Heavy-Cutting 3-Axis Machining Center · SKU WMT-VMC855-HD
Reinforced wide-span structural casting and 45 mm 3-axis roller linear guideways for aggressive steel roughing and deep mold cavities.
The WMT VMC855 is a heavy-duty evolution of the 850-class vertical machining center, featuring an expanded 855 × 550 × 550 mm travel envelope, a wider 1,000 × 550 mm worktable rated for 1,000 kg, and a 6,300 kg reinforced HT300 cast-iron frame. Unlike standard VMC850 machines, the VMC855 utilizes oversized 45 mm heavy-load roller linear guideways across all three axes (X, Y, and Z) and a widened column base, increasing structural damping by 28% during deep pocket milling in P20, H13, and 4140 tool steels. Powered by a high-torque 15/18.5 kW BT40 spindle (or optional BBT40 dual-contact spindle), it maintains ±0.003 mm repeatability under heavy cutting loads.
