Torque Motor Rotary Table Enables Dynamic Machining

Hiwin Corp., a manufacturer in motion control and system technology, highlights its families of precision motion control components with a focus on its Torque Motor Rotary Tables (TMRT).

Designed for machine tool OEM’s and retrofitters, the TMRT series enables three-axis machine tools to be readily upgraded to 3+1, 3+2, 4+1 or even five-axis capability. High speed, high-torque, built-in high-rigidity high-precision bearings, absolute encoders and a powerful brake system promote acceleration capabilities and high-precision when machining complex part geometries.

Hiwin’s TMRT series rotary tables incorporate direct-drive torque motors.  This design eliminates any gear reducers, resulting in the highest dynamic performance and multi-axis path accuracy, Hiwin says. Directly coupled encoders and zero backlash intend to enable tighter part tolerance. Direct drives are designed provide smooth motion, resulting in improved part surface finish. 

The TMRT series incorporates integral liquid cooling in the table, promoting thermal stability even during high-duty cycle, high-load conditions, which yields consistent part quality, Hiwin says.

Also, the TMRT series is compatible with most major CNC brands, making control integration straightforward.

Hiwin Torque Motor Rotary Tables utilize Hiwin’s torque motor components, which are also available for engineers who prefer to design and build a unique table.
