Thanks to the technological development, the production processes of companies have become more efficient and this has helped them reduce their costs. One of these developments is the popularization of using punch machines, which are used for various purposes in CNC machines, as a cutting and shaping process. CNC punch process, which is an application used in many sectors, is generally used in manufacturing industries such as electricity, machinery and spare parts, metal works, automotive, accessories. Punch machines play an important role in completing these processes perfectly.

Punch cuts are applied with a thickness of 6 mm in sheet metal, 3 mm in stainless steel sheet and 3 mm in aluminum alloy sheet products. Moreover, these machines complete the process by cutting plates such as copper and brass economically and quickly in drilling and forming processes.

In addition to these, the functions of punch cutting and punch machine are also among the topics of interest.

In order to obtain higher part quality and lower the costs, punch machines are used for cutting sheet metals. Working with the punching logic, these machines can be used for various processes as well as cutting methods such as plasma, laser and water jet. Machines powered by CNC control consist of more than one cutting tool. Therefore, the desired shape can be obtained. In this article, as Durmazlar, we will answer in detail your concerns about punch cutting and punch machines.

What Is A Punch Machine?

Punch cutting is a faster cutting technique than the others. It is one of the most preferred cutting types today. The reason behind this preference is beacuse this cutting technique has higher part quality and less cost. Punch cutting machines are also known as CNC machines working with punching logic. In addition to these, punch cutting is more advanced than laser, plasma and water cuttings, which are other classical cutting methods. One of the main reasons for this is that punch cutting has a great effect on cutting the desired shapes.

Its effect is related to the strengthening of CNC control and the inclusion of more than one cutting tool. Generally, the punch machine system is realized by implementation various processes on sheet metal in a certain order of molds suitable for various purposes on the turret. The mold part is fixed and the sheet metal is movable.

How Does Punch Cutting Work?

In today’s world, punch cutting process is one of the most important applications companies carry out. In addition to this, how the punch machine works is also a question wondered by many people. The process can be defined as the punches in the CNC punch machine for various purposes performing various operations on sheet metal in a certain order. Also, while the mold part is fixed, the sheet metal part is movable. The sheet metal moves on two axes. It is extremely important that the movements in these axes are carried out with precision. Where the molds will process the sheet is specified in the program prepared beforehand and uploaded on the machine.

What Are The Advantages Of Punch Cutting?

There are many advantages of punch cutting process. One of them is that it cost less than other cutting types such as laser cutting. Punch machine is much faster than other alternatives for in-part geometrical cuts on sheet metal.

How To Make Punch Cutting?

As stated before, in this cutting technique, the sheet metal part is movable while the mold part is fixed. The sheet metal moves on two axes known as X, Y. 2D drawings are transferred to the machine with the CAD program.

The processing of sheet metal plates with the coding known as G coding and the motors on the machines are one of the components of this process in general. In addition, these sheets can be processed from 1 mm to 6 mm thickness. In addition, it can be applied to various sheets like scoured steel sheet and aluminum sheet.

Generally, in punch cutting, technical drawings or parts received from customers are designed by the person in charge for the punch program in the machine. With these cuttings, criteria such as whether they are suitable for production, machinability and pricing are determined. However, if punching marks are not desired on the periphery of your products, a punch-laser machine can be preferred.

Punch machine has a total of 28 stations, 25 fixed stations on the turret and 3 index stations. Of these 28 stations, 11 are A, 11 are B, 2 are C, and 4 are D stations.

It is very important that all of the programs are designed and implemented by a professional. If an inexperienced personnel makes the programming of the devices, the processing speed of the machine slows down. Therefore, the completion of the product takes longer than normal. The materials to be shaped in the punch machine are approximately 0.5 mm to 6 mm in thickness.

One of the reasons why the punch machines are preferred more is the forming process. This process can be performed by connecting the special molds in the machine to the station. This shaped structure includes many special moulds, especially the punch louvre.

The more stations, the greater the variety of production.  This enables the cutting process to be completed much quicker. These stations are in the form of A-B-C-D. The most used among these stations is the station A. The body of punch machines are made of a cast structure. This structure reduces the number of deformities that may occur over time. If a formed structure is aimed and aluminum will be cut in a punch cutting machine, a special coating process is applied to the molds to be used in aluminum cutting.
