KENT KVR-4020A VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features robust axis travels of 39.4 inches (X), 19.7 inches (Y), and 20.5 inches (Z), supporting large and complex workpieces on a 43.3 x 19.7-inch table with a 1760 lb load capacity. The table has five T-slots (0.71 x 3.94 inches) for versatile clamping and positioning, elevated approximately 37 inches from the floor. The spindle offers speeds up to 10,000 RPM with a powerful 15 hp motor delivering 52 ft-lb of torque, enabling efficient cutting across various materials. Tool management includes a 24+1 tool carousel supporting tools up to 3.0 inches in diameter, 11.8 inches length, and 12.1 lb weight, with rapid tool change times of 1.3 seconds to maximize productivity. Axis drive motors are rated at 4.0 hp for each direction, with rapid traverse rates of 1417 in/min (X and Y) and 1260 in/min (Z), and a cutting feed rate up to 590 in/min, enabling fast and precise machining. Linear roller-type guideways with diameters of 1.2 inches (X/Y) and 1.4 inches (Z), combined with a 1.26-inch diameter ball screw, ensure rigidity and positioning accuracy of ±0.0002 inches. The spindle-to-table clearance ranges from 3.1 to 23.6 inches for accommodating diverse part sizes. Power requirements specify 20 KVA at 220V, three-phase, supplemented by 80 psi compressed air supply. The machine’s coolant and lubrication systems include 60-gallon and 0.5-gallon tanks, respectively. Dimensions of the machine footprint are 12.3 x 12.1 feet with a maximum height of 8.9 feet, and a net weight of 9,636 lb, reflecting a heavy-duty construction suited for precision industrial milling applications. Shipping dimensions and weight are compactly managed at 9.7 x 7.5 x 8.3 feet and 10,900 lb.
