Frequently Asked Questions

The AR-250R is a worm gear rotary table made for CNC machines. It has a 250 mm table diameter and is used for accurate workpiece positioning.

The AR-250R is used for milling, drilling, indexing, and other CNC machining jobs. It helps rotate the workpiece to the right position.

Yes. The AR-250R can be installed in both vertical and horizontal positions, depending on the CNC machine and the type of work.

The rotary table has a diameter of 250 mm. It also has a 40 mm center hole and a 40H7 mandrel sleeve.

The AR-250R has an indexing accuracy of 20 seconds and a repeatability of 6 seconds. It can make movements as small as 0.001°.

The AR-250R uses a worm gear drive with a 1:90 reduction ratio. This helps the table move smoothly and position the workpiece accurately.

The maximum rotation speed is 44.4 rpm. The actual speed may depend on the servo motor and machining conditions.

The AR-250R can hold up to 75 kg when used vertically. With a support table, it can handle up to 150 kg. The horizontal load capacity is also 150 kg.

Yes. The AR-250R uses pneumatic clamping at 0.6 MPa. The maximum clamping torque is 304 N·m.

The AR-250R can be fitted with FANUC or Mitsubishi servo motors. The available options include FANUC αiF8 and βis8 and Mitsubishi HG-54 and HG-104. The right option depends on the CNC machine.
