Punch press is a kind of punch press. In national production, stamping technology has been more and more widely used because of its advantages of saving materials and energy, high efficiency, low technical requirements for operators and products that cannot be machined through various molds.
Stamping production is mainly aimed at sheet metal. Blanking, punching, forming, stretching, trimming, fine punching, shaping, riveting and extruding parts can be made through the die, which is widely used in various fields. For example, we use switch sockets, cups, cabinets, plates, computer cases, and even missile planes ... there are many accessories that can be produced by punching machines through molds.
With the development of modern machining industry, the requirements for cutting quality and accuracy are constantly improving, and the requirements for improving production efficiency, reducing production costs and having high intelligent automatic cutting function are also increasing. The development of CNC cutting machine must adapt to the development requirements of modern mechanical processing industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines and water cutting machines. Laser cutting machine has the fastest efficiency, the highest cutting accuracy and generally smaller cutting thickness. The cutting speed of plasma cutting machine is also very fast, and the cutting surface has a certain inclination. The flame cutting machine is aimed at thick carbon steel. Laser cutting machine has the fastest efficiency, the highest cutting accuracy and generally smaller cutting thickness.
Electric welding machine Electric welding machine uses the high-temperature arc generated when the positive and negative electrodes are short-circuited instantly to melt the solder on the electrode and the material to be welded, so that the contacted materials are combined. Its structure is very simple, it is a high-power transformer. Welding machines can be generally divided into two types according to the types of output power, one is AC power supply and the other is DC power supply. They use the principle of inductance, which will produce a huge voltage change when it is turned on and off, and use the high-voltage arc generated when the positive and negative electrodes are short-circuited instantly to melt the solder on the electrode, thus achieving the purpose of atomic bonding.
Angle grinder, also known as grinder or disc refiner, is a kind of abrasive tool for cutting and polishing FRP. Angle grinder is a portable electric tool that uses FRP for cutting and polishing. Mainly used for cutting, grinding and brushing metal and stone.
The common models of angle grinder are divided into 100 mm (4 inches), 125 mm (5 inches), 150 mm (6 inches), 180 mm (7 inches) and 230 mm (9 inches) according to the specifications of accessories used, which are small sizes used in Europe and America.
