The higher the idle speed of the machine, the tougher the body and frame
should be. If the load on these elements exceeds the one for which they are designed, then this is fraught not only with undesirable vibrations during operation, but also with a reduction in the service life of the machine.
Therefore, the frame and body of machine determine its designed speed. For example, Wattsan E-series machines are designed for idle movements at a speed of 80 m/min. and they have an all-welded frame with a cross-section thickness of 6-8 mm and Mitsubishi engines of 1 kW, and Wattsan S-series machines are designed for a travel speed of 120 m/min., the cross-section thickness of the all-welded frame of this series is 8-10 mm, and the engine power is already 1.5 kW.
Virmer recommends its customers to follow the principle of sufficiency — that is, to choose equipment strictly for the tasks and not to overpay for unnecessarily expensive components.
At the production stage, the frame of the laser cutting machine must be tempered in a special furnace with strict temperature control in order to relieve the stress of the metal. Without this procedure the frame will lose its geometry and the precision characteristics of the machine will be spoiled without the possibility of their restoration.
