IMTS 2012: New HMC with Turning and Milling Capabilities

Sept. 9, 2012
Three linear, two rotary axes permit five-sided machining five-axis simultaneous interpolation. Table operates in the A and B axes

GROB Systems Inc., Machine Tool Division will demonstrate a new horizontal machining center for the first time in North America, the G550T.  It’s a high-precision machine characterized by a design that allows it to machine parts in five axes, as well as turn them, simultaneously. The one-of-a-kind feature of the machine is its table that operates in the A and B axes, and also can turn parts at 800 RPM.  This turning capability establishes opportunities for manufacturers to machine wheels, certain housings, and parts that require both turning and milling in just one set up.

The G550T model’s horizontal spindle design provides access to the workpiece on all faces, including the inside of hollow parts, in addition to using the maximum tool length.  The three linear and two rotary axes permit five-sided machining as well as five axis simultaneous interpolation.  The G550T design also provides excellent front and side access for part loading as well as optimized chip flow.  Its compact design has a small footprint.

The G550T machining strokes are 31.4 in. (800 mm) in the X axis, 37.4 in. (950 mm) in the Y axis, and 40.1 in. (1,020 mm) in the Z axis.  The table has maximum rotation of 240° in the A and 360° in the B axes, as well as it 800 RPM turning capability.  The table is driven by a torque motor for the turning feature and will be capable of various clamping systems, depending on part requirements.  Linear glass scales are provided on all axes.

The GROB G550T provides a high level of flexibility that makes it ideal for general machining and configurable to the agile needs of contract machine shops, while its long service life, rigidity, and precision are suitable for high-volume cell and system tasks.
