In the process of mechanical processing, the common methods of plate cutting include manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. Manual cutting is flexible and convenient, but manual cutting has poor quality, large dimensional errors, large material waste, large follow-up processing workload, harsh working conditions and low production efficiency. Among the semi-automatic cutting machines, the profiling cutting machine has good quality of cutting workpieces. Because it uses a cutting die, it is not suitable for single-piece, small-batch and large-scale cutting. Although other types of semi-automatic cutting machines reduce the labor intensity of workers, their functions are simple and are only suitable for cutting some more regular-shaped parts. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the efficiency and cutting quality of plate cutting, and reduce the labor intensity of the operator. In some small and medium-sized enterprises in our country, it is more common to use manual cutting and semi-automatic cutting in some large enterprises.

The amount of steel used in my country’s machinery industry has reached more than 300 million tons, and the amount of steel cut is very large; with the development of the modern machinery industry, the requirements for work efficiency and product quality of sheet metal cutting have also increased. Therefore, the market potential of CNC cutting machines is still great, and the market prospects are relatively optimistic.

status quo

1. After decades of development

CNC cutting machines have made considerable progress in cutting energy and CNC control systems. Cutting energy has evolved from a single flame energy cutting to multiple energy sources (flame, plasma, laser, high-pressure water). Jet) cutting method; CNC cutting machine control system has evolved from simple functions, complex programming and input methods, and low automation to a fully functional, intelligent, graphical, and networked control method; the drive system has also changed from Stepper drive, analog servo drive to today’s all-digital servo drive;
The main varieties of CNC cutting machines include the following:

  • CNC flame cutting machine
  • CNC plasma cutting machine
  • CNC laser cutting machine
  • CNC high pressure water jet cutting machine
  • Other special special cutting equipment (such as CNC pipe cutting machine, CNC profile cutting machine, other non-metal special cutting equipment, etc.)

2. The characteristics and application of various types of CNC cutting machines

The CNC flame cutting machine has the ability to cut large-thick carbon steel, and the cutting cost is low, but there are large cutting deformations, low cutting accuracy, low cutting speed, long cutting preheating time, long piercing time, and it is difficult to adapt to full automation Operational needs. Its application is mainly limited to the cutting of carbon steel and large thickness plates, and will gradually be replaced by plasma cutting in the cutting of medium and thin carbon steel plates.

CNC plasma cutting machine, plasma cutting has a wide cutting area, which can cut all metal plates, with fast cutting speed and high efficiency, and the cutting speed can reach more than 10m/min. Plasma cutting under water can eliminate the noise, dust, harmful gas and arc pollution generated during cutting, and effectively improve the working environment. The use of fine plasma cutting has made the cutting quality close to the level of laser cutting. With the maturity of high-power plasma cutting technology, the cutting thickness has exceeded 100mm, which has broadened the cutting range of CNC plasma cutting machines.

The CNC laser cutting machine has the characteristics of fast cutting speed and high precision. The laser cutting machine is expensive and the cutting cost is high. It is only suitable for thin plate cutting and high precision occasions.

The CNC high-pressure water jet cutting machine is suitable for cutting any material (metal, non-metal, composite material), with high cutting accuracy, no thermal deformation, and an environmentally friendly cutting method. Its disadvantages are slow cutting speed, low efficiency and high cutting cost.

Other CNC cutting machines: including CNC pipe cutting machines, CNC profile cutting machines, CNC bevel cutting machines, CNC woodworking cutting machines, these special cutting equipment are mainly used for CNC cutting of various special profiles, and there are not many manufacturers in the market.

Development Trend

With the development of the modern machinery processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and having high-intelligence automatic cutting functions are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern machinery processing industry.

  1. The development of CNC cutting machines. Judging from the application of several general-purpose CNC cutting machines, the functions and performance of the CNC flame cutting machine have been relatively complete. Its material cutting limitations (only carbon steel plates can be cut), slow cutting speed and low production efficiency, its scope of application is gradually increasing. Shrinking, the market cannot have a big increase.The plasma cutting machine has the characteristics of wide cutting range (cutting all metal materials), fast cutting speed, and high work efficiency. The future development direction lies in the improvement of plasma power technology, the cooperation of numerical control system and plasma cutting, such as the increase of power supply can cut Thicker plates; the improvement and improvement of fine plasma technology can increase the cutting speed, cutting surface quality and cutting accuracy; the improvement and improvement of the numerical control system to adapt to plasma cutting can effectively improve work efficiency and cutting quality.Laser cutting machine has the characteristics of fast cutting speed, precision and cutting quality. Laser cutting technology has always been a high-tech that the state supports and promotes its application. In particular, the government emphasizes the need to revitalize the manufacturing industry, which brings development opportunities to the application of laser cutting technology. When the country formulated the medium and long-term development plan, laser cutting was listed as a key supporting technology, because it involved national security, national defense construction, high-tech industrialization and the development of cutting-edge technology, which raised laser cutting to a very high level. The degree of attention is bound to bring great business opportunities to the manufacture and upgrade of laser cutting machines. In the past few years, most of the laser cutting machines sold in China were imported products from abroad, and domestic products accounted for a very small share. With the gradual in-depth understanding and exemplary adoption of laser cutting technology by users, domestic enterprises have driven the development and production of laser cutting machines.
  2. The development of special CNC cutting machines. The CNC pipe cutting machine is suitable for cutting cylindrical orthogonal, oblique, eccentrically intersecting inertial holes, square holes, and elliptical holes on various pipes, and can cut the intersecting inertial lines at the end of the pipe. This type of equipment is widely used in the production of metal structural parts, power equipment, boiler industry, petroleum, chemical and other industrial sectors. The CNC bevel cutting machine is one of the more high-end products in the industry. The rotary bevel cutting function of this type of equipment can meet the requirements of different plate bevels at different angles in the welding process. With the development of my country’s shipbuilding industry, shipyards took the lead in introducing and using CNC plasma cutting machines in China. With the development of technology, domestic and foreign shipyards have been equipped with CNC plasma cutting machines with rotary bevel cutting function to meet the construction requirements of high-tech and high value-added ships.

Concluding remarks

Judging from the application of various CNC cutting machines, the overall level of domestically produced CNC cutting machines has made gratifying progress in terms of technical level and overall machine performance, gradually catching up with the international advanced level, meeting the needs of users, and further improving the market. Competitiveness. Some domestic CNC plasma cutting products have formed their own unique characteristics in many aspects, achieving “automation, multi-function and high reliability”. In some respects, the technical performance of the product even exceeds that of foreign products.

From the perspective of development trend, the CNC flame cutting machine in the CNC cutting machine market will maintain its basic market, the water jet cutting market will increase to a certain extent, and the CNC plasma cutting machine and CNC laser cutting machine will become the mainstream in the plate cutting market Power, special profile CNC cutting equipment, contact and non-contact non-metal special CNC cutting equipment will also have greater room for development, and the entire CNC cutting machine market will continue to expand.

When we go to the insulating glass production line or increase the production variety, we will choose an automatic glass cutting machine, but we should pay attention to the following points when purchasing

1. Cutting accuracy

For the construction industry, it is generally required to be below ±0.5mm; but for automotive mirrors, it is required to be below ±0.Olmm. The cutting accuracy that each machinery manufacturer can provide is generally below ±0. 2mm, but this should not just look at the introduction of the product manual. There should be a complete set of cutting accuracy testing procedures at the time of acceptance, and the accuracy of the actual cut product should be measured. Yes, we usually have more than a dozen test samples. Through the test, we can fully grasp the flatness of the cutting platform and the synchronization control level of the control system.

2. Cutting speed

We can talk about speed only when the cutting accuracy is met. Because the cutting platform is short, it is difficult to judge whether the maximum speed is reached with the eyes. We can use the software simulation function of the servo drive of the cutting machine to check whether the motor speed is up highest. When testing the cutting speed, do not use real cutting, increase the acceleration and deceleration. Each axis can be tested separately or at the same time.

3.Automatic typesetting optimization function

On the side of the cutting machine, taking into account the processing cost and the particularity of the work type, generally will not arrange for highly educated people to do it. This requires the operation of the cutting machine to be simple, easy to understand, and not too complicated, otherwise it will cause The embarrassing situation where one can afford a machine and cannot support a machine. It is best to have the function of avoiding defects, because there are sometimes defective products in the domestic bottom glass. The graphics library for special-shaped cutting should be more and flexible, so that the graphics made by CAD can also participate in typesetting.

4.Easy maintenance

I/0 signals and mechanical sensors should not be equipped with too many, unnecessary switches and indicators should be as few as possible, because once a certain device on the machinery fails, it will affect the use of the cutting machine, and the failure probability of fewer components is low. There are also few lines, which is convenient to find faults and replace parts. It is best to debug the status of each I/0 signal on the screen. Maintenance cost is an important factor that must be considered when purchasing a machine.

5.Save energy

When the cutting size requirements can also be met, choosing energy-saving cutting opportunities will bring many benefits to the enterprise. One is to protect the environment and save energy; the other is to save the daily expenses of the enterprise.

  • 2. Turn on the power, press the button of the host, and check whether the direction of the blade is consistent with the direction of the arrow. If it is reversed, adjust immediately. After the inspection is completed, the rock sample can be clamped for cutting. When the rock sample is clamped, a reliable clamping point should be selected to prevent virtual clamping and false clamping. In order to avoid damage to the tool and rock sample due to rock movement during the cutting process.
  • 3. When clamping irregular rocks, the top pressure method can be used for clamping. Clamping steps: first place the rock sample 8 on the workbench, and then insert the top pressure mobile jig 10 along the T-slot 3, select the distance between the jig and the rock sample, lock the fixture base screw, and move the top rod up and down Bolt 13 to select a reliable clamping point, and then lock the ejector rod moving nut 11, and then rotate the ejector rod until the ejector rod closes the rock sample, and tighten the ejector rod nut 12 at the same time to prevent the ejector rod from cutting. Loose.
  • 4. When cutting the core sample, if there are a lot of rocks, you can press several rock samples with the attached long pressing plate and cut them together to improve work efficiency. The clamping method is as follows: Lay the rock sample 8 flat on the work On the table 6, insert the pressure plate bolt along the T-slot 3, insert one end of the long pressure plate 9 into the square hole on the vertical surface of the worktable, and rotate the adjusting screw 7 and the nut 10 of the pressure plate bolt to compress the rock sample. If there is a slight error in the diameter of the core sample, a thin wooden board can be added to the rock sample so that the long pressing board can press the rock sample. This method is also used when clamping and cutting shaped cuboid and cube rock samples.
  • 5. When working, start the main motor first, and then press the work feed button. When starting to cut, because the rocks are often irregular in shape, the feed speed should be slow at this time, and the blade can be faster after all the blades enter the rock sample. .

When the blade is close to the rock sample, release the button. Then press the work-in button again to perform normal cutting. This can shorten the feed assist time.
  • 7. When cutting the test piece, the feed speed can be adjusted according to the rock hardness before work. When the feed speed is adjusted during the cutting process, knife marks may appear. When cutting harder stones according to the use experience, the speed is generally 40 mm/ About points.


  • 1) When moving the worktable or spindle, the moving speed should be correctly selected according to the distance to the workpiece to prevent collisions when moving too fast.
  • 2) When programming, determine the correct processing technology and processing route according to the actual situation, and prevent the workpiece from being scrapped or cut off in advance due to insufficient processing position or insufficient edge strength.
  • 3) It is necessary to confirm whether the program and compensation amount are correct before thread cutting.
  • 4) Check whether the electrode wire tension is sufficient. When cutting the taper, the tension should be reduced to half of the usual.
  • 5) Check whether the feeding speed of the electrode wire is proper.
  • 6) Choose open processing or close processing according to the actual situation of the workpiece, and minimize the distance between the nozzle and the workpiece on the premise of avoiding interference. During close processing, the distance between the nozzle and the workpiece is generally 0.05 to 0.1 mm.
  • 7) Check whether the jet selection is reasonable, use high-pressure jets for roughing and low-pressure jets for finishing.
  • 8) Pay attention to observe and judge the processing stability when starting the cut, and adjust in time when defects are found.
  • 9) During the processing, the cutting conditions should be inspected and supervised frequently, and the problems should be dealt with immediately
