NC SWIVEL HEAD AND ROTARY TABLE ADD MULTI-APPLICATION
FIVE-AXIS DYNAMICS TO HECKERT HEC630D U5 MT
Starrag UK’s new addition to the Heckert range of high-speed Dynamic machining centres, the larger capacity HEC630D U5 MT, offers up to five-axis machining capability utilising a NC swivel head, plus turning/turn-mill operations via a high-speed (900 revs/min) rotary turning table option. The NC rotary table provides multi-face, one-hit machining including interior, exterior and ‘straight’ turning tasks.
With X, Y and Z axis travels of 850 mm, 700 mm and 850 mm, respectively, and corresponding rapid axis traverse rates and feed rates of up to 100 m/min, the new machine’s focus is clearly on reduced cycle times and single set-up finish machining with a machining accuracy of six microns over the full linear axis strokes.
Maximum productivity is also addressed by rapid tool change from the standard 60-tool chain magazine (80-tool optional) for tools up to 160 mm diameter and 400 mm long – chip to chip is just 2.7 secs – and the 1,000 kgs capacity of each of the machine’s two pallets. Pallet change takes only 9.5 secs. The machine is offered as standard with a 24 kW spindle; a 37 kW/350 Nm torque option, with reinforced column, can be supplied for heavy-duty applications.
