The PMT moving gantry system provides the durability and strength needed for machining large beams utilized in sports arenas and other large facilities. CMS' PMT machining center was developed due to request of engineers and facility designers and in part spurred by safety codes in various worldwide locales which recognize that wooden beams support longer in a fire than steel beams. This 5 axis CNC machining center for large wooden beams handles wood beams up to 60 meters in length and longer. The loading of the PMT moving gantry is done manually with a crane, as the wood parts to be machined are immense in size and weight. Once loaded a laser verifies the orientation of the beam, in order to adjust the CNC program within the working envelope.
