The 2014 SMTCL VMC850B is a heavy-duty CNC vertical machining center built around a 1000 × 500 mm T-slotted table, 33.4 inches of X-axis travel, 22 inches of Y, 25.5 inches of Z, and a 10,000-RPM cartridge spindle on a CAT 40 taper driven by a 20 HP motor. Configured with a 24-position double-arm random-access ATC, a 4th-axis SMTCL CNC-250R rotary table (Golden Sun GSA), 20-bar through-spindle coolant, spindle chiller, spindle air blow, and the Fanuc Series 0i-MD control with Custom Macro B, 200-block advanced preview look-ahead, manual pulse generator pendant, embedded 100 Mbps Ethernet, and 320 M of program storage with 400 registered programs, this VMC is set up for prototype, fixture, and short-run production work in steel, aluminum, and exotics. Equipped with a kurt-style precision vise on the table and a lift-style chip auger added to the machine.
Compared to the open-frame, lower-rigidity VMCs typical of the entry-level segment, the VMC850B's box-style construction and SMTCL's heavier cartridge spindle deliver meaningful damping for finish quality at production feeds. The 4th-axis CNC-250R rotary, advanced preview look-ahead, and Fanuc 0i-MD control package layered on top match the modern in-process workflow shops expect on a current-generation VMC, while the under-$30K buy on a 2014 build with a 4th-axis already integrated significantly undercuts comparable USA listings — most current 2014 VMC850B asks land in the $27.5K–$74K range without the rotary or vise package.
