What Is A Direct Drive Rotary Table (DVR)?

Among other benefits of the Direct Drive Rotary Table, the ability to reference precise data at any moment in time can relate to their superior repeatability, the long time of average operation, their relative free-range of operation, their high tolerability of high and low axial and radial torques during operation, and their ability to provide for the development of new methods of operation. All these benefits are further accentuated by the fact that a Direct Drive Rotary Table is virtually maintenance-free, with only a few necessary maintenance items needed to keep it up and running. Another advantage of a Direct Drive Rotary Table is that they can be used for precision work, making them a great value in the construction field. They have been used for years in the oil and gas, aerospace, and automotive industries, which makes them an industry standard in the industry.

A direct drive rotary table or DVR is a type of table used in the motion measurement industry to measure and control the rotational speeds and temperatures of surfaces. These tables come in many forms, with some of them featuring models intended for high-speed operation. Although they can do the job just as well as high-speed speed measuring equipment, there are some key differences between them that will help you make an informed decision regarding your needs.

The biggest difference between high-speed versions of direct drive rotary tables and high accuracy versions is that a high-speed unit needs a motor with more torque. That means the motor needs to work harder, increasing the possibility of wear and/or damage to the drive system. Because of this, high torque models generally require more maintenance, higher operating temperatures, and may need to be serviced more frequently. Conversely, high accuracy models do not have this problem because they do not need to use as much power. In fact, their motors don’t require any power at all. They can therefore run with no maintenance, no temperature issue, and virtually no damage.

The next difference is found in the shape of the face of the DVR rotary tables. High-speed versions have flat faces while high accuracy models have slanted, rectangular faces. This is again because high torque models need a high face gear to achieve the desired speed. It’s the nature of such a gear that allows them to operate at higher speeds, thus maintaining the slanted surface of high-speed face gears.

The final major difference between high torque and high accuracy DVR rotary tables is the method by which the information is stored. High precision units are generally more durable, but are also more accurate in regards to the measurement of rotational speeds and angular momentum. High speed versions also have chips that store data for different applications. This allows the DVR to operate with one application in mind and then transfer that information to another application. The result is that high torque units can transfer information from one application to another with much less difficulty than high speed units would.

These differences allow for different types of direct drive rotary table to be used in many different applications. For instance, an DVR can work very well for controlling a CNC milling machine. However, the type of CNC milling machine and the tools it works with would also limit the type of CNC rotary table that would be appropriate. That being said, both high speed and precision units can be used on CNC machines.
