Quicktech i-42 Twin

The Quicktech i-42 Twin is a gang-tooling bar lathe with a main spindle, a sub-spindle and one shared tool system. It takes 42 mm (1.7 in) bar, or 65 mm (2.6 in) as an option, and turns up to 300 mm (11.8 in) long on the main spindle. That is the longest turning length in the i-42 line; the i-42 Ultimate lists 230 mm (9.1 in).

Here the sub-spindle is a pick-off and back-working unit, not a second machining station with its own cross slide. The table shows a Z2 travel of 390 mm and no X2 or Y2 figure, so the sub-spindle moves along the bed to take the part and then presents it to fixed back-working tools. It handles 30 mm (1.2 in) bar and 150 mm (5.9 in) of turning length on a 3.7 kW (5.0 hp) servo spindle.

The main tool system travels 150 / 415 / 300 mm (5.9 / 16.3 / 11.8 in) in X1/Y1/Z1. Quicktech says the flexible tooling system comes with 9 standard external tools, 9 internal tools and 12 live tools, and puts the total at 30 tools. The 12 motorized tools sit on a tilting milling head that the maker describes as rotating through 360°; the page also shows the machine without the B axis, so check which head is quoted.

Main spindle power is 11.0 kW (14.8 hp), fitted as standard on this model. Guideways are 35mm HIWIN linear rails. The control is a Mitsubishi M80, a 25 bar pump backs up the 5 bar coolant pump, and the machine weighs 5,300 kg (11,684 lb).
