Mitsui Seiki is showing its newest, precise, five-axis vertical CNC machining center at WESTEC 2006, March 27-30 in Los Angeles, in North-South Machinery’s booth 3532. Specifications of the "Vertex 550-5X" include a compact footprint of about 7 feet wide by 11 feet long (2,000 mm x 3,300 mm). The X, Y, Z-axes work envelope is 21.6 inches x 23.6 inches x 17.7 inches (550 mm x 600 mm x 450 mm). All three move quickly at 1,890 ipm. With the A and C rotary and tilt axes, the Vertex 550-5X provides a total of five integrated axes of motion for virtually one setup machining of complex workpieces requiring maximum rigidity and accuracy. Prismatic parts in the aerospace, automotive, medical, dental, and mold and die industries are ideal to be produced on this machine. The machine at WESTEC will have a 15,000-rpm spindle (25,000 rpm is optional). The machine also features the Fanuc 31i control with enhanced features for precision high-speed, five-axis applications, including dynamic five-axis fixture offset–an exclusive on Mitsui Seiki machines.
The Vertex has a casting design which provides an ultra rigid machine structure. Another key feature is a unique gear drive system for the A and C rotary axes, which provides high speed radial performance (A-30 rpm; C-50 rpm), and overall drive system stiffness. Further, the trunnion tilt axis, A, has ample dual side support construction bolstering rigidity even more. Most VMCs on the market only support the rotary axis on one side, or both sides with small support areas. Also on the Vertex, the linear axes move the spindle only. The motion of the workpiece is by the rotary axes only, offering improved control of machine dynamics.
Mitsui Seiki’s tradition is to build rigid and ultra precise metal cutting and grinding machines. The Vertex 550-5X’s geometric accuracy is carefully monitored in the tightest a temperature-controlled factory environment in the world. The machine features a bed design that allows large part capacities with a small floor space requirement. This unique "box in a box" design provides superior rigidity and stiffness that typically is not available in machine of this size. The linear guides way mounting surfaces, both linear and rotary, are hand-scraped, achieving tolerances which would be impossible to achieve on surfaces that are machined and ground. This engineering and construction capability, coupled with a newly designed machine, provides users with enhanced competitive advantages over traditionally designed machines.
