Punchcutting, which is a cutting style used for various purposes in CNC machines, is the name given to the hole punching process. In short, it is the process of performing various operations on sheet metals according to the determined order of punches. CNC Punchcutting, which is an application used in many sectors, is generally used in a wide range of manufacturing industries such as electrical, machinery and spare parts, electronics, metal goods, automotive, and accessories. Punch cuts are made at a thickness of 8 mm for mild steel plate, 6 mm for stainless steel plate, and 5 mm for aluminum alloy plate products. In addition, cuts with precise measurements are prepared economically and quickly for drilling and forming processes in sheet products such as plastic, copper, and brass.



What is Punchcutting?

Punch cutting is a faster cutting method than other types of cutting. It is one of the most preferred cutting types today, in the 21st century. The reason for this is that it has high part quality and low cost. Punchcutting machines are CNC machines that work with punching logic. Punch cutting has surpassed other classical cutting methods such as laser, plasma, and water cutting. One of the reasons for this is that it is highly effective in cutting the desired shapes. The effect of this is that CNC control is strengthened to include multiple cutting tools. CNC On Punch is a situation where the machines in the company's inventory work with other factories for a certain fee. Especially in CNC subcontracted punch cutting, these charges vary depending on the wear and tear of the machine and over time.

How is Punchcutting Done?

In punch cutting, the sheet metal part is movable while the mold part is fixed. The sheet metal part moves on two axes, known as X and Y. It is transferred to machines known as CNC numerically controlled machines with the help of a 2D CAD program drawn on a computer. It is the processing of sheet metal plates with the help of engines defined on the machines with coding known as G coding. 37 dkp sheet metal is generally used as standard in the markets. In addition, these sheets can be processed from DKP sheets to aluminum sheets with a thickness of 1 mm to 6 mm.

Generally in the market, On Contract Punch cutting simulation is made on the machine by the person responsible for the CNC Punch program upon the arrival of technical drawings or parts from customers. Criteria such as whether CNC subcontracted punch cuts are suitable for post-production, machinability, and pricing are determined. This information is shared with the sales department and presented to the customer. The agreement is made with the customer's approval. The products are produced with or without materials. If uninterrupted cutting is required for the quality of your products, punch laser cutting can be considered. However, if you consider the cost factor, CNC punch cutting is inevitable. Especially in CNC On Contract Punch Cutting, 1 to 3 mm sheet metal sheets are cut at affordable costs. CNC punch cutting is preferred, especially if a structured structure is desired. While laser cuts are precision cuts with thicker materials, their costs are quite higher compared to CNC Punch Cutting. If CNC Punch Cutting is desired Almost all shapes can be made.

They are made with 36 stations and mold sets on the turret of the CNC Machine. For this, you can request technical information from companies. There are different prices for On Contract Punch Cutting depending on the facilities. These differences are due to changes in personnel, machines, programs, and existing molds. Machines are one of the most important factors. While some machines make 250 strokes per minute, some machines go up to 1200 strokes. Strokes that affect the part output speed are also reflected in the hourly wage of the machine. It also affects the number of part speeds in the program prepared for the machine. If an inexperienced personnel makes the program, the processing speed of the machine slows down, and thus the part comes out late. The materials to be cut in CNC Punch cutting are approximately 0.5 mm to 4 mm thick. If desired, it can be up to 6 mm thick. However, this may strain the machine.

The most preferred reason for CNC Punch cutting is the forming process. This process is connected to the station with special molds on the machine and can be done easily. Considering this shaped structure, the CNC punch starts from the ventilation shutter to many special molds. The delivery time of the production is the shortest. Of course, it may vary depending on the intensity of production. The more stations there are, the faster the license plate programming. This leads to a shortening of the cutting time. These stations are in the form of a-b-c-d. The most preferred and used station is (C). In CNC contract cutting machines, the body can be C or D. This ensures the construction of the machine. The body of CNC Punch machines has a cast structure. The body is aged with aging frequency. This minimizes deformities that will occur over time. Hydraulic units are German HD units but may differ from electronic Panasonic or Fanuc. If a shaped structure is considered and aluminum will be cut on a punchcutting machine, diesel oil should be applied to the aluminum material. Thus, mold shrinkage is prevented.

If the contract cutting machine is to be used in subcontract work, it is very important that the machine is new, not worn, and clean. Having a new Contract Cutting Machine is a factor that affects the delay in malfunctions and damages that may occur. The fact that the CNC Punch Machine is new will ensure that axial wear is at a minimum level and cutting slippage caused by the sensitivity of the shaft will be minimized.

If the cost factor is taken into consideration, CNC Punch Cutting may be preferred. Because mold costs are lower and efficient results can be achieved in a short time. It is also possible to process large sheet metal plates. If there are too many holes in the material and product to be cut, laser cutting will not give good results. Punch cutting should be preferred. It also offers the opportunity to shape thin sheets with the help of molds with special forms. Its most important feature is that it provides flexibility with its cord mold. In short, it gives very good results at a low cost. It is used to cut sheet metal at affordable costs. If you prefer to achieve both quality and economical results; Considering this, CNC punch cutting and Contract Punch cutting are an inevitable choice.
