drilling applications on CNC machining centers. It accepts ER16-series collets with a clamping range of 0.5 mm to 10 mm (0.040 inches to 0.406 inches), making it suitable for small-diameter end mills, drills, and reamers. The chuck features a 4-inch projection from the gauge line and is balanced to 25,000 RPM, supporting high-speed spindle applications where runout and vibration control are critical. Through-coolant capability directs cutting fluid directly to the tool tip for improved chip evacuation and tool life. Installation and setup are handled by CNC machinists and tooling technicians.

This collet chuck is used in CNC vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The 4-inch projection suits applications requiring tool clearance in deep pockets or workholding situations where a longer reach is necessary. The EROS16 collet series provides consistent clamping force across the full capacity range, making this chuck appropriate for both roughing and finishing operations in production environments. Coolant is delivered through the spindle and DIN flange interface, compatible with through-spindle coolant systems on standard machining centers.

Key Features

• CAT40 taper shank for direct mounting in CAT40 spindle interfaces
• ER16 collet series with 0.5 mm to 10 mm clamping capacity
• 4-inch projection from gauge line for extended reach applications
• Balanced to 25,000 RPM for high-speed machining compatibility
• Through-coolant delivery via through-spindle and DIN flange interface
• Nut tightening torque of 52 ft/lb for consistent collet clamping

Compatibility

Designed for use in CAT40 spindle machining centers. Accepts ER16-series collets (EROS16 series). Through-coolant function requires a through-spindle coolant system or DIN flange coolant supply on the host machine.

Installation Notes

Installation is performed by a CNC machinist or tooling technician. Power down and lock out the machining center spindle before mounting or removing the chuck. Torque the collet nut to 52 ft/lb using the appropriate ER16 spanner wrench to ensure proper collet seating and clamping force. Verify coolant port alignment with the spindle coolant supply before initiating through-coolant operation, and confirm the collet size is within the 0.5 mm to 10 mm capacity range before clamping any tool.
