LUNAN VMC850S VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a **BT40 taper spindle** capable of rotating at **8,000 RPM**, providing robust and precise machining performance suitable for medium-duty milling operations. It offers a **worktable sized 41.3 inches in length by 19.7 inches in width**, accommodating sizable workpieces with ample support, while the **table width matches the Y-axis travel at 19.7 inches**, ensuring efficient material handling. The machine’s axes travel distances are **31.5 inches (X-axis)**, **19.7 inches (Y-axis)**, and **23.6 inches (Z-axis)**, enabling versatile 3-axis machining across a broad range of part geometries. Control is managed via an integrated **CNC system** allowing automated, precise toolpath execution and repeatable positioning accuracy. The BT40 spindle taper is industry-standard, symmetric for excellent balance and rigidity at high speeds, which minimizes vibration and enhances tool life. The machine’s configuration supports high-speed milling with stable torque transmission, suitable for milling, drilling, and tapping operations on metals and other materials. The relatively large table and travel dimensions cater to medium-sized parts common in mold making, aerospace, and automotive prototyping. This CNC mill combines a reliable spindle taper, moderate spindle speed, and sufficient axis travel along with CNC control, delivering a balanced package for efficient, accurate machining of complex components and prototyping tasks in industrial manufacturing environments.
