Frequently Asked Questions
The TJR RC-210R is a roller gear cam rotary table designed for CNC machining applications. It can be installed in either vertical or horizontal positions and is suitable for 4th-axis CNC machining and indexing applications.
The RC-210R uses a roller gear cam drive system. This design uses rolling contact and preload to reduce backlash, improve rigidity, and provide smooth rotary movement during machining.
The RC-210R has a 210 mm table diameter. It also has a 40 mm center through hole, making it suitable for a range of CNC machining and workholding setups.
Yes. The RC-210R is designed as a CNC 4th-axis rotary table for applications that require accurate workpiece rotation and indexing. It can help reduce the need to reposition a workpiece manually during multi-side machining.
The RC-210R has an indexing precision of 30 arc-seconds and a repeatability of 6 arc-seconds. Its minimum increment is 0.001°, making it suitable for precision CNC indexing applications.
The RC-210R has a maximum table rotation speed of 83.3 rpm. The actual operating speed can depend on the CNC machine, motor configuration, workpiece, and machining conditions.
The RC-210R can handle up to 75 kg vertically. With a support table, the allowable vertical workpiece load is 150 kg, while the allowable horizontal workpiece load is also 150 kg.
The RC-210R uses a pneumatic clamping system operating at 0.6 MPa (6 kg/cm²). Its specified clamping torque is 304 N·m, helping hold the workpiece securely during machining.
A roller gear cam rotary table can provide low backlash, high repeatability, smooth movement, high rigidity, and low maintenance. The rolling-contact design also helps reduce wear and transmission losses compared with conventional sliding-contact mechanisms.
The TJR RC-210R CNC rotary table combines a 210 mm table size, roller gear cam transmission, high repeatability, pneumatic clamping, and vertical or horizontal installation. It can be a practical choice for manufacturers looking for a reliable 4th-axis CNC indexing rotary table for precision and production machining.
