A new innovation, EcoAir, is now available from British CMM manufacturer LK Metrology to lower the carbon footprint of its products. The company can incorporate the technology into new machines built at LK’s Derbyshire factory or retrofit EcoAir to existing CMMs. It is possible to upgrade any make of CMM providing it features an LK NMC300 controller, which is also available from the manufacturer as a retrofit.
Connected to the machine’s air filter set, the EcoAir automatic shut-off unit interrupts the supply of compressed air to the CMM’s air bearings when the machine is idle, reducing consumption by up to 95% and leading to substantial energy and cost savings. The period of inactivity that triggers shut-down is adjustable to as little as one minute. The CMM remains ready for action, however, and the flow of compressed air resumes automatically when the CMM resumes action, in either manual or CNC mode.
Such power-saving devices help manufacturers to meet regulatory requirements for energy efficiency and support corporate social responsibility initiatives, while reaping the financial benefits of reduced electricity consumption. Other ecological measures introduced over the years by LK include a reduced thickness of the air bearing film needed to maintain smooth, accurate movement of the machine elements over their guideways. This design not only cuts air consumption when the CMM is in use but also offers 3.5 times higher stiffness than standard air bearings due to their wrap-around design. The major benefit is improved accuracy of measurement thanks to higher resistance to dynamic forces, particularly when tactile scanning or using long probes.
