GM CNC introduces heavy duty vertical machining centres

By Bhalchandra Chorghade, Editor, CNCTimes.com

If you are looking for a machining centre that exceeds all heavy-duty cutting performance demands, GM CNC now has the new Victor Vcenter G-series of machines available. High stability and rigidity are the foundation blocks of this range.

The Victor Vcenter G-series from GM CNC is designed for high material removal rates and applications where manufacturers are processing particularly challenging materials. To ensure flexibility, the company has a G135 series in stock with a 4th-axis unit.

Like all machine tools manufactured by Victor, build quality and rigidity are assured with the Victor Vcenter G-series line-up. The powerhouse 3-axis G-series is available in three size variants to meet the diverse demands of the industry. Unlike its competitors in the mid-sized VMC market segment, the G-series incorporates a meehanite casting with a wide base A-Frame design, a wide span column, four boxways and screw removers with a wide boxway.

The three G-series variants include the G105, G135 and G165. The smaller G105 provides X, Y and Z axis travel of 1050 by 600 by 600 mm and this stretches to a spacious 1650 by 850 by 900 mm on the largest G165. This exceptional freedom of movement is matched by the accommodating bed sizes of 1100 by 600 mm (G105), 1400 by 700 mm (G135) and 1700 by 800 mm (G165). Furthermore, the robust nature of the range permits the loading of components up to 1200, 2200 and 2,500 kg respectively for the three machines.

Common features on all three machines include a powerful gearhead spindle design that generates a power output of 18.5 kW with a torque level of 498 Nm. Developed, manufactured and built in-house by Victor, the 6000 rpm gearhead design spindle retains maximum torque levels throughout the speed range. This makes the Vcenter series ideal for machining hard materials and exotic alloys with material removal rates that far exceed that of any other machine in its class. Adding to this, the G-series incorporates a Big-Plus BBT-50 spindle taper that guarantees dual face and taper spindle contact for industry leading precision, repeatability and performance. This power and stability enhance precision levels with a platform that also generates surface finishes and industry-leading component quality.

The Victor Vcenter has an automatic tool change unit with 24 tool capacity and the option for 32 or 40 tool positions; all positions can accommodate tools up to 15 kg. The axis feed motor generates 3 kW of power on all axes with a rapid feed rate of 20 m/min and axis acceleration of 0.28 G, which is driven through extremely large 50 mm diameter ballscrews to further enhance stability.

As standard, the Victor Vcenter G-series is supplied with the latest Fanuc 0i-MF Plus CNC control unit, fully enclosed splash guarding, spindle oil cooler, screw-type chip removal, bottom guarding for coolant flushing, rigid tapping, 3 step warning lights, auto power off and levelling pads.

Like every Victor machine that is available from GM CNC, the Vcenter G-series is available with a host of options to meet the exact requirements of the end user. Options include a 4th and 5th axis interface for increased flexibility, 32 or 40 tool ATC, probing for automatic tool and component measuring. Additional options include through spindle coolant, chip conveyor with cart, air conditioning for the electrical cabinets and linear scales for enhanced precision levels. Customers can also select a table shower, oil skimmer, automatic doors, air and coolant guns and much more.
