Parlec C40-40ERF400 ER40 Collet Chuck CAT40 Taper

Product Description

The PARLEC C40-40ERF400 is an ER40 collet chuck with a CAT40 taper shank, designed for CNC machining centers that require precise, high-speed tool holding. It accepts ER40 collets with a capacity range of 3 mm (0.1181 inches) to 30 mm (1.1811 inches), covering a wide range of cutting tool shank diameters. The chuck features a 4-inch projection and delivers a TIR (total indicator runout) of 0.0002 inches, making it suitable for applications where concentricity and repeatability are critical. Through-spindle coolant capability is built in, directing coolant directly to the cutting edge for improved tool life and chip evacuation.

This collet chuck is intended for use in CAT40-spindle machining centers in production and job-shop environments. It is suited for milling, drilling, reaming, and tapping operations where through-coolant delivery and tight runout tolerances are required. The ER40 collet system is a widely adopted standard, and this chuck works with any compliant ER40 collet purchased separately. Licensed machinists, CNC operators, and tooling setup technicians are the typical end users for this type of toolholder.

Key Features

• ER40 collet system accepts tool shanks from 3 mm to 30 mm (0.1181 to 1.1811 inches)
• CAT40 taper shank for direct mounting in CAT40 machining center spindles
• TIR of 0.0002 inches for high concentricity and repeatability
• Through-spindle coolant delivery routes coolant to the cutting zone
• 4-inch projection provides clearance for a range of workpiece and fixture configurations
• Balanced to 25,000 RPM for high-speed machining applications

Compatibility

Designed for CAT40-spindle CNC machining centers. Accepts standard ER40 collets. Wrench-actuated collet nut with a 2.47-inch collet nut diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool change cycle is complete before handling the toolholder. Use the correct CAT40 retention knob torque specification supplied by the machine manufacturer. Confirm coolant port alignment with the spindle coolant supply before engaging through-coolant operation.
