CNC control technology of ultra-high pressure water cutting equipment
The uniqueness of ultra-high pressure water cutting equipment is that the high energy water flow generated by ordinary water after multi-stage pressurization, and then through a very thin ruby nozzle, can cut at a speed of nearly a kilometer per second.From the structural form, there can be many forms, such as two to three CNC axis gantry structure and cantilever structure, this structure is mostly used for cutting plate; five to six CNC axis robot structure, this structure is mostly used for cutting car interior parts and car lining.
Simple ultra-high pressure water cutting equipment has two CNC axles, controlled by CNC XY for CNC movement, and can realize CAD / CAM direct conversion, truly free keyboard input, no picture processing, as long as any complex curve drawn in the CAD, can be directly cut and formed.
Moreover, the cutting accuracy of the ultra-high pressure water cutting equipment is between 0.1mm and 0.25mm, which depends on the accuracy of the machine, the size range of the cutting workpiece and the thickness and material of the cutting workpiece. Generally, the system positioning accuracy of the machine is 0.01mm to 0.03mm.
The abrasive used in the cutting process is quartz sand, garnet, river sand, diamond sand, etc. The particle size of the abrasive is generally 60-80 meters. The higher the hardness of the abrasive, the greater the particle size, the stronger the cutting capacity; and the CNC CNC technology is higher and better efficient than the traditional control technology.
When using CNC CNC technology, it is necessary to use appropriate cutting liquid with the cutting tool. The cutting liquid should be better on water-based cutting liquid with good cooling performance, which can provide cooling effect for ultra-high pressure water cutting equipment and improve the cutting quality.
