Overview
The Mazak QUICK TURN SMART 350 is a mid-range CNC turning center from Mazak's SMART series, positioned to deliver production turning capability with an emphasis on ease of use, setup speed, and intelligent automation features. The SMART designation indicates an emphasis on guided operation, simplified programming, and integrated measurement features that reduce the skill barrier for turning complex parts.
The QUICK TURN SMART 350 features a 65 mm (2.56 in) bar capacity with a 10-inch chuck on an A2-6 spindle, maximum swing of 420 mm (16.5 in), and machining length of 1,020 mm (40.2 in). The main spindle delivers 22 kW (30 hp) at up to 4,000 RPM, suited for production turning in steel, stainless, and aluminum. The 10-station turret accommodates a full complement of OD, ID, and face tooling for complex turned part geometries.
The SMART series control architecture builds on MAZATROL SmoothAi with additional intelligent features including Intelligent Thermal Shield for automatic compensation, voice guidance for setup procedures, and integrated part measurement cycles that enable closed-loop dimensional control without separate CMM measurement between parts. These features aim to make the machine accessible to less experienced operators while maintaining the precision expected of Mazak equipment.
Pricing for the QUICK TURN SMART 350 runs $130,000 to $175,000 for standard configurations. The machine competes with the Haas ST-30, the DMG Mori CLX 450, and the Doosan Puma 3100 in the mid-size production turning segment.

Strengths & Limitations
Strengths
- SMART series intelligent features including voice guidance and integrated measurement cycles reduce operator skill requirements and setup time compared to standard turning centers
- 22 kW spindle provides production-level turning power for a wide range of materials including stainless steel and alloy steel at medium diameters
- 1,020 mm machining length handles shaft-type parts common in general industrial, automotive, and pump manufacturing
- MAZATROL SmoothAi conversational programming with thermal compensation enables efficient part production with minimal programming expertise
Limitations
- 4,000 RPM spindle speed is lower than many competitors at this price point, potentially limiting small-diameter finishing speed and aluminum machining performance
- 10-station turret limits tooling capacity for complex parts requiring many different tool profiles
- SMART series features add cost premium over standard QUICK TURN models; shops with experienced programmers may not benefit from the guided features that justify the price

Frequently Asked Questions
01
SMART on Mazak turning centers indicates the machine includes Mazak's intelligent operation features: SmoothAi control with AI thermal compensation, voice guidance for setup and programming, integrated in-process measurement cycles for automatic dimensional control, and enhanced monitoring for tool wear and machine health. These features are designed to improve productivity and reduce errors for both experienced and less experienced operators.
02
The standard QUICK TURN SMART 350 uses a static tooling turret. A variant with driven tooling (M suffix) and optionally Y-axis (MY suffix) is available for shops needing off-center milling and drilling capability. If your parts are purely turned with no off-center features, the standard 350 is the appropriate and more economical choice.
03
The QT SMART 350 supports in-process gauging via a touch probe mounted in the turret. After turning a diameter or facing an end, the control automatically measures the actual dimension, compares it to the programmed target, and updates the tool offset to compensate for wear or thermal drift. This closed-loop measurement approach reduces scrap from dimensional drift in long production runs and can eliminate the need for manual gauging between parts.
04
The QUICK TURN SMART 350 adds the SmoothAi control with AI thermal compensation, voice guidance, and in-process gauging support over the standard QUICK TURN 350. The physical platform, axis travels, and spindle specifications are similar. The SMART version costs more but delivers better sustained accuracy and lower operator skill requirements. For shops running unattended or lights-out production, the SMART series features pay back quickly in reduced scrap and rework.
05
Mazak specifies the QUICK TURN SMART 350 at positioning accuracy of 0.002 mm and repeatability of 0.001 mm for linear axes under stable thermal conditions. The SmoothAi Intelligent Thermal Shield compensation maintains similar performance across production shifts by continuously modeling and correcting for thermal growth in the spindle and ballscrews. In practice, dimensional repeatability of 0.005 mm or better is achievable for steel turning in a temperature-stable shop environment.
