# Pneumatic Indexer

Sometimes people hope themselves to possess a certain type of superpower. Some people want to be able to fly in the sky. Some people want to be able to read minds. Some people want to be able to see the future. All of these sound very interesting and cool. What if you can transfer yourself to anyplace in the world with just a few seconds? This might sound like science fiction, but the scientists have been looking for a way to move objects or even organisms in a relatively fast way.

But the speed of the transportation these days has been so much faster than what it was back in the old days. People used to spend months traveling from one place to another, while we can just spend several hours traveling to another country. But not just the speed of the transportation that humans want to improve. People also want to have industrial equipment which can move fast and achieve great precision. This brings us to the main subject of today, the pneumatic indexer.

## What Is the Index Mechanism?

In order to understand what is the pneumatic indexer, we have to first understand the mechanism that functions behind the pneumatic indexer, the index mechanism. Indexing Mechanism is a type of mechanism which is mainly utilized for dividing the periphery of a work piece into several numbers of equal parts if required. In order for the index mechanism to function, a special equipment called the index head is required to perform the work. Indexing head is sometimes also referred to as the dividing head or spiral head. The index mechanism is a kind of equipment which is specially designed to help a work piece to be circularly indexed. There are several industrial applications for the index mechanism. For example, the index mechanism can be applied to cut gear teeth accurately. It is also possible for the index mechanism to be used for the machining of the flutes of a milling cutter, the milling of the curved slots, and the drilling of a bolt hole circle around the circumference of a part.

## What Is the Pneumatic System?

Now that we know about the mechanism that works behind the pneumatic indexer, we can now move on to discuss the system that powers the pneumatic indexer, the pneumatic system. The pneumatic system is the type of the system which utilized the compressed air as the means of transmitting and controlling the energy. Several applications of the pneumatic system can be found in the industries. To most of the pneumatic systems, the constant supply of the compressed air is very vital. Since the pneumatic indexer relies on the compressed air to perform the function. Within the system, there is an air compressor which will provide the compressed air. The compressor will gather the air from the atmosphere and then put the air in a high pressure tank which is called the receiver. Through a bunch of the pipes and valves, this compressed air will be supplied to the system.

## What Is a Pneumatic Indexer?

Now that we know about what is the indexing mechanism and the pneumatic system, we can now discuss the pneumatic indexer in depth. It is very important for the industries to have an equipment which is capable of achieving high accuracy and moving fast. The pneumatic indexer is this type of equipment. Within the pneumatic indexer, there is a pneumatic indexing drive which is capable of achieving the repetitive rotary indexing with no accumulating error. The pneumatic indexer is usually performing under two phases. The pneumatic indexer is usually plumbed. This will help keeping the pneumatic indexer in the locked condition when it is in the normal state of the control valve.

When the process of working is commenced, the work piece can then be moved, the control valve will also be shifted, and the pneumatic indexer will reset internally. This way, it will help the shaft to rotate freely in the forward direction. However, there are also several factors which will interfere with the performance of the pneumatic indexer. For example, if the work piece has the weight imbalance biased toward the reverse direction, this will limit the performance of the pneumatic indexer. Besides, the pneumatic indexer also did not possess the ability to decelerate the load directly. This is the direct result of the function of a device called the one-way clutch, which is utilized to permit the rack and pinion to reciprocate while the shaft goes in one direction only.
