HIGH-PRODUCTIVITY TURNING CENTER FOR JOB SHOPS

With the QUICK TURN SMART 200M, Mazak (Florence, KY) brings the QTSMART series of machines into its family of multi-tasking technology by adding rotary tool capabilities. The QTSMART 200M also evolves the series from 2-axis lathes to 3-axis lathes, increasing productivity by reducing the number of setups required. The QTSMART series delivers fast axis feed rates and the user-friendly SMART control, making it ideal for job shops and other high production environments.

The QTSMART 200M headstock features an 8 in chuck, mounted on a 25 hp, 5,000 rpm integrated spindle motor with a 2.56 in spindle bore that is optimized for machining performance. The machine utilizes a 12-position drum turret and 7.5 hp, 4,500 rpm rotary tool spindle for milling, drilling, and tapping operations, allowing many processes to be completed in a single machine cycle.

The turning center utilizes the new MX Hybrid Roller Guide System on the X- and Z-axes to ensure high rigidity and smooth cutting. The QTSMART 200M also features X-axis ball screw pretension for high accuracy. Additionally, the machine is very reliable, particularly when set up for long runs with an automatic bar-feeder system. The MX Hybrid Roller Guide System is integrated into the QTSMART 200M to deliver levels of durability and reliability that result in long-term accuracy. The MX Hybrid Roller Guide System increases vibration dampening to extend tool life, handles higher load capacities, accelerates and decelerates quicker to shorten cycle times, consumes less oil for "greener" operations, and lasts longer with less required maintenance.

The recently developed SMART control simplifies turning operations on the QUICK TURN SMART series. SMART is designed for ease of operation and offers a 10.4-in LCD color display and the familiar QWERTY keyboard. A pointing device, acting like a mouse, is also at the operator's fingertips. Conversational part programming can also be accomplished. SMART control also accepts EIA/ISO programs.

The machine also features an NC servo-driven tailstock to enable automated processes. The tailstock is fully programmable, driving the W-axis on its own AC servomotor and ball screw. 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.
