After decades of development, CNC cutting machine in the cutting energy and CNC control system has made great progress in two aspects, cutting energy has been developed from a single flame energy cutting for a variety of energy (flame, plasma, laser, high-pressure water jet) cutting; CNC cutting machine control system has been developed from the initial simple functions, complex programming and input methods, the degree of automation to a low degree of development to have a complete function, intelligent, graphical, networked control; drive system from the stepping drive, analogue servo drive to today's all-digital servo drive.

The main varieties of CNC cutting machines include the following:

CNC flame dense cutting machine

CNC plasma cutting machine

CNC Laser Cutting Machine

CNC high pressure water jet cutting machine

Other special cutting equipment (such as CNC pipe cutting machine, CNC profile cutting machine, other non-metal special cutting equipment, etc.)

 

2, the characteristics of each type of CNC cutting machine and its application

CNC flame cutting machine, cutting carbon steel with large thickness cutting ability, cutting costs are lower, but there is a large cutting deformation, cutting accuracy is not high, and the cutting speed is low, cutting preheating time, perforation time is long, it is difficult to adapt to the needs of fully automated operation. Its applications are mainly limited to carbon steel, large thickness plate cutting, in the medium and thin carbon steel plate cutting will gradually be replaced by plasma cutting.

CNC plasma cutting machine, plasma cutting has a wide cutting field, can cut all metal plates, cutting speed, high efficiency, cutting speed up to 10m/min or more. Plasma cutting underwater can eliminate the noise generated during cutting, dust, harmful gases and arc light pollution, effectively improve the workplace 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, cutting thickness of more than 100mm, broadening the cutting range of CNC plasma cutting machine.

CNC laser cutting machine, with fast cutting speed, high precision and other characteristics, laser cutting machine is expensive, high cutting costs, only suitable for thin plate cutting, precision requirements of high occasions.

CNC high-pressure water jet cutting machine, suitable for any material cutting (metal, non-metal, composite materials), high cutting accuracy, does not produce thermal deformation, with environmental protection cutting method. Its disadvantage is that the cutting speed is slow, low efficiency, high cost of cutting.

Other CNC cutting machine: including CNC pipe cutting machine, CNC steel cutting machine, CNC bevel cutting machine, CNC wood cutting machine, these special cutting equipment is mainly used in a variety of special profile CNC cutting, not many manufacturers on the market.
