AMERA SEIKI VAS-3 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a robust 40-inch X-axis, 20-inch Y-axis, and 25-inch Z-axis spindle stroke, providing extensive work envelope flexibility. The table measures 48 inches in length and 20 inches in width, capable of supporting loads up to 3,700 lbs, ensuring stability for heavy-duty machining. The spindle offers versatility with a standard CT 40 taper, with BT 40 taper available as an option, operating within a speed range of 30 to 7,500 RPM. Power is supplied by a 20 HP AC spindle motor with a maximum torque of 275 ft-lb at 450 RPM, transmitted through a 2-speed geared system with high and low gear ratios of 1:1 and 4:1 respectively. Movement across the X, Y, and Z axes is driven by 3 HP motors with a maximum thrust of 2,850 lbs, employing 1.417-inch diameter ball screws and rigid box-way slideways to ensure precision and durability. Rapid traverse rates reach 944 inches per minute, with maximum cutting feed rates of 394 inches per minute, optimizing machining speed and efficiency. The tool carousel holds up to 24 tools, accommodating tool diameters up to 3.5 inches, lengths up to 11.8 inches, and weights up to 12 lbs, with a tool change time of 5.9 seconds. Electrical requirements include 480V, 3-phase power at 60 amps, with the machine currently wired for 230V. Pneumatic requirements demand 100 PSI air pressure. A 40-gallon coolant system supplies 10 GPM flow rate to maintain optimal cutting temperatures. Overall dimensions are 118 inches wide, 110 inches deep, and 120 inches high, weighing approximately 13,000 lbs, and providing a 48-inch wide door opening for easy access. The machine’s construction and specification support heavy-duty precision milling with high-speed operation and rapid tool changes for efficient production.
