Grob Systems, Inc., a global leader in the development of manufacturing systems and machine tools, has announced it will be highlighting power skiving applications on its G550T Mill/ Turn Universal Machining Center at Southtec Booth #829 located at the Greenville Convention Center in Greenville, SC, from October 24–26, 2023. The G550T is part of the Grob 5-Axis Turning Centers Line, capable of machining a part by milling and turning in a single setup, saving time, costs and floor space.
Southtec attendees will see live continuous machining Power Skiving demonstrations on the G550T. The Grob-cycle power skiving NC user-cycle produces spur and helical internal and external gears at defined angles. Demonstrations will show how having the right machine, tools, software and feeds/ speeds maximizes productivity by producing precise gears, faster in one operation for challenging applications, including EV. Power skiving is up to 10x faster when compared with shaping (internal gears), and up to 4x faster vs. hobbing (external gears).
The G550T Mill/ Turn 5-Axis Machining Center offers optimized milling and turning performance for a broad range of part materials, and is equipped with a Siemens 840D SL control, 14,500 rpm spindle, and an HSK-T100 tool interface. For maximum stability and machining performance, the G550T features a powerful mill-turn table with t-slots arranged in a star shape. Three linear and two rotary axes permit 5-sided machining, as well as 5-axis simultaneous interpolation, with a swivel range of 230 degrees in the A-axis and 360 degrees in the B-axis. The drive design is based on two symmetrically located ball screws and weight compensation in the Y-axis, and wear-free torque motors in the A and B axes.
The G550T's unique machine concept includes a horizontal spindle position that permits the longest possible Z-travel path and optimum chip fall. The arrangement of three linear axes offers maximum stability by minimizing the distance between the guides and the machining point (TCP). The G550's tunnel concept allows the largest possible component to be swiveled and machined within the work area without collision - even with extremely long tools.
The Grob 550T is also ideally designed for automated solutions. Grob's automation technology ranges from pallet and part handling/ storage systems to highly flexible, turnkey manufacturing lines. Attendees can discuss the configuration that optimally suits their needs.
