Development status of cutting machine
Development status of cutting machine：
1, after several decades of development, CNC cutting machine in cutting energy and CNC control system has made considerable progress, cutting energy from a single flame energy cutting development for a variety of energy (flame, plasma, laser, high-pressure water jet) cutting methods; CNC Cutting Machine control system has been from the original simple function,
Complex programming and input methods, low degree of automation to develop a functional, intelligent, graphical, networked control mode, drive system also from the stepper drive, analog servo drive to today's all-digital servo-driven;The main varieties of CNC cutting machine include the following kinds:CNC Flame 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-metallic special cutting equipment, etc.)
2, the characteristics of various types of CNC cutting machine and its application CNC Flame Cutting machine, cutting has a large thickness of carbon steel cutting capacity, cutting costs are lower, but there are large cutting deformation, cutting precision is not high, and cutting speed, cutting preheating time, perforation time is long, more difficult to adapt to the needs of the full automation operation.
Its applications are mainly limited to carbon steel, large thickness plate cutting, in medium and thin carbon steel plate cutting will gradually be replaced by plasma cutting. CNC plasma cutting machine, plasma cutting has a wide range of cutting, can cut all metal sheet, cutting speed, high efficiency, cutting speed up to 10m/min above. The plasma cutting can eliminate the noise, dust, harmful gas and arc pollution, and improve the environment of the working situation effectively.
The use of fine plasma cutting has made cutting quality close to laser cutting level, with high-power plasma cutting technology mature, cutting thickness has exceeded 100mm, widened the CNC plasma cutting machine cutting range.
CNC laser cutting machine, with fast cutting speed, high precision, laser cutting machine expensive, high cutting costs, only suitable for thin plate cutting, high precision requirements of the occasion, CNC high-pressure water jet cutting machine, applicable to any material cutting (metal, non-metallic, composite materials), cutting precision, do not produce thermal deformation, with environmentally-friendly cutting methods.
Its disadvantage lies in the slow cutting speed, low efficiency, 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 are mainly used in a variety of special profiles for CNC cutting, the market on the manufacturers are not many.
