*Comparison of advantages and disadvantages of various cutting processes*

As a traditional cutting equipment, there are mainly (CNC and non-CNC) shearing machine, punch, flame cutting, plasma cutting, high pressure water cutting and so on. These devices occupy a considerable market share in the market, one of them is known, the other is cheap, although they are relatively inferior to laser cutting and other modern technology is very obvious, but they also have their own unique advantages.

1. (NUMERICAL control) shears Because it is mainly linear cutting, although a knife can cut up to 4 meters of sheet metal, but it can only be used in the line cutting sheet metal processing. Generally used in the plate after cutting only need straight line cutting industry.

2. (CNC/turret) punch press Have more flexibility in curve machining, a punch can be one or more sets of punch, round, or other special requirements, you can work out specific sheet metal workpiece at a time, one of the most common is the chassis cabinets industry, they asked for the processing technology of main is linear, square hole, round hole cutting, such as fixed pattern is relatively simple. They mainly face the carbon steel plate below 2mm, and the width is generally 2.5m×1.25m. Thickness of more than 1.5mm stainless steel due to the material viscosity is too much more expensive die, generally do not use a punch. The advantage is that the processing speed of simple graphics and thin plates is fast, the disadvantage is that the ability of punching thick steel plates is limited, even if the workpiece surface is collapsed, the cost of die, die development cycle is long, high cost, the degree of flexibility is not high enough. More than 2mm steel plate cutting processing abroad generally use more modern laser cutting, without the use of punch, a thick steel plate punching shear surface quality is not high, two thick steel plate needs more tonnage punch, waste of resources, three thick steel plate when the noise is too big, is not conducive to environmental protection.

3. Flame cutting As the original traditional cutting method because of its low investment, the past processing quality requirements are not high, the requirements are too high to add a machining process can be solved, the market holding is very large. Now it is mainly used to cut thick steel plates over 40mm. Its disadvantage is that the cutting heat deformation is too large, the slot is too wide, waste of material, and processing speed is too slow, only suitable for rough processing. “Comparison of advantages and disadvantages of various cutting processes”

4. Plasma cutting and fine plasma cutting Similar to the flame cutting, the heat affected zone is too large, but the accuracy is much larger than the flame cutting, speed also has an order of magnitude leap, has become the main force of plate processing. Domestic top fine CNC plasma cutting machine's actual cutting precision of the on-line has reached the lower limit of laser cutting, cutting was 22 mm carbon steel sheet at a speed of more than 2 meters per minute, and the cutting face smooth level off, the slope of the best can be controlled within 1.5 degrees, the thermal deformation in cutting thin plate is weakness is too big, slope is bigger also, It can't be used when the precision is high and the consumables are more expensive.

5. High pressure water cutting Is using the doped silicon carbide in high speed water jet cutting of sheet metal, it almost no limit of material, the thickness of the cutting is almost can reach more than 100 mm and for ceramics, glass, etc. With hot cutting material can also be cut, easy to burst when high reflection for laser materials such as copper, aluminum water knife can be cut, and laser cutting has greater obstacles. The disadvantage of water cutting is that the processing speed is too slow, too dirty, not environmentally friendly, consumables are also higher.

6. Laser cutting It is a technological revolution of processing blanking technology. Laser cutting flexibility, high cutting speed, high production efficiency, short production cycle, for customers to win a wide range of markets. Laser cutting without cutting force, processing without deformation; No tool wear, good material adaptability; Whether simple or complex parts, can be cut by laser precision rapid prototyping; Its narrow cutting seam, good cutting quality, high degree of automation, simple operation, low labor intensity, no pollution; Can realize cutting automatic layout, nesting, improve the material utilization rate, low production cost, good economic benefits. The effective life of the technology is long, at present in foreign superstructure 2 mm plate mostly using laser cutting, many foreign experts agree that the next 30 to 40 years is the golden period of laser processing technology development.
