The high production Quicktech i-60 Ultimate CNC turning center from Absolute Machine Tools performs complete machining of medium diameter bar stock, including complex milling operations, using two turning spindles, two milling spindles and two B-axes for a total of ten axes and up to 49 tools. Bar capacity for the 15 hp main spindle is 60 mm and 30 mm for the 7.5 hp sub-spindle. Both main and sub-spindles feature full continuous C-axes and are synchronized for fast, accurate part transfer. The comprehensive tooling system provides outstanding part-making flexibility. (first view)

Absolute Machine Tools, Inc. (Lorain, OH) is the exclusive North American distributor of the Quicktech i-42 Ultimate and i-60 Ultimate high production CNC turning centers that permit complete machining, including complex milling operations, of medium diameter bar stock. With two turning spindles, two milling spindles and two B-axes, these machines provide a total of ten axes and capacity for up to 49 tools. Bar capacity for the 15 hp main spindle is 42 mm for the i-42 (60 mm for the i-60), and 30 mm for the 7.5 hp sub-spindle on both machines. Both main and sub-spindles feature full continuous C-axes and are synchronized for fast, accurate part transfer. The comprehensive tooling system provides outstanding part-making flexibility.

A four-axis (linear X,Y, Z and rotating B axes) gang-type vertical tool post serves each spindle. The main tool post has six OD turning tools, five ID turning tools, and 12 live tools. The sub tool post features five OD turning tools, nine ID turning tools, and 12 live tools. Each tool post has a Y-axis for off-center milling operations. Live tools are mounted in a continuous 360 deg B-axis and powered by a 2 hp spindle motor. Rigid tapping is standard, as is the Kennametal KM-25 quick-change system that minimizes tool change time. A matched Mitsubishi CNC system combines a Mitsubishi M830S control with a 15 in (275 mm) LCD, Mitsubishi servomotors and amplifiers for top reliability and performance. A Fanuc OiT-F, 15 in (275 mm) LCD system, also with matched motors and drives, is available. Standard machine features include a bar feeder interface, parts conveyor and catcher, chip conveyor, collet chucks and a 400 psi coolant pump.

The machine frames and all major components are cast from Meehanite iron. Large, 35 mm Hiwin roller type linear guideways and double-anchored, pre-tensioned 32 mm ball screws maximize rigidity and precision. “These compact, versatile machines enable shops to produce precise, complex parts quickly with the added benefits of the accuracy and consistency that result from processing the parts on a single machine tool,” said Steve Ortner, the president of Absolute Machine Tools. “These machines offer two X/Y/Z tool posts with a full B-axis at an extremely affordable price. Users will win big with this lathe.”
