How a Rotary Table Operates
How a Rotary Table Operates
A rotary table is basically a precision machining tool used primarily in the metalworking industry. It allows the operator to cut or drill work within a given area around an adjustable axis. This type of machine has many advantages over other types of milling machines, including CNC mills which are used for CNC machine welding and sheet metal cutting. Rotary tables are also used for drilling, counterboring, turning, grinding and engraving.
The most common use for rotary tables is in the production of vertical shaft grinders and press brakes. The use of rotary tables has increased over the years because they provide users with accurate machining operation that is difficult to achieve with the use of other milling machines. CNC mills are commonly used for intricate designs of metals as well as for simple processes such as sanding, honing and polishing. This equipment is often used by professional metalworkers, as well as for a variety of other applications due to their accuracy and ease of use.
There are two types of rotary tables that can be used to perform different tasks. The first axis of the machine is usually set up in a horizontal plane and provides operation in a straight line. The other axis of the table rotates in a circular orbit around the work piece and provides a more precise, intricate motion. The benefits of using this type of machine are that it provides more accurate precision as it has more movement than straight line operations and it requires fewer movements to make one cut.
Using a rotary table to perform drilling operations can be accomplished in a variety of ways. One method involves the use of a rotary lever. This is attached to either the work area or the table itself and allows the user to control the amount of drilling that occurs. A different method uses a drilling rig. A drilling rig is similar to a handheld device with a drill bit fixed to the end and a collar on which the bit fits.
The accuracy of a rotary table can be increased by adjusting its level of linearity. This is done by lowering the appropriate drive force and raising the appropriate Torque. Increasing the torque setting will result in a higher level of accuracy as the machine rotates more rapidly over a smaller size. High accuracy can be achieved if the level of precision desired is not very high; otherwise, the accuracy of the bit will not change much.
The most common way that a rotary table is used is to cut a workpiece in a simple fashion. It may be a small plastic part that needs to be cut, such as a threaded component. The operation begins by aligning the workpiece in the cutting direction with the axis of the table. Then it is moved into the higher rotation range and the workpiece is slid down the axis. Once the workpiece has been moved down the axis, it is turned once more and the cutting operation begins. In this example, the workpiece is being rotated in place relative to the stationary axis, so the measurement of torque from the machine can be determined relative to the center of the workpiece.
