Frequently Asked Questions
The FHR-255-2W-RC320 features a Ø255 mm rotary table and is designed for vertical and horizontal applications. It uses an add-on installation mode and belongs to TJR’s Multi Spindle Coupled Series, making it suitable for coupled multi-spindle 4th- and 5th-axis CNC machining.
The rotary axis provides 360° rotation, while the tilting axis offers a wide -110° to +110° range. This allows the coupled rotary tables to position workpieces at multiple angles for complex multi-axis machining operations.
The rotary axis uses a Worm & Worm Gear transmission mechanism, while the tilting axis uses a Roller Cam transmission mechanism. The rotary axis has a 1:150 reduction ratio, while the tilting axis uses a 1:90 reduction ratio, providing controlled and precise axis movement.
The FHR-255-2W-RC320 provides a minimum programmable increment of 0.001°. The rotary axis has 40 arc-seconds indexing precision and 6 arc-seconds repeatability, while the tilting axis provides 60 arc-seconds indexing precision and 8 arc-seconds repeatability.
Both the rotary and tilting axes use hydraulic clamping rated at 3.5 MPa / 35 kg/cm². The rotary-axis clamping torque is 687 kgf·m / 70 kgf·m, while the tilting-axis clamping torque is 1,717 kgf·m / 175 kgf·m, providing strong holding force during machining.
The FHR-255-2W-RC320 can be configured with major CNC servo motor systems including FANUC, Mitsubishi, Yaskawa, Siemens, Heidenhain, and Syntec. TJR specifically lists FANUC αiS12 / βis12 for the rotary axis and αiS12 / βis12 for the tilt axis. Mitsubishi models include HG-154 for rotary and HG-204 / HG-354 for tilt. TJR also lists Siemens 1FK7063 for rotary and 1FK7083 for tilt.
Both the rotary and tilting axes have a maximum table speed of 16.6 rpm. These speeds provide controlled movement for indexing and coordinated multi-axis machining applications.
The FHR-255-2W-RC320 supports a maximum workpiece load of 100 kg per plate at 0° horizontal and 75 kg per plate when tilted from 0° to 90°. Its allowable horizontal inertia load capacity is 0.8 kg·m².
With rotary-table clamping, the FHR-255-2W-RC320 has an allowable thrust load of 14,715 N / 1,500 kgf. Its specified axial moment is 1,717 N·m / 175 kgf·m, radial moment is 687 N·m / 70 kgf·m, and driving torque is 540 N·m / 55 kgf·m.
The FHR-255-2W-RC320 features an Ø80H7 mandrel sleeve, Ø80 mm center through hole, and 325 mm horizontal table height. It uses a 12H7 T-slot and 18h7 guide block. The unit has a net weight of 740 kg excluding the servo motors.
