LUNAN VMC850 VERTICAL MACHINING CENTER

Technical Description

The LUNAN VMC850 Vertical Machining Center features a robust working envelope with axis travels of 31.5 inches in X, 19.7 inches in Y, and 23.6 inches in Z, supported by a spacious table measuring 41.3 inches long by 19.7 inches wide. Designed for precision machining, it supports a maximum worktable load around 500 kg (1,100 lbs) and utilizes a BT40 spindle taper capable of speeds up to 8,000 rpm, powered typically by a 7.5 kW motor. The machine employs high-quality components including Taiwan-made ball screws and linear guides to ensure smooth, accurate axis movements with positioning accuracy around ±0.005 mm and repeatability near ±0.003 mm. Its structure uses precision-cast resin sand construction for rigidity and thermal stability. The VMC850 is equipped with a 24-tool automatic tool changer, enabling efficient tool switching with minimal downtime. Rapid traverse rates reach up to 24 m/min on X and Y axes and 20 m/min on Z, facilitating high productivity across operations like milling, drilling, tapping, and boring. Additional features often include automated lubrication, cooling systems, handwheel manual operation, and optional chip conveyors, enhancing reliability and ease of use in mold making and mechanical parts manufacturing. Overall dimensions approximate 2750 mm by 2300 mm by 2300 mm, with a machine weight near 5,300 kg, reflecting its robust industrial build capable of handling complex precision machining tasks. This model is suitable for a range of manufacturing sectors requiring versatile, precise, and efficient vertical machining centers.
