The highlight of the GM-2 is its powerful 30 hp (22.4 kW) inline direct-drive spindle. This is the same high-performance spindle used in our VF, EC, and UMC Series mills – now available to tackle your biggest jobs on this large, open-frame machine.
The GM-2 comes standard with an 8100-rpm spindle that is outstanding for all-purpose machining work. For high-speed machining operations and high feedrates with small tools, optional 10,000-rpm and 15,000-rpm high-speed spindles are available. These spindles are capable of high rpm operation, without sacrificing low-speed torque or high-speed power.
The GM-2 also incorporates the robust spindle head assembly from our highly successful UMC-1000, which uses linear guide trucks with a much higher load rating for added rigidity, transforming our very successful large-frame gantry router into a high-performance gantry milling machine.
This change also means that high-productivity options like Through-Spindle Coolant and Through-Tool Air Blast are available on the GM-2.
