5c collet rotary table free sample

The AR-5c is TJR’s pneumatic collet rotary table that employs a pneumatic brake and 5c collet closer system. This unit is an affordable solution for customers who require a 5c collet for their workpiece as an alternative to a 3 or 4 jaw chuck.

The AR-5c collet rotary table can be integrated into a CNC machine control as a full 4th axis or it can be operated as an indexer by utilizing TJR’s SAC (Single Axis Controller).  In addition this series is offered in Right Handed and Left Handed motor mount configurations with a powerful pneumatic braking system.

The AR-5c unit is manufactured with a radial-axial preloaded bearing system for high rigidity that can perform light or heavy cutting. The AR-Series uses a dual lead worm shaft and worm gear to ensure long term indexing accuracy in both directions.

When the Servo Control executes a G94, a 250 millisecond delay is required before starting the next step. This may cause the mill axis to move before the table rotates, leaving a flat spot in the cut. If this is a problem, add a 0 to 250 milliseconds dwell (G04) after the M-Code in the mill program to prevent mill axis movement.

By adding a dwell, the rotary unit and the mill start moving at the same time. It may be necessary to alter the feed rate on the mill to avoid timing issues at the end of the spiral. Do not adjust the feed rate on the rotary control; use the mill with its finer feed rate adjustment. If the undercut appears to be in the X-Axis direction, increase the mill feed rate by 0.1. If the undercut appears in the radial direction, decrease the mill feed rate.

If timing is off by several seconds, such that the mill completes its movement before the rotary and there are several spiral moves one after another (as in retracing a spiral cut), the mill may stop. The reason is the mill sends a cycle start signal (for next cut) to the rotary control before it has completed its first move, but the rotary control does not accept another start command until it finishes the first.
