At the end of every cycle in all three machines, the trunnion carrying the fixtured components is programmed to come to rest at 45 degrees. It encourages swarf and coolant to fall away and minimises the need to use an air gun to clear the machining area. Additionally, work is presented more ergonomically to the operators, enhancing production efficiency. The high speed of the α-D21LiA5 ROBODRILLs derives from an industry-leading specification that includes 1.5 g acceleration to 54 m/min rapids in all linear axes, up to 30 m/min programmable feed rates and 1.6 seconds tool change time, chip-to-chip.
Working volume is 700 x 400 x 330 mm and the machines at Concentric have been equipped with a swarf conveyor and oil mist extraction. Mr McFall confirmed that the machines have proved reliable since installation, producing components to ± 10 microns tolerances, and that FANUC has provided excellent programming support and training.
