4th and 5th axis CNC rotary table

The 4th and 5th axis CNC rotary tables are the components that help CNC machine tools achieve multi-axis machining techniques. With 4th and 5th axis CNC rotary tables, both precision and efficiency can be attained in the automation of machine tools.

Humans are very peculiar creatures. We have several abilities that other animals do not have. For example, we have the technology to help us survive better and to deal with the arduous task that we found very hard to do. We also have very refined tools and equipment which will come in handy when we need to repair the broken objects or to produce the products. Humans have invented so many things that we are now a lot more efficient in not only the production of the products but also the life path. 

All of these tools and equipment are specifically designed to deal with certain tasks. For example, we need the conveyor to help us transfer the objects so we do not have to carry them one by one. Since metals are one of the most important materials for human civilization, people have managed to invent several pieces of equipment to deal with the metal too. One of this equipment is the main subject of today, the 4th and 5th axis CNC rotary table.


What Is a Rotary Table?

Before we start to discuss what a 4th and 5th axis CNC rotary table is, it is very important for us to understand the rotary table. In the industries, almost all people are hoping their equipment can live up to one prime quality, the precision. The precision is so important that, if the machine is precise, the products that it processes or produces will all be rendered unusable. That is the reason why the industries are continuously in search of the equipment which is capable of reaching such precision. 

The rotary table is a type of equipment that is capable of reaching high precision. That is also one of the reasons why people can see the rotary table being applied to several different industries as the equipment to process the metal workpiece. In general, the rotary table is the type of equipment that is capable of allowing the operator to drill or cut the metal at the exact intervals around a fixed axis. 


What Is CNC? 

Now that we have learned about the rotary table, let’s now discuss the system of the CNC. The system of the CNC is actually the abbreviation of the Computer Numerical Control. The Computer Numerical Control is the type of system which has helped people save a lot of time and cost. In the system of the Computer Numerical Control, there is a coded programmed instruction that is utilized to process the workpiece. With the help of this coded programmed instruction, the system of the Computer Numerical Control can process the workpiece all by itself. This way, people will no longer need to appoint an operator to supervise the processing of the workpiece.

What Is the 4th and 5th Axis?

Now we are going to discuss the most important part before we move onto the 4th and 5th axis CNC machine. These two actually are both the technique to process the workpiece. The only difference is that the 5th axis has one more extra side to process the workpiece. In the 4th axis machining, the workpiece will be held in the same position while the cutting tool works on the workpiece along the XYZ plane to trim away the material. Aside from this, the 4th axis machining also possesses an additional rotary movement which is around the X-axis. This additional rotary movement is also referred to as the A axis. In general, the 4 axis machining can be used in so many ways and it can also be used for the process such as the engraving curved surfaces, the continuous cutting, and the intermittent cutting. On the other hand, the 5th axis machining will let the workpiece be processed automatically from five sides at one time. There are several industries that utilized the technique of the 5th axis machining as the way to process the workpiece, such as the automobile, the aerospace, and the boating industries.

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

Having discussed the elements of the 4th and 5th axis CNC rotary table, it is not hard to understand what they are. The 4th and 5th axis CNC rotary tables are the types of rotary table which have utilized the system of the CNC as the way to process the workpiece. Just as I mentioned earlier, there is one difference between the 4th and 5 the axis, which is the amount of the sides that are available to process the workpiece. In the CNC 4th axis rotary table, the workpiece can be processed simultaneously at 4 sides. However, at the CNC 5th axis rotary table, the workpiece can be processed simultaneously at 5 different sides. In general, the 4th and 5th axis CNC rotary table is a very important metalwork processing equipment among the industries.
