Sandvik Coromant 5764273 Modular Turning Head Size 40

Product Description

The SANDVIK COROMANT 5764273 is a modular turning profiling head designed for internal turning operations on CNC lathes and turning centers. Part of the T-Max P series, this head features a size 40 system with a head length projection of 38 mm (1.496 inches) and a neck diameter of 40 mm (1.575 inches). It accepts CNMG 120408 inserts secured by a wedge clamping method, delivering reliable insert location and consistent cutting performance. The right-hand cutting direction and integrated through-coolant capability make it well suited for deep-bore profiling work where chip evacuation and heat management are critical. Licensed machinists and CNC operators install and service this component.

This profiling head is intended for internal turning and profiling applications where access to the bore requires a compact, rigid head connection. The size 40 system with a head connection size of 20 supports use in modular boring bar assemblies configured for bores with a minimum hole diameter of 50 mm (1.969 inches) and a maximum hole depth of 38 mm (1.496 inches). The center-to-cutting-edge distance of 27 mm (1.063 inches) allows precise positioning of the insert tip relative to the bore centerline. Through-coolant delivery directs fluid directly to the cutting zone, supporting extended insert life and cleaner chip flow in ferrous and non-ferrous materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the control is in a safe state before mounting or demounting the profiling head. Follow the modular coupling torque and seating procedures specified in the T-Max P system tooling manual for the head connection size in use. Verify coolant line integrity and flow before resuming cutting operations.
