CNC Turret Punching Machines: features, types, and scope of application

CNC Turret Punching Machines are a type of sheet bending equipment designed for cutting sheet metal for the production of flat workpieces (parts, products, spare parts). Compared to angle-cutting machines, universal machines, and guillotine shears, coordinate punching presses allow you to produce complex contours with minimal time and high accuracy. CNC Turret Punching Machine The CNC Turret Punching Machine is designed for: Cutting-shaped holes. Cutting of contour products from sheet metal. The equipment is used in metalworking and manufacturing enterprises that produce products (blanks, parts, products, etc.) made of sheet metal. The use of machines is possible for working with both ferrous and non-ferrous metals. Most often, the press is used in the manufacture of metal furniture, including warehouse and retail, advertising structures and elements of outdoor and interior advertising. The machines are widely used in the field of automotive, electronic, electrical production, as well as in all industries, regardless of the volume of production, where sheet metal cutting operations are performed. Features and varieties of CNC Turret Punching Machine The following basic parameters are taken into account when selecting a coordinate punching press: The impact force of the hydraulic head. For professional industrial equipment, the parameter value can reach 30 tons when working with sheets up to 6.5 mm thick and higher. Type of punching mechanism. It mainly uses a hybrid punching mechanism (controlled by a servo head), which ensures the most efficient, high-quality, and safe operation.

Basics of metal bending

To date, sheet metal bending is carried out in various ways. The most widely used machines are the Press-brake type. The popularity of using this technology is due to the following features. On the same equipment, you can make parts of different configurations from different materials and different thicknesses. High production flexibility — most parts are manufactured without changing equipment or changing tools. Moreover, often the tool does not change at all, while in production there may be a large number of parts that differ both in configuration and in material/thickness. High performance. Low cost of equipment and cost of production. Applicability of process automation. At the same time, the possibilities of such a technological process cannot be unlimited. The main limiting factors, or a combination of them, are: material properties; tool features; knowledge and skills of technologists and operators; Let’s consider the main, most important issues of sheet metal bending on press-brake machines. Deformation of the metal Bending on sheet bending presses is based on the 3-point principle. The sheet is based on 2 matrix points. The punch presses on the sheet between the 2 points of the matrix, forming a third, central point. When the punch is lowered, the central point of the sheet is lowered along with it, and the lower side surfaces of the sheet slide along the radii of the V-shaped hole of the matrix. The material is somewhat compressed at the place of the punch pressure and is significantly stretched from the lower side of the sheet. Also, the material is deformed at the point of sliding along the matrix — there are visible or invisible traces of deformation (indentation). Schematic representation of metal deformation during bending The length of the sweep in the direction perpendicular to the bend line is always increased. In this regard, the scan length is made less than the sum of all the sides. The elongation of the workpiece at each bend depends on: thickness and type of material, bending angle,

The main areas of use of stainless steel

Mechanical engineering. The mechanical properties of stainless steel are widely used in the manufacture of machine tools and equipment for industrial enterprises, as well as in the automotive industry. At the same time, austenitic and ferritic types are most often used. Chemical industry. This area of production involves the use of aggressive substances, for the storage of which containers and specially designed equipment are required. For their manufacture, austenitic alloys are used. At the same time, pipes, equipment, and vessels are not exposed to chemicals, so they retain their performance characteristics.Power engineering. In this industry, only materials with high strength are used, since the reliability of all working units is particularly important. Pulp and paper industry. The equipment for this industry is almost entirely made of stainless steel. Food industry. Today, high demands are placed on the production process, transportation, and storage of products. For the manufacture of equipment, only stainless steel, glass, and a number of types of plastic can be used, which give a high level of hygiene
