Reference system for Wire EDM machining. The standard range.

THE MATERIAL REMOVAL CAPACITYOF THE WIRE EDM MACHINES hasbeen significantly improved over the past decades. Thetable shows values obtained by experience in coarsemachining.So over the past 25 years, the material removalcapacity has increased almost by a factor of 15. Finefigures, but the question is: does the user exploit thisincreased capacity, or is it a hidden resource?Material removal mm 3 /min300500Introduction25020080150351980 1985 1990 1995 2000 2005Tooling-up time in astationary machineOVER THE SAME PERIOD tooling-uptimes have remained largely unchanged. Let us takean example with an ordinary machining operation of4200 mm 3 .1980: 4200 mm 3 /35 + 30 min tooling-up time inthe machine = 150 minutes’ machine time.2005: 4200 mm 3 /500 + 30 min tooling-up timein the machine = just over 39 minutes’machine time.Active machining time39Four times as fast, but far from the 15-fold capacityincrease offered by the machine! So only 25% of thecapacity increase offered by investing in a modernwire EDM machine is exploited.1985 1990 1995 2000 2005IF YOU HAD HAD THE FORESIGHTin 1980 to equip your machine with the System3R reference system for pre-setting away from themachine, the figures look like this.1211980: 4200 mm 3 /35 + 1 min tooling-up time inthe machine = 121 minutes’ machine time.Tooling-up time in astationary machine2005: 4200 mm 3 /500 + 1 min tooling-up time inthe machine = just over 9 minutes’machine time.25 years successful technical development of themachines has meant a huge potential increase inproductivity in wire EDM machining. Do you get thefull benefit of this potential? 39 or 9 minutes for thesame machining operation? The choice is yours.Active machining timeCan your company afford to work without theSystem 3R reference system?1985 1990 1995 2000 200595
