Vertical machining for complex geometriesSeptember, 03 2012
New from Doosan, the DNM vertical machining center produces parts up to 15.7 in. diameter by 13.2 in. high, and now, with a factory installed, fifth-axis rotary-turning table, can produce complex geometries with shorter cycles and greater accuracy.
The turning table is constructed with double-lead worm and pinion gears that mesh fully along the length of the teeth. A pneumatic clamping device, working in conjunction with the table, increases clamping forces by 250% and indexing speeds by 50%. The 13.8 x 13.8 in. table is supported in all positions, with no table overhang, enabling high accuracy, even when machining far from the tilting axis. The maximum load is 550 lbs.
The DNM350/5AX is constructed on a sturdy fine-grain Meehanite casting. High speed, linear motion guide ways are used on all axes. The DNM350/5AX will be displayed and demonstrated at IMTS exhibit South Hall, booth S8100.
