The high precision rotary table is also a type of the rotary table. The function of the high precision rotary table is also to rotate the work piece so the cutting tool can create the contour we desired out of the work piece.
The art of cutting and shaping is truly limitless. These days, we can see so many statues or sculptures situated in the park. All of these statues and the sculptures are months and sometimes years of hard work for the artist. The artist expressed their inspiration through the crafting of these masterpieces. Several materials can be used to make the statues and the sculptures. The metals are ductile and malleable, which is very suitable to create the flowing shape. The marbles on the other hand, can show the beauty of nature, and the soft white color makes the sculpture even more beautiful. All of these works are involved with the process of cutting and carving. Back in the old days, the artists had to take the chisel and bit by bit to carve out the masterpiece which he had envisioned. These days, we can use the tool to help us achieve the same effect. One of the tools to help create the different shapes is the high precision rotary table.
Before we embark on discussing what a high precision rotary table is, we need to first understand what a rotary table is. In order to maintain the precision in the process of the metal working, humans have designed a type of equipment to help us do the work, the rotary table. In general, the rotary table is an equipment which allows the operator to drill or cut the metal at the exact intervals around a fixed axis. Several types of the rotary tables have utilized a device called the index plates to help the machine perform the function.
Due to its ability to maintain the precision in the metal working, several industries have utilized the rotary table to help them process the metal work in the factories. It is also possible for the people to cut some complex curves with the rotary table, if they set up the machine properly in advance. The rotary table can also perform well with the other equipment. The rotary table is very good at cutting the shapes which are generally considered to be very hard to achieve without the proper tools. For example, it is possible for the rotary table to cut a round piece with a device called the protruding tang. All these features have helped the rotary table become one of the most favorite equipment among the industries, such as the aerospace and automotive industries.

Now that we have learned what the rotary table is, we can now talk about the high precision rotary table. The high precision rotary table is also a type of the rotary table. The function of the high precision rotary table is also to rotate the work piece so the cutting tool can create the contour we desired out of the work piece. However, the high precision rotary table has the ability to achieve great accuracy just as its name implies. There is also a major misconception between the resolution and the accuracy.
It is to most people’s belief that the resolution of the high precision rotary table has to also be the accuracy of the high precision rotary table. A common example is that if a digital readout displays to four decimal places, then the high precision rotary table must also be capable of achieving the accuracy to that same value. Even though for higher accuracy to be achieved, the resolution has to also be high, but there is no guarantee that the accuracy is going to be high. The accuracy is the concept which is the difference between the actual position and the position measured by a reference measurement device. The feedback mechanism such as the rotary encoder, and the drive mechanism can influence the accuracy of the high precision rotary table.
There is also another concept to consider, the repeatability. The repeatability is a concept which is defined as the range of positions joined when the rotary table is repeatedly commanded to one location under the identical conditions. By approaching the point from one direction, and neglect the effects of the hysteresis which is within the system, we can successfully measure the uni-directional repeatability.
