Parlec C40-10SA400 Milling Machine Arbor CAT40 1 Inch

Product Description

The PARLEC C40-10SA400 is a stub-style milling machine arbor designed for use with CAT40 taper spindles in vertical and horizontal milling applications. The arbor accepts 1-inch bore shell mills and face mills, transmitting torque from the spindle to the cutter with a rigid, short-projection setup that minimizes deflection during heavy cuts. With an overall length of 6.69 inches and a 4-inch projection, this arbor suits production environments where rigidity and repeatability are priorities. It ships complete with three spacers, a drive key, and a lock screw, so the unit is ready for immediate installation without sourcing additional hardware.

This arbor is suited for CNC machining centers equipped with CAT40 taper toolholders. The stub configuration is preferred when machining conditions demand maximum rigidity and reduced overhang, such as face milling, shoulder milling, and light profiling operations. It is a common toolholder choice in job shops and production floors running steel, aluminum, and cast-iron workpieces where chatter control and tool runout are critical factors. A licensed machinist or CNC setup technician is the typical end user for this component.

Key Features

• Stub-style design reduces overhang and improves rigidity during milling operations
• CAT40 taper shank provides positive drive engagement with standard CAT40 spindles
• 1-inch arbor diameter accommodates standard shell mill and face mill bores
• 4-inch projection supports a range of cutter widths and spacer configurations
• Includes three spacers, one drive key, and one lock screw for complete out-of-box installation
• Shoulder-to-nut length of 3.25 inches allows flexible axial positioning of the cutter

Compatibility

Designed for use with CAT40 taper spindle machining centers accepting 1-inch bore shell mills and face mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the arbor. Ensure the taper shank and spindle taper are clean and free of chips, oil, or burrs before seating the arbor to maintain accurate runout. Torque the retention knob or drawbar according to the machine tool manufacturer specifications, not arbor specifications.
