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

Murata Machinery has introduced the spindle active lathe model "MV200," which is set to 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 size of 250 mm in diameter, the MV200 shares similarities with its predecessor, the MV120, which features a 205 mm chuck. However, what sets the MV200 apart is its manual design combined with an innovative feature: the workpiece is automatically loaded into the spindle chuck, eliminating the need for traditional loading tasks such as manually securing blanks onto the chuck. This automatic loading system significantly reduces operational errors and shortens the time required for assembly and disassembly. While the operator is engaged in machining, the lathe automatically loads the next workpiece, and the entire process—from loading to unloading—takes only 3.0 seconds, according to company measurements. By automating this crucial step, the efficiency of each operator increases, allowing them to manage more machines simultaneously. When multiple MV200 units are arranged in a production line, the system becomes more flexible, especially when it comes to process adjustments. Since workpieces are manually handled between operations, the setup can easily adapt to changes in production requirements. This makes the MV200 ideal for small-batch or single-piece production of customized parts, offering greater versatility compared to fully automated systems. In terms of performance, the X and Z axes of the MV200 offer rapid feed rates of 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 includes a 10-point servo head, along with an auxiliary thread comb cutter table. The tool table can be equipped with various attachments, such as a rotary cutter assembly, a deburring unit, and a grinding device, enabling centralized processing and improving overall workflow efficiency.
