What are Rotary Systems


Otherwise referred to as a rotary table, a rotary system is a precision positioning (for work) device that is used in the metalworking industry. One of the main features of this system is that it enables the user or operator to either drill or cut work at exact intervals around either a vertical or horizontal axis. While some of the rotary systems or tables have been designed to allow the use of index plates, some, on the other hand, can be fitted with dividing plates that enable typical work positioning at areas or positions where indexing plates are unavailable.

Generally, rotary tables have been designed with a solid base which helps make provision for clamping down into another table or fixture. One of the main features of these tables is that they have been designed to improve the overall efficiency level of operators to ensure that they are able to cut or drill at exact intervals.

Uses Of Rotary Systems

For improved efficiency, rotary tables have been designed to be mounted “flat” with the tables rotating continuously around a vertical axis. While this is the best way to mount a rotary system, an alternative way to do this is to mount the table right on its end or have it mounted at exactly 90° angle plate. When mounted by the end, the rotary system rotates around the horizontal axis. These rotary systems over the years have been used in these ways;

  •  Rotary systems have been used to precision-machine spanner flats on a bolt.
  • They can be used to drill holes equidistant to one another in a circular flange.
  • They can be used to cut round pieces with protruding tangs
  • These rotary systems can be used to create big diameter holes through milling in circular toolpath as well as on small milling machines that do not have the power to drive large twist drills.
  • These rotary systems can be used to cut or make complex curves with a proper set-up.
  •  These rotary systems can be used to cut or make straight lines at an angle.
  • One of the popular uses cases of these rotary systems is that they can be moved by the user from the center of rotation to anywhere that it is being cut. This goes ahead to enable an arc to be cut at any place or part.

Applications Of Rotary Systems

While we have mentioned some of the many uses of rotary systems, it is best that we mention its application as well. In the last couple of years, these rotary systems have been used in a wide range of applications and in various industries. While most people thought that they could only be used in the metalworking industry, you will find it interesting to know that there are real case applications of these systems in the automation and aerospace industries. In these industries, they are used in the manufacture as well as the inspection of essential elements. Surprisingly, it is used in the film and animation industry. In the film industry, these systems are being used to achieve a higher level of precision and accuracy in photography and filming.
In addition to these applications mentioned, these rotary systems or tables can be used in assembly positioning. In essence, they can be used to achieve a higher precision and accuracy level when it comes to the assembly of vital or essential components in the manufacturing industry.

What To Consider When Choosing A Rotary System

While there are a number of rotary systems to choose from, there are a number of things that you need to take into consideration when it comes to choosing the best system for the task you wish to accomplish. These factors include but are definitely not limited to these;

  • The workable diameter; this simply refers to the surface area of the table or system. A rotary system with a workable diameter would offer a higher level of precision and accuracy than one with a not so workable diameter.
  • The maximum axial load which is simply the amount of load that a rotary system can support when it is pushed. A rotary system with a higher load has proven over the years to be the best.
  • The table rotation speed should also be taken into consideration.
