What the maker published about the Mazak QTN 350-II

With the QTN 350-II, Mazak spread one 2-axis CNC turning design across three bed lengths: 26 in, 60 in and 80 in. Whatever the bed, swing is limited to 26.77 in and turned diameter to 16.540 in, and the spindle passes bar work of 4.0 in. Only length changes with the bed: machining length is 23.837 in, 60.712 in or 81.087 in, in that order. The main spindle is integral with its motor, holds a chuck of 12 in and is capped at 3300 rpm; over 30 minutes its motor delivers 40.0 hp / 30 kw. There are 12 tool places on the upper turret, and X travel is 10.13 in. Programming on the MATRIX NEXUS control is done in MAZATROL's conversational format or in EIA-ISO. The tailstock answers to CNC programs, tool measurement comes from an automatic tool eye, through-hole chuck packages are listed, and the machine can be fitted with a bar feeder or with robot loading for unattended running.
