Absolute Machine Tools is now the exclusive North American distributor of the Quicktech line of CNC turning centers including the i-42 Ultimate and i-60 Ultimate high-production turning machines. These turning centers from Quicktech enable complete machining, including complex milling operations, of medium-diameter barstock. With two turning spindles, two milling spindles and two B axes, these machines provide a total of 10 axes and capacity for as many as 49 tools. Bar capacity for the 15-hp main spindle is 42 mm for the i-42 model and 60 mm for the i-60, and 30 mm for the 7.5-hp subspindle on both models. Both main and subspindles feature full continuous C axes and are synchronized for fast, accurate part transfer.

A four-axis (linear X, Y and Z axes plus rotating B axes) gang-type vertical tool post serves each spindle. The main toolpost has six OD turning tools, five ID turning tools and 12 live tools. The sub toolpost features five OD turning tools, nine ID turning tools and 12 live tools. Each tool ost has a Y axis for off-center milling operations. Live tools are mounted in a continuous 360-degree B axis and powered by a 2-hp spindle motor. Rigid tapping is standard, as is a Kennametal KM-25 quick-change system said to minimize tool-change time.

A matched Mitsubishi CNC system combines a Mitsubishi M830S control with a 15" (275-mm) LCD, Mitsubishi servomotors and amplifiers for reliability and performance. A FANUC OiT-F, 15" (275-mm) LCD system with matched motors and drives is also 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 ballscrews maximize rigidity and precision.
