Sharp Industries’ M series of large-swing, big-bore manual lathes is suitable for large oil pipe work, heavy shaft turning jobs and large-diameter steel rods. The series includes lathes with swings of 40", 50", 60", 70" and 80"; distance between centers ranging from 60" to 315"; and spindle bores sizes of 6", 9" and 12"

The Sharp M-series machine base is a one-piece structure made from high-grade Meehanite casting to maintain durability and stability under heavy cutting conditions. The 32"-wide bedways are induction-hardened and ground with separate bedways at the front of the bed to support the heavy carriage and apron. According to the company the bedways promote better dispersion of cutting force from the carriage. The apron is equipped with a six-way control of the carriage and cross-slide movements. The cross-slideways are coated with Turcite-B for improved oil retention and wear resistance.

The headstock is designed with three-point bearing support of the spindle, and the large spindle motor enables power ranging to 50 hp. The spindle is made from forged chrome alloy material, while the gears and shafts are made from hardened and ground alloy steel. The rear chuck adapter enables double-chuck mounting, and the heavy-duty tailstock is available with motorized movement on the quill and the base for ease of operation, the company says.
