Frequently Asked Questions
The TJR RC-170R has a table diameter of 170 mm (Ø170). Its compact size makes it a good choice for smaller vertical machining centers and machines where workspace is limited.
The RC-170R uses a high-efficiency roller gear cam mechanism. Since it works with rolling contact instead of traditional sliding gears, it helps reduce wear and provides high rigidity and smooth operation.
The maximum workpiece load depends on how the rotary table is installed. In a horizontal setup, it can handle up to 150 kg. For vertical installation, the standard load capacity is 75 kg. With an additional support table or tailstock, the load can be increased to 150 kg.
The RC-170R can be paired with several major servo motor brands. It is compatible with FANUC models such as the alpha iF8 and beta iS8 straight-shaft motors without a key. Mitsubishi models, including the HG-54 and 104 series, are also supported.
The RC-170R is designed for zero backlash operation. Its precise preload adjustment and needle-bearing design help maintain accurate positioning over long periods and reduce the backlash problems commonly associated with conventional gear systems.
The rotary table weighs approximately 44 kg without the servo motor. This relatively compact and lightweight design makes it easier to install on standard machine tool tables.
The RC-170R uses a pneumatic clamping system that operates at 0.6 MPa (6 kgf/cm²). It provides a clamping torque of 304 N·m (31 kgf·m), helping keep the rotary table securely locked during heavy cutting operations.
The RC-170R has a 1:36 speed reduction ratio. This ratio provides a good balance between torque and rotational speed, with the table capable of reaching a maximum speed of 83.3 rpm.
Yes. The RC-170R is designed for use as a 4th-axis CNC rotary table and can also be used in 5-axis machining applications. Its compact design makes it suitable for installation on vertical machining centers and for adding multi-axis machining capabilities.
A sudden power loss or system alarm can sometimes cause a small position shift when the machine restarts. To help prevent this and keep the table securely positioned, it is recommended to use the RC-170R with a compatible brake motor system.
