What Are Direct Drive Rotary Tables?
Direct Drive Rotary Table, also known as the DDS, is a type of rotary table that is used to the constant operation that is often more accurate and rapid than traditional rack and pinion or other face gears. Direct Drive rotary is an effective solution for use in precision manufacturing.
There are two most common types of DDS – centrifugal and axial. Centrifugal has one or both axes mounted on a stationary shaft. Axial rotary is a more conventional style that has a single shaft and a variety of axis. Centrifugal and axial models can be either motorized or un-motorized. Motorized models have a motor mounted to one or both sides of the table and typically have multiple speed settings.
A DDS is made up of a rotating shaft with a counterbalance. The weight of the counterbalance ensures that the shaft will stay in its initial position. When a ball enters the DDS, a spring pushes it into place. As the ball moves around the table, the shaft spins, keeping the ball in its original position. This is how DDSes work. It does not make use of any gear in its operation.
Many manufacturers use DDS for many different types of applications. They are commonly used in machining applications because of their accuracy. A DDS can accurately machinate materials at high speeds. The DDS is also used for lathe operation and table top applications such as in manufacturing tables, lathes, and grinders. A DDS is also commonly used in automotive and truck applications for its accuracy and fast turning capabilities. These models are also used in some electronic applications, including in digital imaging processors and digital camera.
The DDS is also known as the Diamond, which is the name of its rotating diamond plate. The Diamond plate acts like a rotating blade so when the ball is hit in the middle of the diamond plate, a rotational motion is generated. This rotational motion is then transmitted to the shaft of the DDS.
DDS are commonly used in aerospace applications, especially for machining purposes. In some cases they are also used in aerospace applications and in the military for cutting and drilling applications. As the name implies, a DDS is used in a variety of applications for a number of applications.
There are many variations of this type of table that include table mounted, free standing, and fixed and variable-pitch shafts. Table mounted versions of the DDS have a fixed shaft at the center of the table and the height of the shaft depends on the diameter of the DDS and the table thickness. Free standing DDSs are table mounted without a fixed shaft and instead the distance between the two ends of the DDS is adjustable so the height of the shaft can be varied.
Fixed and variable-pitch DDSs have a fixed shaft that has a pitch that changes along with the angle of the shaft. with the height being equal to the table thickness.
