Value Collection BNC/EC/4 Live Center MT4 Taper Shank

Product Description

The VALUE COLLECTION BNC/EC/4 is a taper shank live center designed for use in lathe tailstocks and live center applications requiring a bull nose point configuration. Built from steel with an MT4 (Morse Taper 4) shank, this center supports workpieces up to 750 pounds and delivers a radial load capacity of 700 pounds. The bull nose point style accommodates hollow or short-bored workpieces where a standard point would not seat properly. With an overall length of 7.6 inches and a head diameter of 5.04 inches, the BNC/EC/4 is suited for medium to heavy-duty turning operations performed by machinists and toolroom operators.

This live center is appropriate for use in manual engine lathes and CNC lathes equipped with a Morse Taper 4 tailstock bore. The bull nose point, measuring 1.38 inches in diameter and 2.44 inches in length, supports workpieces that cannot accept a standard pointed center. Typical applications include shaft turning, bar stock support, and any operation requiring steady workpiece support at the tailstock end. The 75-degree included angle and 0.0004 inch accuracy rating make this center suitable for precision turning work in job shop, production, and maintenance environments.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the lathe before inserting or removing the live center from the tailstock. Clean the taper shank and tailstock bore thoroughly before seating to ensure accurate alignment. Do not use a hammer to drive the center into the bore; use the tailstock quill feed to seat it properly.
