The QuickTECH TT-42 CNC is a high-precision, high-production turning center with milling capability. Available in both 42- and 60-mm bar capacities, it is said to deliver fast, strong and accurate machining in a compact footprint. The machine’s Meehanite, cast iron frame and components provide strength and rigidity. Maximum travel and feed is 5.51" × 16.14" × 9.05" (140 × 410× 230 mm) on the main axis and 16.14" × 16.14" × 14.17" (410 × 410 × 360 mm) on the sub-axis. With complex milling functions, eight axes and four spindles—two for turning, two for milling—the machine enables complete part machining.
A three-axis gang tooling system serves each spindle. Live tooling is available on both the main- and subspindle, with 12 live tools for axial and radial milling, drilling and tapping operations. A total capacity of 31 tools is available for complex machining tasks. The main tool post features six OD turning tools, four ID turning tools, three radial live tool heads, and three axial live tool heads. The sub-tool post features four OD turning tools, five ID turning tools, three axial live tool heads, and three radial live tools heads. Live heads are powered by a 1.3-hp (2-hp option) spindle motor. A flexible tooling system is standard, with quick-change toolholders for easy changing.
Also on display is the QuickTECH IT-42 ROBO, a compact, high-precision, four-axis Swiss-type machine with C-axis live tooling that delivers robotic loading for unmanned chucking operations. The lathe features internal integration of a Mitsubishi six-axis articulated robot loaded with 88 programs. According to the company, the robot requires no additional floor space, and will not hinder the machine operator during setup or while operating the Mitsubishi M700 control system.

Robotic Cell Cuts Cycle Time, Improves Part Quality

Sew-Eurodrive Inc. worked with Okuma America’s authorized systems dealer, Gosiger Automation, to design an automated cell that includes an automatic, magazine bar feeder that loads 6-ft. lengths of barstock into the machine. The shop also switched to an Okuma twin spindle, twin turret turning center so all of the machining operations are completed in one setup, thus eliminating additional fixtures and operator intervention. The resultant system reduces cycle times and requires much less operator involvement. As a result, production time per part was more than cut in half – from about 5 minutes to 2 minutes, 20 seconds.
