Parlec C40-10SA4 Milling Machine Arbor CAT40 1 Inch

Product Description

The PARLEC C40-10SA4 is a stub-style milling machine arbor with a CAT40 taper shank, designed for use on CNC machining centers and manual knee mills equipped with CAT40 spindles. The arbor accepts a 1-inch bore cutter and delivers a projection of 4 inches from the spindle face, keeping the cutting tool close to the spindle for improved rigidity and reduced deflection. Overall length is 6.25 inches. The kit ships complete with three spacers and an arbor nut, giving the machinist immediate setup capability without sourcing additional hardware. This type of toolholder is installed and removed by licensed machinists and CNC setup technicians in production and job-shop environments.

The C40-10SA4 is suited for face milling, shell milling, and side milling operations where a 1-inch bore shell mill or face mill is required. The stub-style design is preferred when workpiece geometry or machine envelope calls for minimum gage length and maximum stiffness. It is appropriate for light to medium material removal rates in ferrous and non-ferrous machining applications.

Key Features

• CAT40 taper shank for direct spindle mounting on CAT40-equipped machining centers
• 1-inch arbor bore diameter accommodates standard 1-inch bore shell mills and face mills
• Stub style with 4-inch projection minimizes overhang and improves cutter rigidity
• 6.25-inch overall length suits typical CAT40 machining center gage-line clearances
• Includes three spacers and an arbor nut for complete, ready-to-use assembly
• Shoulder-to-nut length of 2.62 inches supports accurate cutter positioning along the arbor

Compatibility

Designed for use with CAT40 spindle-equipped CNC machining centers and milling machines accepting 1-inch bore shell mill or face mill cutters.

Installation Notes

Installation and removal of milling arbors should be performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before mounting or dismounting the toolholder. Use a properly calibrated torque wrench and the correct arbor nut spanner when securing the cutter and nut assembly. Inspect the CAT40 taper shank and spindle bore for nicks, chips, or contamination before seating the arbor, as surface defects will affect runout and tool life.
