Mazak will feature its new QUICK TURN UNIVERSAL (QTU) 250MSY and INTEGREX i-100ST machine tools that are designed to process small parts in single set-ups.
Featuring a small footprint, the QUICK TURN UNIVERSAL series features technologies that, according to the company, 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 multitasking 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 integral spindle/motor headstock and 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," said a company spokesperson. "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°.
"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."
For PMTS attendees looking for a higher level of multitasking capability, Mazak offers the INTEGREX i-100ST. The machine employs two turning spindles, a milling spindle and a lower turret. Such features make it possible for shops to accomplish first and second machining operations simultaneously or perform required sequential operations on a single workpiece.
"Able to handle all processes from raw material input through the final machining, the INTEGREX i-100ST provides significant reductions in lead times and improves workpiece accuracy through the elimination of multiple set-ups," said the spokesperson. "Plus, its full 5-axis capability makes it easy to process fully prismatic parts from solid block or castings, round parts or highly contoured sculptured parts as chucked or bar fed work."
The turning spindles on the INTEGREX i-100ST share high performance capabilities, according to Mazak, because they both employ a 15 HP integral motor spindle with maximum spindle speeds of 6,000 RPM. Each spindle features a 6" chuck with a 2.4" bore size that can accommodate bar stock of up to 2" in diameter.
The machine's 10 HP, 12,000 RPM milling spindle mounts in the rotating B-axis and has a range of 240° in 0.0001° indexing increments. For high accuracy of motion, B-axis scale feedback comes standard on the machine. The machine's 36-tool magazine accommodates tools up to 5.1" in diameter when neighboring stations are empty and up to 3.5" in diameter when stations are occupied.
The lower drum turret on the INTEGREX i-100ST holds nine tools and can work at either the main or second spindle with the same tool, allowing the turret to perform balanced cutting operations on one part working in tandem with the machine's vertical milling spindle. It is also possible to perform milling operations with the lower turret.
Both the QTU 250MSY and INTEGREX i-100ST are designed to easily integrate with various forms of automation, including bar feeders, gantry loaders and robots. At PMTS, Mazak will pair these machines with bar feeders to showcase how basic automation can offer immediate increases in productivity and material utilization.
