In the field of metal manufacturing, the continuous pursuit of more efficient and precise production processes is the key to maintaining the competitiveness of enterprises. As a Chinese custom metal parts manufacturer with 28 years of rich experience, Kailai Machinery has always been committed to exploring innovation and providing customers with the best products and services. Today, let us take a deeper look at the cutting-edge manufacturing technology of combining metal stamping with machining.

Metal stamping: the cornerstone of efficient forming

Metal stamping is a manufacturing process that uses dies and presses to apply pressure to metal sheets to cause plastic deformation or separation to obtain parts of the desired shape and size. This process has many significant advantages.

Production efficiency: From the perspective of production efficiency, metal stamping is a model of efficiency. Through automated stamping production lines, dozens or even hundreds of parts can be produced per minute, which makes large-scale production possible and greatly reduces production costs. In the automotive manufacturing industry, a large number of metal parts such as body panels, engine brackets, etc. are quickly produced through metal stamping processes.

Material utilization: Metal stamping also performs well in terms of material utilization. Advanced progressive die technology can achieve a material utilization rate of more than 85%, which greatly saves raw material costs compared to the material utilization rate of about 40% in traditional cutting. This not only conforms to the concept of sustainable development, but also reduces production costs for enterprises.

Parts performance: Metal stamping can also give parts excellent performance. During the stamping process, metal sheets will undergo cold work hardening, which will increase the strength of the parts by 20% - 50%, which is crucial for some parts with higher strength requirements. At the same time, using high-precision molds, the dimensional accuracy of stamping parts can be controlled within ±0.05mm, which can meet the production needs of most precision parts.

The core processes of stamping include blanking, bending, drawing, piercing and shaping. The punching process can cut the plate into a precise contour, such as the round cover of the can is completed by the punching process, with an accuracy of ±0.01mm; the bending process uses a V-shaped die to bend the plate, such as the right angle edge of the chassis shell is formed in this way; the drawing process can turn the flat plate into a deep cavity, such as the manufacture of stainless steel pots; the punching process can form a vertical edge at the edge or hole of the plate, which facilitates subsequent assembly; the shaping process locally pressurizes the parts to eliminate springback, so that the parts can reach higher precision requirements, and is often used in the processing of coins, precision gear teeth, etc.

Machining: The guarantee of precision manufacturing

Computer numerical control machining (CNC Machining), which is what we often call machining, is a technology that uses digital programs to control machine tools for precise cutting, drilling, milling and other processing operations. It brings unprecedented precision and complexity to the manufacturing of metal parts.

Parts accuracy: The precision of machining is amazing, and can reach micron-level accuracy. In the field of aerospace, the manufacturing of key parts such as engine blades requires extremely high precision. Machining can meet this demanding requirement and ensure the performance and reliability of parts. Through pre-written programs, machine tools can accurately control the movement trajectory of the tool to achieve the processing of complex shapes, whether it is a polyhedron, a curved surface or a part with various precision hole systems.

Flexibility: Machining has a high degree of flexibility. Only by modifying the program, you can quickly switch to produce parts of different specifications and shapes, without the need to frequently change molds and fixtures like traditional processing, which greatly shortens the production cycle and improves production efficiency. This makes small-batch, multi-variety customized production possible, meeting the personalized needs of different customers.

When processing complex parts, the advantages of machining are more obvious. For example, for some parts with complex internal structures, such as the cylinder block of an automobile engine, machining can accurately process each cavity, water channel and oil channel to ensure the normal operation of the engine.

Combining the two: complementary advantages to create greater value

Combining metal stamping with machining can give full play to the advantages of both and achieve the effect of 1 + 1 > 2. This combination is particularly important in the production of some metal parts that have high requirements for precision and strength.

First, the metal sheet is initially formed through the metal stamping process to quickly obtain the approximate shape of the part. This step takes advantage of the high efficiency and low cost of metal stamping and can produce a large number of semi-finished products in a short time. Then, the stamping parts are finely processed by machining, the key dimensions are accurately controlled, and complex hole systems, threads and surface shapes are processed to ensure that the parts meet high precision requirements.

In the manufacture of metal casings for electronic equipment, the metal sheet is first stamped into the basic shape of the casing through the stamping process, and then the frame is precisely milled by machining to process high-precision assembly holes and surface textures, so that the casing has good strength and appearance, and can meet the high-precision assembly requirements with internal parts. This combined production method not only improves production efficiency, but also reduces production costs, while ensuring product quality and performance.
