JOHNFORD SV-48 VERTICAL MACHINING CENTER

Technical Description

The Johnford SV-48 Vertical Machining Center is a robust and versatile CNC milling machine designed for heavy-duty industrial applications. It features a powerful 11 hp spindle motor capable of reaching up to 10,000 RPM, supported by a 24-tool automatic tool changer (ATC) to enable efficient multi-tool operations. The worktable measures 27.6 inches in width and 51.2 inches in length, providing a substantial workspace for large parts and complex machining tasks. The machine’s overall dimensions are approximately 122 inches wide, 134 inches deep, and 117 inches high, with a substantial weight of 20,900 lbs, highlighting its rigid Meehanite cast iron construction that ensures minimal vibration and excellent precision during machining. This vertical machining center typically includes FANUC CNC control systems, ensuring precise and reliable multi-axis machining capabilities over X, Y, and Z axes with ample travel (typically around 48" x 28" x 25" for similar Johnford models). The spindle uses a BT40 taper, making it compatible with a wide range of tooling standards. It is equipped with features such as coolant through spindle to enhance tooling life and machining accuracy. The SV-48 is well suited for machining large molds, aerospace components, and heavy automotive parts where high rigidity, stability, and repeatability are critical. Its design incorporates large box ways and a heavy-duty gearbox, optimizing load capacity and torque delivery for various milling, drilling, and tapping operations in demanding manufacturing environments.
