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.

All about Metalworking Devices – ROTARY TABLE

Businesses in the metalworking industry usually invest in high quality tools and materials. This kind of work requires precision and attention to details. This is impossible without using the right machining devices and materials. People working in such business know that equipment plays a huge role in the production. If you are in this line of business, you should understand that productivity is dependent on the use of the right machines. Here are some tips on buying the right tools for metalworking.

 

Buying the Right Machining Devices

 

Quality should be a top concern when buying machining devices. Heavy machinery used in metalworking usually have to go through high levels of heat. This is why they should be durable enough to withstand the pressure of extreme heat. The work also involves dangerous chemicals. This is why it is important to choose the right grade of materials.

 

You should also remember the industry’s standards when choosing supplies and machineries. Following the strict standards of regulators helps ensure the quality of your products and improves your reputation in the field. Most consumers choose reputable suppliers who commit to the industry standards. They are more confident to do so because they will get products that have passed through several screenings and quality control measures.

 

You can find many companies specializing in supplies for metalworking businesses. You have to make sure, however, that you are making a deal with the right supplier. You need to know whether they are a licensed distributor. Working with appropriately registered companies gives you the right protection from the law whenever problems arise regarding the purchase.

 

ROTARY TABLE – Most Important Devices in a Metalworking Business

 

Other than the quality of products and your supplier’s reputation, you should also keep the unique requirements of your business in mind. Precision is one thing that takes priority in this line of business. This means you should invest in quality precision devices. This is where you should think about finding a dealer of rotary tables. This type of device makes it possible for a metalworker to drill and cut the material on fixed axes and specific intervals.

 

Rotary tables come in different types such as the direct drive high speed rotary table. Some of them allow the metalworker to use indexing plates, while some make it possible to fit dividing tables. A rotary table is one thing metal working businesses cannot go without. Other than for the purpose of drilling holes, these tables are also useful in machining spanner flats on bolts and cutting round pieces with protruding tangs. Mixing helixes and cutting complex curves are also much easier with the help of rotary tables.

 

Rotary tables have different parts with different functions. The most important component is the work table. It consists of a spherical working area where four t-slots are used with clamps. These are used in mounting work pieces.

 

Now that you know the importance and uses of rotary tables, you should start looking for reputable suppliers of such devices.

Tips for Buying Rotary Tables

Rotary table is used in the precision metalworking industry. It is made of a solid base that can be clamped on to the other fixture. In simple words, rotary tables are discs, which rotate freely or by using a worm (hand crank).

 

Rotary indexers are used in different applications like machining, assembly and automation. Other than this, these tables find usage in assembly and equipment positioning. When you are buying a rotary indexer, there are a few things to consider. These include:

 

Diameter of Rotation Dial

The worktable diameter is the surface area of the rotary indexer.

 

Measurement of Through-Hole Diameter

It is the diameter of the breadth of the hole present at the center of the workstation.

 

Maximum Radial Load

When the load is pushed against the rotating plate, the heaviest amount it can support on vertical or horizontal axis is the maximum radial load.

 

Maximum Axial Load of Rotary actuator

Maximum weight the actuators are able to bear at the time of concentric operations.

 

Actuator Speed

Maximum rotation speed set by the manufacturer.

 

Minimum Indexing Increment

Smallest angle setting on the table.

 

Rotary tables can be mounted in horizontal, inverted or vertical styles. When the table is mounted horizontally, it is in a flat, horizontal and upright position. In vertical mounting, surface of the table runs up and down. When it is inverted, the table is upside down in a horizontal angle.

 

The location of drive on rotary table depends on the mount. You can place the drives below, behind, on the top or on the side of the table. When the drive is mounted horizontally, it is located above the surface of the table. When the table is mounted horizontally, the side-mounted drive is placed to the side of the surface of the table.

 

The rotary table can be driven manually, pneumatically, hydraulically and electrically. If you are driving manually, the table should be loosened and it must be turned manually with the crank.

About Rotary Tables

Rotary Table provides rotational force to a drill string for carrying out the process of drilling a borehole. These tables find heavy usage in the metalworking industry. A table is made of solid base that is clamped to a fixture.

In simpler words, rotary indexers are kind of discs that freely rotate or are rotated by using a hand crank (worm). You can mount these tables in vertical, horizontal or even inverted styles. When the table is fixed horizontally, it is in a horizontal, upright and flat position. In case of vertical mounting, the surface of table runs up or down; while, in horizontal angle, it is upside down.

Rotary tables are used in applications like assembling, machining and automation. These tables are also used in equipment positioning. While buying a rotary table, there are a few things to be considered:

Worktable Diameter

A worktable diameter is the surface area of the rotary actuators.

Through-Hole Diameter

The breadth of the hole at the center of the workstation is its through-hole diameter.

Radial Load

Always pay attention to the maximum load the table will be able to bear during concentric operation.

Speed

Check out the maximum rotation speed of the device.

Indexing Increment

It is the smallest angle set on the table.

The mount of the rotary table decides the location of the drive on it. User can place the drive behind, below, on top and even on the side of the table. When you mount the drive horizontally, it’s located over the surface. In case the table is horizontally mounted, a side-mounted drive is place on the side of the surface.

You can drive the rotary tables pneumatically, electrically, manually and even electrically. In case it is being driven manually, make sure the table is loosened and turned manually with crank.
