ETEL recently announced their new generation of indexing tables: the RTMB.
By combining ETEL’s torque motors with HEIDENHAIN’s high-resolution encoder technology in a compact package, the RTMB delivers improved torque density with higher positioning accuracy.
With lower inertia and increased continuous torque, ETEL’s indexing tables are now capable of even higher dynamics and shorter indexing times, resulting in increased machine throughput for the end-user.
In comparison to its predecessor, the RTMB offers 15 percent improved continuous torque, a 20 percent reduction in inertia, 10 percent improved peak torque. It also offers 600VDC compatibility while maintaining the same mechanical (pin-to- pin) interface for easier integration.
It also offers improved in accuracy (±20arcsec), unidirectional repeatability (±2arcsec) and bi-directional repeatability (±3arcsec).
The RTMB family consists of indexing tables with five different active lengths to match torque and size with specific application requirements, providing peak torque up to 197 Nm, continuous torque up to 36.4 Nm, and top speeds of 1200 RPM. All RTMB tables have an optimized 166 mm outer diameter and a large, 25 mm hollow shaft.
Alone or coupled with ETEL’s force controlled short stroke actuators and AccurET controllers, the RTMB can be used for applications including:
- Back-end semiconductor manufacturing
- Electronics
- Automation
- Printing, such as MEMS testers, die bonders, pick and place testers and turret testing handlers.
