Mazak’s Quick Turn (QT) Smart series of two-axis lathes are designed for high productivity turning. The line’s QT-SMART 350 delivers fast axis feed rates, high accuracy and rigidity and a user-friendly Mazatrol Smart control, making it especially useful for job shops and other high production environments.

The lathe headstock features a 12" chuck, mounted on a 40-hp, 3,300-rpm integrated spindle motor that is optimized for machining performance. It delivers maximum torque of 596 foot-pounds and allows a 4” bar material to be machined.

The turning center uses Roller LM guides on the X and Z axes to ensure high rigidity and smooth cutting at feed rates of 1,811 ipm on the X axis and 1,299 ipm on the Z axis. The machine also features X-axis ballscrew pretension for high accuracy, as well as a 12-position, high-speed, non-lift drum turret for rapid tool indexing.

The Mazatrol Smart control simplifies turning operations; it is designed for ease of operation and offers a 10.4" LCD color display and the Qwerty keyboard. A pointing device, acting like a mouse, and USB port for downloading programs, are also at the operator’s fingertips. Conversational part programming can be accomplished in Mazatrol language. The control also accepts EIA/ISO programs.

The lathe also features an NC servodriven tailstock to enable automated processes. The tailstock is fully programmable, driving the W axis on its own AC servomotor and ballscrew. Through the part program, the tailstock will retract to a known position, and its center makes contact with the part with consistent holding pressure. Further, because of its positive independent drive system, the tailstock can be used to drill holes on a shaft centerline adding versatility to the jobs it can process.
