The Megaturn Nexus 900 is a new generation CNC vertical turning center that is suited for heavy-duty cutting of large cast iron and steel workpieces found in the construction machinery, industrial machinery and jet engine industries.
The turning center features a maximum workpiece size measuring 36.2" × 31.5" and uses roller guides on the X and Z axes to ensure high rigidity and smooth cutting at high speed feed rates.
It is equipped with a 40-hp, 1,250-rpm, integrated-motor, main turning spindle that generates 2,696 foot-pounds. The machine carries a maximum load capacity of 6,614 lbs, including the chuck.
The machine is designed with a 12-position drum turret for rapid tool indexing. The turret is clamped by 16.7 tons of force on a 12.99" high-index coupling, enabling high-performance machining and intermittent cutting. The machine also removes material at a rate of 58.6 in3/min, which is 1.4 times higher than comparable vertical turning lathes, the company says.
Another standard device is the Tool Eye, an automatic tool-presetting system. By bringing the tool tip into contact with the Tool Eye, offset of tool nose position, tool measurement and data registration are done automatically, ensuring accuracy and reducing setup time. The center is equipped with the company’s sixth-generation CNC system, Mazatrol Matrix Nexus, for advanced conversational programming and EIA input.
Robot-Fed Multitasking Lathe with Conveyor
This machine can run for a long time without any operator intervention, and users can machine finished parts from slug stock or cast blanks while achieving the same high productivity as if they were machining from barstock, the company says.
