# What Are 4th and 5th Axis Rotary Tables?

Posted on Jan 16, 2021

The 4th and 5th axis rotary table is also a type of rotary table. The 4th and 5th axis rotary table is also utilized to drill or cut the metal at the exact intervals around a fixed axis.

Imagine yourself walking down a straight street. After about 5 minutes of walking, you come across a huge obstacle which is located on the street. What do you do then? One of the answers is to go around the obstacle and continue your journey. It is very easy for people to go around something that stays in their way, so they can continue their routine unencumbered.

To go around an obstacle may seem easy in our daily life, but it has proven to be quite difficult for the machine. Back in the old day, if the machine meets an obstacle while processing or cutting the workpiece, it will have to either cut through it or give it up. These days, people have invented equipment to help us go around the obstacle while cutting or processing the workpiece. This brings us to the subject of today, the 4th and 5th axis rotary table.

## What Is a Rotary Table?

Before we start to elaborate on what a 4th and 5th axis rotary table is, we have to first comprehend the rotary table. A rotary table is a type of equipment that is designed to reach a certain precision. The rotary table has the ability to permit the operator to drill or cut the metal at the exact intervals around a fixed axis. Some types of rotary tables will adopt a device called the index plates to perform the function during the process of indexing operations.

There is also a device called the dividing plates which are commonly utilized by the rotary table to make the regular work positioning at divisions possible. The functions of the rotary table are versatile. For example, people can drill the holes at the same distance on a circular flange by the help of the rotary table. The rotary table can also cut the curve which can be elaborated if the rotary table is set up properly in advance. Several industries have adopted the rotary tables to help them with the cutting or the processing of metal workpieces. The rotary tables can be used in industries such as aerospace and automation.

## The Difference Between 4th Axis and 5th Axis

Now that we know about the rotary table, we can now explain another concept of the 4th and 5th axis rotary table. For those who first see the name of the 4th and 5th axis rotary table, it can be quite confusing. So what is the difference between the 4th axis and the 5th axis?

### ● 4th axis

The 4th axis machining is a way to process the workpieces. In the 4th axis machining, the workpiece will be held in the same position while the cutting tool performs along the XYZ plane to trim away material. Aside from this, the 4th axis machining also possesses an additional rotary movement around the X-axis, which is sometimes referred to as the A axis. This rotation will let the workpiece be cut and processed around the B axis. This process is very useful and beneficial when it is important to make the holes or cuts on the sides of a workpiece. The addition of a fourth axis will help to flip a workpiece over automatically. This way, the machine can cut out the excessive or unwanted material from both sides. In general, the 4 axis machining is very versatile and can be used for the process such as the engraving of curved surfaces, the continuous cutting, and the intermittent cutting.

### ● 5th axis

The 5th axis machining, on the other hand, allows the workpiece to be processed automatically from five sides at one time. The 5th axis machining is often utilized in the industries such as the automobile, aerospace, and boating industries. The 5 axis machining is an important technique to be used when the components need better intricacy and quick precision.

## What Are 4th Axis and 5th Axis Rotary Tables?

Now that we have gone through the elements which comprised the 4th and 5th axis rotary table, we can now discuss what is the 4th and 5th axis rotary table. The 4th and 5th axis rotary table is also a type of rotary table. The 4th and 5th axis rotary table is also utilized to drill or cut the metal at the exact intervals around a fixed axis. The difference between the 4th axis rotary table and the 5th axis rotary table is the way it processes the workpiece. As in the 4th axis machining, the workpiece can be processed on 4 sides automatically. On the other hand, the 5th axis rotary table utilized the 5th axis machining technique which allows it to process the workpiece at 5 sides at the same time.
