Pinnacle BX300 VERTICAL MACHINING CENTER

Technical Description

The Pinnacle BX300 Vertical Machining Center is a high-performance 5-axis CNC machine featuring a vertical spindle with an ISO #40 taper and a maximum speed of 15,000 RPM powered by a 24 HP motor (30-minute rating). It includes a 17.7" x 17.7" standard table, with an optional larger table size of 51.18" x 24", supporting workpieces up to 660 lbs. The machine offers 5-axis capability with X, Y, and Z travels of 44.88", 24.02", and 31.89" respectively, complemented by a B-axis rotary swing of 240°. Rapid traverse rates reach up to 1,414 inches per minute on all three linear axes, enabling fast, precise positioning. Tooling is managed via a 30-tool automatic tool changer (ATC) with an optional 60-tool capacity, optimizing tool change efficiency and production uptime. The rotary table is standard, enhancing multi-axis machining flexibility. The BX300 employs a rigid Meehanite cast iron base for stability and vibration dampening, ensuring high accuracy and surface finish. It incorporates pneumatic balance for smooth Z-axis movement and a spindle oil cooler to maintain thermal stability and prolong spindle life. High-speed roller linear guides and precision ballscrews drive the axes, offering contour-accurate, rapid, and stable motion. The machine is compatible with advanced CNC controls, such as HEIDENHAIN TNC640, supporting complex simultaneous 5-axis operations for intricate parts. This machining center is ideal for industries requiring complex multi-sided machining with high precision, robustness, and extended tool capacity, making it suitable for aerospace, automotive, and mold manufacturing applications.
