The QuickTECH i-42 / i-60 Ultimate bar processing machines provide complete part machining including complex milling functions. The compact, high precision, high production CNC mill/turn centers are cast from rigid Meehanite iron. Available in both 42 mm (1.65″) and 60 mm (2.36″) bar capacities, the i-42/i-60 features 10 axes, 2 turning spindles, 2 milling spindles, 2 B-axes, and a total capacity of 56 tools . A 4 axis (X,Y,Z,B) gang type vertical tool post serves each C-axis spindle.

Turning Spindles

The main spindle has a 15 HP high torque motor. The sub-spindle is equipped with a 7.5 hp high torque integral motor for backworking. The main spindle has a 42mm bar capacity (60mm for i-60) and the sub-spindle has 30mm (1.18″) bar capacity. Both spindles feature a full continuous C-axis with braking system and are both standard with 42mm DIN-173E-42B collet chucks (60mm DIN-185E-60B for i-60). The main and sub-spindle are synchronized for fast and accurate part transfer. Both spindles employ P4 high precision bearings for stability and heavy cutting ability.

Tooling System

A 4-axis gang tooling system consisting of linear X,Y, and Z axes plus a rotary B-axis serves each spindle. The main tool post features 6 O.D. turning tools, 5 I.D. turning tools, and 12 live tools. The sub-tool post features 5 O.D. turning tools, 9 I.D. turning tools, and 12 live tools. The live tools are powered by a 2 HP spindle motor and are mounted in a continuous 360˚ B-axis. Each tool post has a Y-axis for off-center milling operations. Tool change time is near zero. Rigid tapping is standard. In addition, QuickTECH’s standard tooling system is Kennametal KM-25 quick change, and KM-25 bases are supplied with the machine for O.D. turning tools.
