What Are CNC Rotary Tables And How Are They Used?

CNC rotary tables are a key to automated machining. Before getting into the specifics of CNC rotary tables though, a brief discourse in the development and terminology of CNC machining will help from this point forward.

 

CNC is an acronym for Computer Numerical Control. It is the direct descendant of numerical control (NC) technology; think punch cards and magnetic tape. In turn, NC technology was invented to improve upon cam and tracer machine control in use at that time. Cam and tracer machining required construction of a template to trace and that interposed a costly, time-consuming step that had significant potential for human error.

 

Rotary Tables Defined

 

A rotary table is, as its name suggests, a table that rotates very accurately in concentric fashion around its center axis. In the high-accuracy, high-cost category of rotary tables, accuracy can mean radial runout – the amount of deviation from perfectly centered while rotating on the center axis – of 0.00004 of an inch and angular accuracy – degrees of rotation about the center axis – of 0.0002 of an inch. For the purpose of dampening vibration, the body of a rotary table is normally made of one of the “gray” iron grades. The rotating table plate is typically hardened, alloyed steel that is machined and rotary ground.

 

Purpose of CNC Rotary Tables

 

For automated machining, the entire purpose of CNC rotary tables is to provide a fourth axis. In addition to the normal axes of X, Y and Z, a CNC rotary table adds a rotational axis, known as the “W” axis, to increase machine accuracy and reduce costs. For example, using a CNC milling machine alone to make a stop sign-shaped piece would require moving the cutting tool around the piece to cut the vertical and horizontal sides and then cutting the angled sides by moving the cutting tool on a 45 degree angle as it is removing material. This requires eight machining passes. Each operation introduces a cumulative dimensional error for the sides parallel each other. Using a CNC rotary table for the same part means positioning the cutter in X or Y one time while rotating the part in 45 degree increments for each horizontal or vertical pass. Because it is cutting on only one side of the cutter in either X or Y, any machine tolerance error, tool wear and normal tool deflection from the forces of machining are reduce by half.

Basic Information of CNC Rotary Table

A CNC rotary table is a disc-shaped metalworking device used to obtain precise workpiece positioning. It enables a metalworker to cut or drill a workpiece at precise intervals around a vertically or horizontally fixed axis. A rotary table can be both manually or computer numerical controlled. Certain types of rotary tables are designed to be used with indexing plates or dividing plates for specialized operations. A rotary table used together with one of these positioning plates is generally referred to as a dividing or indexing head.

 

The CNC rotary table device typically has a solid base that can be attached to a separate fixture or table using clamps. This device is basically a rotating disc which holds the workpiece in place during cutting or drilling operations. The disc portion of a rotary table can be freely rotated for indexing procedures or turned by an attached control arm known as a worm wheel. Tables used in high precision operations are typically turned by a duplex-type worm wheel to compensate for backlash. Rotary tables used in automated metal working processes are turned by computer numerical controlled machinery.

 

CNC rotary tables are most often used in a flat position with the table’s axis having a vertical orientation. They are sometimes mounted with the axis oriented in a horizontal fashion so that a tailstock can be used to support the free end of the workpiece. When this device is attached to a secondary table, the workpiece can be centered on the rotary table’s axis which is then centered on the cutting tool’s axis. In this configuration, the axes of the rotary table, secondary table, and cutting tool are coaxial to facilitate concentric cutting operations. This configuration also permits the secondary table to be offset for drilling equidistant holes in a workpiece.

 

It is also a necessary component for many different types of machining and milling procedures. This versatile device can be utilized to perform specialized tasks such as machining spanner flats on bolts and drilling holes in flanges. In certain other configurations, a rotary table can also be used cut complex curves, arcs, and round pieces with protruding tangs. Rotary tables are sometimes used to produce a large-diameter hole in a workpiece by cutting in a tight circular path. This device can also use in place of a lathe when it is operated by a stepper motor combined with a computer numerical controlled milling machine and tailstock.

Advantage of Adding A 4th Axis Rotary Table to Milling Machine

To add a 4th axis rotary table to a milling machine in any sort of work setting provides several advantages to machine work. Having another axis to work with gives milling machine users more precision and accuracy without having to change positions of the part being machined.

 

Also, an additional axis would prove to make any milling machine more diverse in the work it is capable of doing; lathe machines introduce the aspect of a rotating part, so a rotary table would add the same benefits provided. A 4th axis rotary table, in general, can provide more precision and ease to a complex design, reducing time and costs for the production of a certain piece.

 

How It Works

 

To clarify, a 4th axis rotary table serves to add a rotating aspect to the desired piece being shaped. Similar to a lathe’s rotating head-stock, the rotary table serves to hold the piece and move at exact intervals of revolutions. Because it can move in precise degrees of motion, users can easily calculate correct positions, just like it can be done with the other three axes of motion on the machine. Once all four axes are used, making grooves or holes in the piece is much easier than without the rotary table, saving time by discarding the task of removing and resetting the piece in another position. Having the ability to move the piece in determined intervals and precision with diverse planes of motion is important for more complex machine work.

 

The Importance of a 4th Axis Rotary Table

 

Just like with the other three axes of motion, the 4th axis rotary tables can be adjusted for specific amounts of distances to accurately tell what position you are at in relation to the dimensions of the piece. Furthermore, the scales used to measure its motion can save time and resources by reducing the amount of mistakes that could result in major delays, such as re-working the piece from the beginning. Since users will easily be able to calculate and set the positions needed for the work done, machining multiple pieces is simpler to accomplish.

 

Examples of Diversity

 

As stated before, the rotary table adds more diversity to the work the milling machine is capable of doing; some work required with a lathe can be done with the additional axis of motion. Machining the part with holes, for example, may require the user to work with a circular pattern with equal distances, which is certainly possible with 360 degree movements. Along with cutting circular patterns easily, arc cuts, grooves, and other complex curves are included with the benefits of a rotary table; cutting out the teeth of gear parts is another way of work possible.

 

The capability of a 4th axis rotary table is only limited by the skill of the user. It is able to provide the extended degree of motion necessary for complex work needed by any skilled machinist. With quality parts, a machinist is capable of intricate pieces of work, and it would be limiting to not have another axis of motion available. It is important to consider the expansion of work choices for machine work, and this addition is a good starting point for such consideration.
