PINNACLE Pinnacle AX 320 VERTICAL MACHINING CENTER

Technical Description

The PINNACLE Pinnacle AX 320 Vertical Machining Center is a robust 5-axis CNC machine designed for high-precision applications in aerospace, automotive, military, and general manufacturing sectors. It features a Ø12.6 (320 mm) circular table with a maximum load capacity of 330.69 lbs in both 0° and 90° orientations, supporting workpieces up to Ø16.54 x 11.81 inches. The machine offers extensive travel ranges of 25.98 x 24.02 x 24.02 inches (X, Y, Z axes) and includes A and C rotary axes with a tilt range of -120° to +30° and full 360° rotation respectively, allowing complex multi-axis machining. The spindle supports multiple speed ranges: direct drive speeds up to 15,000 rpm and built-in spindle options up to 24,000 rpm, powered by a 12.06/16.1 hp main motor rated for continuous and 30-minute operation. Rapid feed rates reach 98.43 ips on X and Y axes, with a feed rate of 32.81 ips. Tool storage accommodates 24 tools (expandable to 30 or 40) with max tool diameter of 3.54 inches and length of 11.81 inches. The machine has a compact footprint of 104.72 x 87.80 inches and weighs approximately 14,330 lbs. It requires a 380 V power supply, air pressure of approximately 85 psi, and hydraulic supply at 57.03 psi. The structure is made from stress-relieved Meehanite cast iron for high rigidity and vibration dampening. The spindle nose to table distance ranges from 1.97 to 23.82 inches, facilitating versatile setups. The AX 320 offers high-speed linear feed, precise rotary torque—7.38 Nm on main axes—and substantial coolant capacity, making it ideal for demanding, high-accuracy machining tasks.
