PRATIC PA VERTICAL MACHINING CENTER

Technical Description

The PRATIC PA Vertical Machining Center is a precision 3-axis CNC system engineered for high-volume production and complex aluminum profile machining applications. Featuring an impressive 250-inch X-axis travel paired with 400-inch Y and Z-axis traverses, this machine delivers exceptional versatility for large-scale workpiece processing. The spindle operates at a maximum speed of 12,000 RPM with a BT30 taper, powered by a 5.5 kW motor that provides excellent dynamic performance and rapid acceleration for aggressive material removal. The 55 x 32-inch worktable accommodates substantial components and supports heavy loads, making it ideal for aerospace, automotive, and custom furniture manufacturing. The 16-pocket UFO-type automatic tool changer enables rapid tool changes in approximately 3 seconds, minimizing production downtime and maximizing efficiency. Rapid traverse rates reach 50 m/min on the X-axis and 36 m/min on Y and Z-axes, with cutting feed rates up to 15,000 mm/min for optimized cycle times. The machine achieves positioning accuracy of 0.02 mm on the X-axis and 0.015 mm on Y and Z-axes, with repeatability accuracy of 0.01 mm, ensuring consistent precision across production runs. Integrated with either FANUC or SIEMENS CNC control systems, the PA series offers advanced programming capabilities and user-friendly operation. The robust construction features a high machine bed design that effectively prevents coolant splashing and protects critical components like guideways and ball screws, significantly extending machine reliability and service life.
