The patented Royal Rota-Rack® is an automatic accumulator that can be used with any bar-fed CNC lathe to safely collect finished parts, providing hours of highly profitable, unmanned production.
User enters the part cycle time and degree of turntable rotation via a simple PLC controller. A counter can also be set to shut the Rota-Rack® down after a specified number of parts have been collected.
As a finished part comes out of the lathe, it drops onto the conveyor and is moved towards the Rota-Rack’s® rotating turntable.
Each time a part comes out of the machine, the Rota-Rack® indexes to the next position. The degree of turntable rotation is easily adjusted according to part length.
As the turntable indexes, the parts are gently guided towards the center via the spiral.
After several hours of unmanned production, finished parts are manually removed from the center of the Rota-Rack®.
Adding a Royal Rota-Rack® to a bar-fed CNC lathe greatly increases machine utilization and throughput.
The Royal Rota-Rack® has been designed to provide maximum part protection, a feature that is important for all parts but one that is especially useful for parts with delicate external features like threads, edges, and corners.

Large Enough to Hold Lots of Parts, Small Enough to Fit Almost Anywhere
The diameter of the Rota-Rack’s® turntable is 36", making it large enough to hold a significant number of parts, yet small enough to fit into tight spaces. The Econo-Rack™, our light-duty parts collector, is even more space-efficient at 28". When considering space utilization, it is very important to note that the Rota-Rack® can double or triple capacity, yet its footprint is only about 10% that of a new lathe and bar feeder.

We often refer to the Rota-Rack® as "Off the Shelf Automation" because it is such a breeze to install. In fact, most users report having it up and running within an hour of unpacking it from its shipping crate.
Each Rota-Rack® normally ships with its height and orientation preconfigured according to customer specifications. And because the unit does not need to connect to the lathe either physically or electrically, installation is simply a matter of attaching the legs, sliding it into place in front of the machine, and plugging it into a standard 110v outlet.
The one additional step that may be required for some installations is the modification of the lathe’s part collection box, usually located on the door of the machine. In order for parts to reach the Rota-Rack® or its conveyor, the bottom and side of the box may have to be opened up as shown in the photo.
