What Are Direct Drive Rotary Tablets?
Rotary-table is an industry term that is used for a specific type of table, Rotary-table can be either a direct drive or a tilting rotary table. Direct drive Rotary Table has the motor very firmly built-in to the table faceplate and the rotary axes are driven by the shaft from the motor directly past the table cam. The tilting table is basically a scaled-down version of the direct-drive table. The tilting tables give extremely high compression and deceleration speeds with equally high acceleration.
Direct drive Rotary Table is considering the most compact and lightweight Rotary Table and is found to be preferred by many over tilting and roller tables due to its excellent balance. They also offer high torque and high speed capability. However these types of tables are known to give poor torque capacity when at rest which results in slower work speeds at lower acceleration. Further more at higher speeds torques become equalized between the drives and the tilt deflectors reducing the overall torque delivered.
The advantage of using a direct drive rotary table is that there is no need for any mechanical and tools to be attached to it. There is also no additional weight as the motor and shaft remains fixed with the table. The only requirement is a stationary power supply to supply the electrical energy and to control the RPMs. The electrical power supply also enables the user to regulate the cooling fan speeds and allows the cooling chamber to be easily maintained. Many users prefer direct drive rotary tables because of their high torque performance and ability to work in any environment.
The main advantages of a rotary indirect drive rotary table are its compact size and light weight. This makes it easier to use than any other design. It also has the ability to provide variable torques which can be altered without changing the length of the shaft or changing the length of the wheel. A typical direct drive rotary table has an indexing system that can be manually set by the user depending upon the required torque. This feature has made it very popular because it is easy to change the torques according to requirements. In addition it is allowed static control, which means that it will remain at the pre-set value irrespective of the changing conditions.
Another important feature of the rotary indexing system is that it can work with any type of drive system. It is therefore possible for even a zero turn CNC router based machines to use them. Many companies that offer and manufacture CNC routers often add a rotary indexing system to the package. This gives all users the ability to use CNC machinery without the hassle associated with traditional CNC lathes. Because of the ease and wide range of applications of the rotary tables, they are being used worldwide in a multitude of different industries.
In summary, direct drive CNC rotary tables are used in applications where high precision and high performance are required. They are used in CNC mills, as well as many other applications where speed and precision are required. Their usability in all types of applications makes them some of the most popular CNC milling equipment on the market. The wide variety of applications and their relative ease of use make them a prime choice among users.
