Colgar FVG Hydrostatic vertical gantry boring and milling machines

FVG is the series of vertical hydrostatic boring and milling machines and completes the already vast range of Colgar's horizontal machines.

The world of mechanics is moving towards ever more complex and voluminous components. The FVG series expertly combines a large number of functions, and the result is so satisfactory that we can herald the success of this solution in innumerable applications, both for the model with a fixed cross-beam and that with a mobile cross-beam.

The great possibility of being able to effectively work on five sides is combined with numerous custom accessory heads, heads with continuous axes, and turning tables.  

Given the large dimensions, the machine could not do without the most innovative systems for cross-beam flexure compensation, adaptive control with three-directional sensors on the ram, and hydrostatic oil and coolant temperature control.  

The ram, completely covered with hydrostatic oil, contains the transmission device, and some specific technical solutions allow the even distribution of residual heat generated by the motors.  

The FVG series offers the best performance the chip removal market is looking for.

The FVG series can be configured with a fixed or a mobile cross-beam. In both cases, the ram is covered and guided on its four corners by the means of hydrostatic oil and counterbalanced by dedicated hydraulic systems. In the configuration with the mobile cross-beam, the side columns as well as the bed have a gantry movement. Each column has a hydraulic counterweight, a ball screw, and an optical scale used to handle the cross-beam as the positioning and working axis. 

The cross-beam is the key element of the machine; its ground guides allow excellent gantry geometry, also thanks to the real-time flexure compensation with various setups based on the ambient working conditions and hence the temperature. During design, careful attention was paid to technical details not only to provide high performance but also to offer a better working environment, for example: the double operator footboard with master and slave controls, the remote-controlled pushbutton panels, the surveillance cameras, and the possibility of completely covering the foundations, giving the entire gantry a floating effect but at the same time allowing the operator to position the workpiece in complete safety.

In its maximum configuration, the machine may be considered multi-tasking with the following possibilities: automatic control of different working areas; the rack magazines can be positioned on the edge of or outside the wall, both with single and double tool change grippers; automatic accessory change with the possibility of a buffer onboard and an external refresh. The large structure and the powerful spindle allow deep removal passes but also excellent finishes with high cutting speed. FVG is suitable for milling, drilling, tapping, turning, and boring on any type of metal.
