TJR AR-170R Vertical & Horizontal CNC Rotary Table

TJR products are of an exceptional quality and incredible value for money and come with a 1 year warranty to back up the manufacturer’s confidence in their product. CNCROTARY.COM are main agents for the product and can therefore support it fully throughout its lifetime.

This is an ideal design of product for any VMC machine, particularly those with a good working envelope. The usual collision issues only generally appear with the older DC motorised machines where the motors are much longer than the digital counterpart, such as the Bridgeport VMC with SEM motor on the Heidenhain TNC370 controlled devices. This device is ideal for the smaller VMC machine up to and including around 800 in X. Due the carrying capacity, however, if you have a larger VMC and are doing relatively light work you could mount this device on a raiser block and swing larger diameters than its standard design suggests. The TJR model type R can be used in vertical and horizontal applications, the motor is mounted to the right side of the device and therefore can be laid on its back. The TJR model type R is a full contouring 4th axis device. Can be controlled directly from the machine tool control or via a separate programmable box via M signal start.

On this model the motor would be mounted to the right side on this device and leaves the total through hole capability should you want to machine long bar components that need to be mounted through the centre hole of the table. If this device style may be an issue due to width of the unit, such as collision with machine doors with Y axis travel forward, you should look at rear mounted motor versions such as model type AR-B. In selecting a side mount motor version you should consider the Y axis travel of the machine and if there would be any interference between the guard of the rotary table and the doors of the machine, particularly when referencing the machine, as a lot of VMC machines reference with the Y axis travelling to the front of the machine, towards the operator.
