The QT is Mazak's Quick Turn CNC lathe, the workhorse turning center line spanning chuck sizes from small precision work to heavy chucking. A built-in motor spindle eliminates belt vibration, and the MAZATROL SmoothG control runs both conversational and G-code programming.

Why a built-in motor spindle for production turning?

A belt-drive spindle introduces vibration and loses the wide constant-power range that a production run depends on. The QT's built-in spindle keeps the 340 mm cut smooth across its speed range, so the same setup roughs and finishes a part without chatter — the reliability a mass-production floor counts on shift after shift.

• 340 mm cutting diameter, up to 1,082 mm length
• Built-in spindle up to 6,000 rpm, 11/15 kW
• 12-station turret, 52/65 mm bar
• MAZATROL SmoothG control

Against a belt-drive lathe, the QT trades the belt for a built-in spindle — the smoothness and constant power that keep a production part in tolerance.
