TJR Worm Gear Dual Arm Tilting Rotary Table - FHR Ø400

The TJR FHR-400C-540-HR400B has a table diameter of 400 mm (Ø400). Its large dual-arm construction provides a rigid workholding platform for heavy-duty CNC machining and demanding 4th- and 5th-axis applications.

The FHR-400C-540-HR400B uses a worm and worm gear transmission mechanism on both the rotary and tilt axes. This proven transmission design provides strong load resistance, reliable operation, and controlled movement for demanding multi-axis CNC machining applications.

The rotary axis provides a full 360° rotation, while the tilting axis has a range of -110° to +110°. This wide tilting range allows the FHR-400C-540-HR400B to access multiple workpiece surfaces and complex machining angles for 5-axis CNC applications.

The rotary axis has an indexing accuracy of 15 arc-seconds with 6 arc-seconds repeatability. The tilt axis provides 60 arc-seconds of indexing accuracy and 8 arc-seconds of repeatability. Its minimum incremental angle is 0.001°, supporting precise positioning during multi-axis machining.

The FHR-400C-540-HR400B uses hydraulic clamping on both the rotary and tilt axes at 3.5 MPa (35 kg/cm²). The rotary axis provides a clamping torque of 1,128 kgf·m, while the tilt axis provides 2,698 kgf·m, delivering strong holding force for demanding cutting operations.

The FHR-400C-540-HR400B can support a maximum workpiece load of 220 kg when the rotary axis is positioned horizontally at 0°. When the rotary axis is tilted between 0° and 90°, the allowable workpiece load is 120 kg. Its allowable horizontal inertia load capacity is 4.4 kg·m².

Both the rotary and tilt axes use a 1:120 speed reduction ratio. The rotary axis has a maximum table rotation rate of 25 rpm, while the tilt axis has a maximum rotation rate of 16.6 rpm. These high reduction ratios provide controlled movement and high torque for heavy-duty multi-axis machining.

The FHR-400C-540-HR400B can be configured with major CNC servo motor systems including FANUC, Mitsubishi, Yaskawa, Siemens, Heidenhain, and Syntec. TJR's published specifications list FANUC αiS12 / βiS12 motors for the rotary axis and αiF22 / βiS22 motors for the tilt axis. Mitsubishi options include HG-154 for the rotary axis and HG-354 for the tilt axis.

The FHR-400C-540-HR400B has a Ø120 mm center through hole, with an Ø120H7 inner diameter for the mandrel sleeve. The table also features a 14H7 T-slot and an 18h7 guide-block width for accurate installation and workholding.

Yes. The FHR-400C-540-HR400B is a dual-arm tilting rotary table designed for both vertical and horizontal installation. Its 360° rotary axis and -110° to +110° tilting axis provide two-axis movement, making it suitable for 4th- and 5th-axis CNC machining, multi-sided machining, and complex-angle operations.

The FHR-401C-820-HR400B features a Ø400 mm rotary table. It is designed for both vertical and horizontal applications and uses an add-on installation configuration, making it suitable for integration with CNC machining centers for 4th- and 5th-axis machining.

The rotary axis provides 360° continuous rotation, while the tilting axis provides a wide -110° to +110° tilting range. This enables multi-angle machining and access to complex surfaces that are difficult to reach with conventional 3-axis machining.

Both the rotary and tilting axes use a Worm & Worm Gear transmission mechanism. The design provides controlled high-rigidity motion for demanding 4th- and 5th-axis machining applications. Both axes use a 1:120 speed reduction ratio.

The minimum programmable increment is 0.001°. The rotary axis has an indexing accuracy of 15 arc-seconds and repeatability of 6 arc-seconds, while the tilting axis provides 60 arc-seconds indexing accuracy and 8 arc-seconds repeatability.

Both the rotary and tilting axes use a hydraulic clamping system rated at 3.5 MPa / 35 kg/cm². The rotary-axis clamping torque is 1128 kgf·m (115 kgf·m equivalent specification), while the tilting-axis clamping torque is 2698 kgf·m (275 kgf·m) as specified by TJR.

The FHR-401C-820-HR400B can be configured with major CNC servo motor systems including FANUC, Mitsubishi, Yaskawa, Siemens, Heidenhain, and Syntec. TJR's published specifications list FANUC αiS12 / βis12 for the rotary axis and FANUC αiF22 / βis22 for the tilt axis. The listed Mitsubishi models are HG-154 for rotary and HG-354 for tilt.

The rotary axis has a maximum table speed of 25 rpm, while the tilting axis can reach 16.6 rpm. Actual operating speed can vary according to the selected servo motor and machining conditions.

The rotary table supports a maximum workpiece load of 220 kg when horizontal at 0° and 120 kg when tilted between 0° and 90°. Its allowable horizontal inertia load capacity is 4.4 kg·m².

The table has an allowable thrust load of 17,658 N / 1,800 kgf with rotary-table clamping. The specified axial moment is 2,698 N·m / 275 kgf·m, radial moment is 1,128 N·m / 115 kgf·m, and driving torque is 785 N·m / 80 kgf·m. These specifications make the unit suitable for heavy-duty multi-axis machining applications.

The FHR-401C-820-HR400B has a Ø120H7 mandrel sleeve, Ø105 mm center through hole, and 380 mm horizontal table height. It uses a 14H7 T-slot and 18h7 guide block. These dimensions provide a rigid mounting platform for fixtures and workpieces in CNC 4th- and 5th-axis applications.
