Accupro 781023 Live Center MT4 Morse Taper Standard Point

Product Description

The ACCUPRO 781023 is a live center designed for lathe and turning operations, featuring a Morse Taper shank for secure, repeatable mounting in compatible tailstocks and machine spindles. Built around an MT4 taper size, this unit supports a maximum workpiece weight of 1,234.59 pounds and spins up to 4,500 RPM, making it suitable for moderate to heavy turning work. The standard point style and a 60-degree included angle suit general-purpose turning applications. Accuracy is held to 0.003 mm, giving machinists reliable concentricity during extended production runs. Licensed machinists and CNC lathe operators are the primary installers and users of this tooling.

This live center is appropriate for use in machine shops handling both production and jobbing work on manual or CNC lathes equipped with MT4 tailstock bores. The 78.00 mm head diameter and 111.50 mm point-to-gauge-line dimension allow clearance on medium to large workpieces. The standard point configuration handles shaft turning, facing, and general between-centers work across a broad range of materials. It is well matched to operations where workpiece weight and rotational speed fall within the rated limits of the unit.

• 16.00 mm point diameter and 77.20 mm point length provide adequate clearance on most workpiece bores

Compatibility

Designed as an OEM-style replacement or upgrade live center for lathes equipped with an MT4 Morse Taper tailstock bore.

Installation Notes

Installation and removal should be performed by a qualified machinist with the lathe powered down and brought to a complete stop. The Morse Taper shank must be clean and free of chips, burrs, or oil before seating to ensure full contact and prevent fretting. A drift and mallet are typically used for removal; never use impact tools on the rotating body. Confirm that workpiece weight and operating RPM remain within the rated limits before commencing a cut.
