JOHNFORD VMC-850 VERTICAL MACHINING CENTER

Technical Description

This CNC machine features a robust 7.5 kW AC spindle motor capable of reaching speeds up to 8,000 RPM, delivering high-speed precision machining with constant power output above 4,000 RPM to ensure stable speed and excellent surface finish. The spindle holds 24 automatic tool changes (ATC) and supports three-axis control, enabling versatile multi-axis milling operations. The control system is powered by a FANUC 0i-MD CNC controller, which supports up to three simultaneous axes with advanced digital servo control, nano-interpolation for smooth surface finishes, and a flexible range of manual and automatic functions including rigid tapping, feed and speed overrides, and tool compensation. The controller also features automatic data backup and Ethernet connectivity for enhanced reliability and integration. The machine weighs approximately 12,000 lb, ensuring solid stability during heavy-duty machining operations. This configuration suits applications requiring high precision, responsiveness, and efficient tool management in small-to-medium batch production or custom part manufacturing contexts.
