Murata Machinery Co., Ltd. developed the spindle active lathe "MV200"

Murata Machinery has introduced the spindle active lathe model "MV200," which will be showcased at the "MECHATRONICS TECHNOLOGY JAPAN" exhibition, held from October 17 to 20, 2007, at the Nagoya International Exhibition Center. The machine will be available for viewing and demonstration on the same day. With a chuck diameter of 250 mm, the MV200 is designed to offer enhanced efficiency compared to its predecessor, the MV120, which features a 205 mm chuck. What sets the MV200 apart is its unique manual operation with an automated workpiece loading system. Unlike traditional manual lathes, this model allows the workpiece to be automatically clamped onto the spindle chuck, eliminating the need for time-consuming tasks like manually mounting blanks. This feature significantly reduces the potential for human error and shortens the time required for setup and removal. The lathe is capable of automatically loading the next workpiece while the operator is engaged in machining. As a result, the entire process—from loading to unloading—can be completed in just 3.0 seconds, according to company measurements. By automating the loading process, the machine increases the number of units each operator can manage, improving overall productivity and reducing labor costs. When multiple MV200 units are arranged in a production line, it becomes easier to adapt to changes in the manufacturing process, as workpieces are handled manually between operations. This flexibility makes the system ideal for small-batch or custom production runs, where product variations are common. In terms of performance, the X-axis and Z-axis of the MV200 can move at speeds of up to 40 m/min and 30 m/min, respectively. It is capable of machining a workpiece with a diameter of 200 mm and a length of 100 mm under standard conditions. The machine also comes equipped with a 10-point servo head and an auxiliary thread comb cutter table. Additional tooling options, such as a rotary cutter assembly, deburring unit, and grinding attachment, can be mounted on the tool table, enabling centralized processing and streamlining the workflow.
