The rotating axis of the MTHR rotary table can be intergraded into a CNC machine control as a full 4th axis or it can be operated as an indexer by utilizing TJR’s SAC (Single Axis Controller). The MTHR unit is manufactured with a large radial-axial preloaded bearing system for high rigidity that can perform light or heavy cutting.
The MTHR is TJR’s 1 degree manual tilt rotary table offering that employs a hydraulic brake system. This manual tilt rotary table is an affordable solution for customers who require an automated rotating axis but also occasionally require the ability of a tilting axis.
The MTHR unit uses a dual lead worm shaft and worm gear to ensure long term indexing accuracy in both directions. In addition the MTHR has a powerful double disk braking system for the tilting axis.
