How to choose the right cutting method

In the field of modern industrial manufacturing, cutting is one of the basic processes with a large amount of applications and a wide range of applications. The cutting methods include punching, shearing, flame cutting, electric discharge machining, water cutting, plasma cutting and laser cutting. Each cutting method has its own advantages, but also has certain limitations.

How to choose the right cutting method

The efficiency and quality of cutting will directly affect the efficiency and quality of production. The following factors should be taken into consideration when selecting appropriate cutting equipment:

1. Type, thickness and format of cutting material

2. The size of cutting volume and requirements for cutting speed

3. Requirements for cutting accuracy, requirements for material deformation, and size of secondary processing

4. Can we use optimized nesting software to improve material utilization

5. One-time equipment investment, maintenance cost, whether additional investment such as mold is needed, and comprehensive comparison between equipment investment and economic benefits

CNC plate shearing machine: it is often used to cut the blank with straight edge, and the accuracy is poor.

CNC punch: when stamping parts, the punch requires a variety of dies, and each shape or size requires a pair of dies, which greatly restricts the modification and updating speed of the machine tool. Generally, the workpiece thickness of the CNC punch is less than 10mm

CNC wire cutting machine: with high processing accuracy, it is suitable for processing small batches and multiple types of parts, reducing mold production costs and shortening production cycle. The disadvantages are that the processing surface is small, the processing speed is slow, and the molybdenum wire or copper wire is easy to break after using for a period of time.

Compared with the traditional processing equipment, the laser cutting machine has the following characteristics and advantages: narrow cutting seam, small deformation, high accuracy, fast speed and high efficiency. First, laser light energy is converted into amazing heat energy and kept in a small area, so laser cutting can provide: narrow straight edge slits; The smallest heat affected zone adjacent to the trimming; Minimal local deformation. The laser beam does not exert any force on the workpiece. It is a non-contact cutting tool, which means that the workpiece has no mechanical deformation; There is no tool wear or tool replacement; It is not necessary to consider the hardness of the material to be cut, that is, the laser cutting ability is not affected by the hardness of the material to be cut, and the material with any hardness can be cut. The laser beam has strong controllability, high adaptability and flexibility, so it is convenient to combine with automatic equipment, and it is easy to realize the automation of cutting process; Because there is no restriction on cutting workpiece, the laser beam has infinite profiling cutting ability.
