The TV Series drill/tap machines are built around a 24,000-rpm high-speed spindle. MC Machinery Systems Inc. is expanding its product line with a new series of CNC milling machines. MC Machinery is a business unit of Mitsubishi Heavy Industries, and offers machines for milling, EDM, and laser and waterjet cutting, as well as press brake machines. The new Diamond Cut line of general-purpose milling machines includes five different styles of vertical machining centers and drilling and tapping machines. MC Machinery said the new offerings reaffirm its focus on improving its products for the U.S. manufacturing sector.
The MCV Series vertical milling machine has two spindle/tooling system types. Its CAT-40 tooling system uses an 8,000-rpm motor, and the CAT-50 tooling uses a 6,000-rpm motor. Reportedly, it performs well at producing fixtures, mold bases, and secondary machining. The series is supplied with “coolant-through-spindle” preparation and an M70 Mitsubishi controller.
MCV machines can be equipped with a ZF gearbox for torque levels four times higher than a standard motor.
The DV Series is another general-purpose machine, with a 15,000-rpm direct-drive spindle and CAT-40 tooling. It will accommodate smaller cutting tools, for more intricate milling work, and is recommended for job shops because of the range applications it suits. The series is supplied with coolant-through-spindle preparation and an M70 Mitsubishi controller.
The DM Series is designed with a 20,000-rpm HSK-A63 spindle, with a more rigid and accurate tooling system. This series is recommended for close-tolerance work, notably for applications in mold and die production. The 32-position automatic tool changer offers better tool life management and increases machine productivity. Standard features include a M720 Mitsubishi controller, linear scales, and roller guideways.
The SV Series is built with a heavy-duty box way construction for its X, Y, and Z axes, giving it the rigidity and stability needed to machine large parts. It is particularly well suited for maximum material removal thanks to its ability to handle larger tools. It is designed with a 10,000-rpm spindle, CAT-50 tooling, and hand-scraped box way guides. The series is supplied with coolant-through-spindle preparation, an M70 Mitsubishi controller, and optional ZF gearbox for higher torque.
Finally, the TV Series drill/tap machines are built around a 24,000-rpm high-speed spindle driven by a 5HP motor. The BBT-30 dual contact tooling provides rigidity and better Z depth control during operation, according to the developer. “Two second” tool changes make it possible to achieve multi-axis machining with one setup, according to the developer. A bi-directional tool magazine is driven through advanced PLC software, operated via the M70 Mitsubishi controller. A CAM-driven tool magazine allows rotation and accuracy, and smooth motion even when large tools are loading.
