Cutting machine introduction

Cutting machine is divided into flame cutting machine, plasma cutting machine, laser cutting machine, water cutting and so on.

The laser cutting machine is the fastest, the highest cutting accuracy, and the cutting thickness is generally small. Plasma cutting machine cutting speed is also very fast, the cutting surface has a certain degree of slope. Flame cutting machines are designed for thicker carbon steel materials. The range of applications for cutting machines There are currently metal and non-metal industries for cutting machine applications. In general, the non-metal industry is more meticulous, such as cutting stone cutters, water cutting machines, saw cutting machines, cutting cloths and plastics. Laser cutting machine for chemical fiber products, blade type, cutting machine, cutting metal materials, there are flame cutting surface, plasma cutting machine, flame cutting machine which is divided into CNC flame cutting machine, and manual two categories, manual categories , Small car, semi-automatic, pure manual, CNC, Gantry CNC cutting machine, cantilevered CNC cutting machine, desktop CNC cutting machine, intersecting CNC cutting machine and so on!

The cost of flame cutting machine is relatively low again. Plasma cutting machine has the lowest cost (per calculation)!

Metal cutting machine foreground

Cutting machine Currently, CNC flame, plasma cutting machine holds a large part of the user, and later fine plasma, laser cutting will replace the front, become the mainstream cutting machine, because they are environmentally friendly, cutting speed, cutting quality!

CNC cutting machine is the use of digital programs to drive the movement of the machine tool. As the machine tool moves, the cutting tool is randomly equipped to cut the object. This mechatronic cutting machine is called a CNC cutting machine.

Application and Development

I. Overview

In the machining process, there are manual cutting, semi-automatic cutting and CNC cutting. The manual cutting is flexible and convenient, but the manual cutting quality is poor, the dimensional error is large, the material waste is large, the follow-up processing workload is large, and the labor conditions are harsh, and the production efficiency is low. The contour cutting machine in the semi-automatic cutting machine has good quality for cutting workpieces. Because of its use of cutting dies, it is not suitable for cutting single pieces, small batches and large pieces. Although other types of semi-automatic cutting machines reduce the labor intensity of workers, their functions are simple, and they are only suitable for the cutting of some parts with a relatively regular shape. Compared with the manual and semi-automatic cutting methods, the numerical control cutting can effectively improve the efficiency and cutting quality of the plate cutting and reduce the labor intensity of the operator. At present, some small and medium-sized enterprises in China even use manual cutting and semi-automatic cutting methods in some large enterprises are still relatively common.

At present, the use of steel in China's machinery industry has reached more than 300 million tons, the amount of steel cutting is very large; with the development of modern machinery industry, the work efficiency and product quality requirements for sheet metal cutting and processing are also increasing. Therefore, the market potential of CNC cutting machine is still very large, and the market prospects are more optimistic.

Second, the status quo

1. After decades of development, CNC cutting machines have made great progress in cutting energy and CNC control systems. Cutting energy has been developed from a single flame energy cutting to a variety of current energy sources (flame, plasma, laser, etc.) (High-pressure water jet) cutting method; CNC cutting machine control system has been developed from the original simple functions, complex programming and input methods, the degree of automation is not high to have a full-featured, intelligent, graphical, networked control mode; drive system also From the 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 of various types of CNC cutting machine and its application

CNC flame cutting machine, cutting with a large thickness of carbon steel cutting ability, cutting cost is low, but there are large cutting distortion, cutting accuracy is not high, but the cutting speed is low, cutting warm-up time, long piercing time, it is difficult to adapt to fully automated The need for operation. Its application is mainly limited to carbon steel, large thickness plate cutting, in the middle, thin carbon steel sheet cutting will be gradually replaced by plasma cutting.

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

CNC laser cutting machine has the advantages of fast cutting speed and high precision. The laser cutting machine is expensive and cutting cost is high. At present, it is only suitable for occasions where thin plate cutting and high precision are required.

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

Other CNC cutting machine: including CNC pipe cutting machine, CNC steel cutting machine, CNC groove cutting machine, CNC woodworking cutting machine, these special cutting equipment is mainly used in a variety of special profiles to CNC cutting, the current market, there are not many manufacturers.

Third, the development trend of CNC cutting machine

With the development of modern machinery processing industry, the requirements for the quality and precision of cutting have been continuously improved, and the requirements for improving production efficiency, reducing production costs, and having a highly intelligent automatic cutting function 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 machine. From the current situation of several general-purpose CNC cutting machines, the functions and performance of the CNC flame cutting machine have been relatively perfect. The limitations of the material cutting (only cutting carbon steel plate), the cutting speed is slow, the production efficiency is low, and its scope of application is gradually In shrinking, there can be no major increase in the market.

Plasma cutting machine has a wide range of cutting (can cut all metal materials), cutting speed, high efficiency, the future direction of development lies in the plasma power technology, CNC system and plasma cutting problems, such as the power of the power can be cut Thicker plates; the refinement and improvement of fine plasma technology can improve the cutting speed, cutting surface quality and cutting accuracy; the perfection and improvement of numerical control system to adapt to plasma cutting can effectively improve work efficiency and cutting quality.

Laser cutting machine has the advantages of high cutting speed, precision and cutting quality. Laser cutting technology has always been a high technology that the country mainly supports and promotes. In particular, the government emphasizes that it is necessary to revitalize the manufacturing industry, which brings development opportunities for the application of laser cutting technology. In the formulation of the medium and long-term development plan, the government has also designated laser cutting as a key supporting technology because it involves national security, national defense construction, industrialization of high and new technology, and development of advanced science and technology, which has brought laser cutting to a very high level. The degree of emphasis will also bring great business opportunities to the manufacture and upgrade of laser cutting machines. In previous years, most of the domestic laser cutting machines were imported products, and the domestic products accounted for a very small share. With the gradual deep understanding and exemplary adoption of laser cutting technology, the company has driven domestic companies to develop and produce laser cutting machines.

2, the development of special CNC cutting machine. The CNC pipe cutting machine is suitable for cutting the normal, oblique and eccentric cross-phase holes, square holes and elliptical holes on various pipes, and can cut the intersecting line 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. CNC groove cutting machine is one of the relatively high-end products in the line. The rotary groove cutting function of this type of equipment can meet different requirements of different angles of groove opening in the welding process. With the development of China's shipbuilding industry, the shipyard has taken the lead in the introduction and use of CNC plasma cutting machines. With the development of technology, domestic and foreign shipyards are now equipped with CNC plasma cutting machines with a rotary groove cutting function to meet the requirements for the construction of high-tech and high-value-added ships.
