DMC Machine Tools’ DM V series of vertical machining centers includes the DM 42V, 42VL, 50V, 52VL, 65V and 65VL, which are said to provide increased reliability for heavy-duty operations on larger workpieces. The high-precision VMCs feature a belt-type spindle with speeds ranging to 8,000 rpm, and a 12,000-rpm spindle is available as an option.
An automatic toolchanger holds 24 to 40 tools, depending on the model, and achieves tool-to-tool change time of 1.3 sec. Pallets accommodate loads ranging from 661 to 2,866 lbs, depending on the model. Rapid traverse rates in the X, Y and Z axes are 1,890 × 1,890 × 1,417 ipm in the DM 42V model and 1,417 × 1,417 × 1,181 ipm in the other models. Travels range from 24.41" × 16.54" × 20.08" to 59.06" × 25.59" × 14.80".
The VMCs feature a rigid bed with low center of gravity and a wide-column design. Colum width measures 41.73" and the spindle height from end is 42.52". A right- or left-type spiral chip conveyor is standard, but a front-facing spiral chip conveyor is also available as an option. A coolant shower clears chips from the splashguard. The VMCs also are equipped with a screw conveyor, coolant and lubrication systems, a 10.4" TFT LCD color monitor, and a FANUC 0i-MD CNC.
