Mill/Turn Centers Feature Integrated 6-Axis Robot for Fast Loading/Unloading of Bar Stock

Quicktech i-42 ROBO and i-60 ROBO 4-axis mill/turn centers feature integrated 6-axis Mitsubishi robots for fast, automated loading and unloading of medium-diameter (i42: 42mm/1.68", i60: 60mm/2.36") bar stock. In addition to carrying out highly productive turning, the machines can perform complex milling with standard live tools. An optional 360° B-axis further extends milling capabilities. Quicktech machines are distributed in North America exclusively by Absolute Machine Tools, Inc.

The Mitsubishi S-series 6-axis high-speed robot automatically loads, unloads, or turns over parts weighing up to 13 lbs. An optional multi-tray pallet handling system enables untended operation. The robot is contained within the machine and is positioned to allow unimpeded operator access for machine setup and operation.

The i-42 ROBO and i-60 ROBO machines operate in 4 axes (5 with the optional B-axis), with a 15-hp high-torque turning spindle that features C-axis capability, a 2-hp live tool milling spindle, and capacity for 17 tools (23 with B-axis). A standard DIN-173-42B collet chuck provides capacity for 42mm bar, while an optional with a 60mm collet or 6", 3-jaw chuck offers 60mm bar capacity.

The machines' innovative tooling arrangement provides partmaking flexibility and efficiency. A 3-axis (4-axis with optional B-axis) gang-type vertical tool post serves the main spindle with 6 O.D. turning tools, 5 I.D. turning tools, and 3 radial and 3 axial live tool heads. The tool post also provides Y-axis motion for off-center milling operations. Rigid tapping is standard, as is the Kennametal KM-25 quick-change system that minimizes tool change time.

A matched CNC system combines a Mitsubishi M80A control, featuring a 260mm (10.4") LCD, with Mitsubishi servomotors and amplifiers for top reliability and performance. Standard machine features include a bar feeder interface, parts conveyor and catcher, chip conveyor, collet chucks and a 400 psi coolant pump.

Machine frames and all major components are heavy Meehanite cast iron. In addition, the i42 and i60 ROBO machines utilize large 35mm Hiwin roller type linear guideways and double-anchored, pre-tensioned 32mm ballscrews.
