Turning/Milling for Contract Machine Shops

The G550T horizontal machining center from Grob Systems operates in the A & B axes and can also turn parts at 800 rpm to open up new opportunities for machining of wheels, certain housings and parts requiring both turning and milling in just one set up.

Grob Systems, Inc., Machine Tool Division (Bluffton, OH) offers the new G550T horizontal machining center for the first time in North America. This high-precision machine features an innovative design that simultaneously machines parts in 5-axes, as well as turning them. A unique feature is its table that operates in the A & B axes and can also turn parts at 800 rpm to open up new opportunities for manufacturers to machine wheels, certain housings and parts requiring both turning and milling in just one set up.

The horizontal spindle 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 provides excellent front and side access for part loading, as well as optimized chip flow. Its compact design has a small footprint.

The 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 (1020 mm) in the Z-axis. The table has maximum rotation of 240 deg in the A and 360 deg in the B axes, as well as 800 rpm turning capability. The table is driven by a torque motor for turning and is capable of various clamping systems, depending on part requirements.  Linear glass scales are provided on all axes.

The G550T provides a high level of flexibility, ideal for general machining and configurable to the agile needs of contract machine shops while its proven longevity, rigidity and precision are suitable for high-volume cell and system tasks. The G550 model will also be exhibited, with engineering specifications and performance data for the company’s full range of G-Series precision machining centers and automation systems. www.grobgroup.com
