By Larry Pellegrini, Sr. Director-Operations

Murata Machinery USA offers customers a great production turning
machine for parts that require tailstock support. Typical automotive part
applications for this machine are transmission support shafts and
constant velocity joints (CVJ). To minimize cycle time and maximize
production, the MJ200G has two turrets capable of working on the part simultaneously.

Tailstock:
The MJ200/G tailstock offers a servo controlled z-axis and a programmable vertical axis. This allows for
quick and accurate positioning of the tailstock spindle to rigidly support the part during cutting and for quick
positioning of the tailstock for clearance during automatic load and unload of parts. Standard work size
envelope for the MJ200/G is Ø150mm by 200mm in length.

Twin Turrets:
Two, independent ten station turrets on the MJ200/G allow
for simultaneous machining of the part. Cycle time can be
dramatically reduced when compared to single tool turning.

Gantry Loader:
Standard on the MJ200/G mac hi ne is the Murata designed
and manufactured 3-axis CNC gantry loader. Murata
Machinery is a proven leader in the field of turning machine
automation, and the gantry loader on the MJ200/G machine
is an extension of this advanced and robust technology. The
gantry loader assures consistent loading and unloading of
parts to the machine workholding, shift after shift, week after
week, year after year.

The flexibility and programmability of the gantry also allows our customers to add features like input and
output chutes or conveyors, part orientation, part wash station, and automatic post process gauging. All
these features can have the part loaded and unloaded with the machine gantry. For more information on
