SMTCL VMC850P VERTICAL MACHINING CENTER

Technical Description

The SMTCL VMC850P is a high-performance vertical machining center designed for precision machining with a work envelope of 33.46" (X) by 20.47" (Y) by 21.65" (Z). It features a robust BT40 spindle capable of 8,000 RPM, optimized for both rough and finish machining on mold components, mechanical parts, and intricate profiles. The worktable measures 19.68" wide by 39.37" long, supporting loads up to 500 kg, with five T-slots (18 mm wide, 100 mm pitch) for secure workpiece mounting. The machine employs a rigid "pyramid" style column and full ribbed casting with linear guideways on all three axes for enhanced stability, vibration damping, and precision. Axis travel utilizes high-precision double-anchored ball screws with direct servo coupling, minimizing thermal expansion and improving repeatability (positioning accuracy ±0.005 mm, repeatability ±0.003 mm). Rapid traverse rates reach up to 48 m/min on the X and Y axes and 32 m/min on Z, enabling efficient material removal and cycle times. The VMC850P includes a 24-tool arm-style automatic tool changer with 2.5-second tool change times, maintaining machining continuity. Additional features include an integrated lubrication system, coolant through spindle option, chip conveyor, and a labyrinth-style protective cover to prevent contamination. The spindle box design enhances rigidity via improved contact ratio with the column, and a Z-axis weightless structure ensures stable vertical positioning during high-speed operations. Overall, this VMC850P is engineered for reliability, precision, and versatility in high-demand CNC milling applications requiring tight tolerances and consistent performance.
