The QTU 250MSY small footprint multi-tasking turning center from Mazak is ideal for machining high precision small parts used in medical devices, engine components and electronic enclosures.

Posted: August 25, 2015

The QTU 250MSY from Mazak features a milling turret with a rotary tool spindle to perform Multi- Tasking operations, a second turning spindle for Done In One® part production, Y-axis functionality for off-centerline machining, an advanced integral spindle/motor headstock, special servo-driven turret, spindle/motor headstock for extreme rigidity in heavy-duty machining as well as high-speed, high-torque operations with zero backlash. A full-circumference C-axis headstock break provides high-accuracy positioning to within 0.0001 deg.

Mazak Corporation (Florence, KY) showcases the high levels of accuracy and productivity that shops can achieve with the advanced Multi-Tasking technology it features in its new Quick Turn Universal (QTU) 250MSY small footprint turning center for processing small parts in single setups. With the QTU 250MSY, shops never have to choose between quality and affordability. While simple in their design, these machines feature innovative technologies that bring precision and value to the production of parts such as medical devices, engine components and electronic enclosures.

The QTU 250MSY features a milling turret with a rotary tool spindle to perform Multi-Tasking operations, a second turning spindle for Done In One® part production and Y-axis
functionality for off-centerline machining. Other key machine features include an
advanced integral spindle/motor headstock and special servo-driven turret design.

The machine’s spindle/motor headstock offers extreme rigidity in heavy-duty machining
as well as high-speed, high-torque operations. Its power comes from a variable-speed
AC inverter that eliminates the need for any belts or pulleys, resulting in zero backlash.
A full-circumference C-axis headstock break design provides high-accuracy positioning
to within 0.0001 deg.

Offering multiple tool configurations, the servo-driven turret on the QTU 250MSY uses a
roller gear cam drive system to achieve a smooth high-speed, high-accuracy indexing
motion as well as eliminate the need for expensive curvic/index couplings. Without
these couplings, it is possible to increase the turret’s capacity to include up to 25 small
tools as well as program an infinite number of index positions without having to make
any changes to the turret housing.

The QTU 250MSY can easily integrate with various forms of automation, including bar feeders, gantry loaders and robots to showcase how basic automation can offer
immediate increases in productivity and material utilization.
