Analysis of water jet cutter's characteristic and abrasive

Pressure on the depth of cutting:
Determined pressure and velocity of the water jet erosion energy, and its size is proportional to the water jet cutting ability. When high pressure, the machining tank side area, high efficiency, removing less; contrary, low efficiency, better quality; processing tank is too wide, it will result in waste of material. Different types and thickness of material being cut, the pressure corresponds to a certain limit, the case where only the water pressure exceeds the pressure value can be effectively cut. Often considered the best pressure is about 2.5 times the limit pressure value, then the pressure and the depth of cut is linear.

Nozzle traverse speed, but also have a greater influence on the surface quality of the processed material. With the increase of the traverse speed, the cutting capacity per unit area decreased, increasing the surface roughness of the material, particularly when the traverse speed reaches a critical value, the machined surface roughness increased dramatically. The size of its critical value and the abrasive nature of the greater impact.

Application of laser cutting machine and waterjet metal cutting machine

Metal cutting machine as a new tool is currently applied to a variety of more mature industries. So in the end is how the use of laser cutting or waterjet cutting machine, and laser cutting is good or bad and how to distinguish it? First, in the form of energy of laser light focused into a beam of high density, the beam is transmitted to the work surface, to generate enough heat to melt the material, combined with the high pressure gas coaxial with the beam interval removing molten metal directly, to achieve the purpose of the cutting This description is essentially the difference between laser cutting machine with mechanical processing. It is the use of laser light from the laser beam emitted from the generator, the external circuit system, a high power density focused laser beam irradiation conditions, the laser heat is absorbed by the material of the workpiece, a sharp rise in temperature of the workpiece, after reaching the boiling point, the material begins to vaporize and form holes, moving the light beam with the relative positions of the workpiece, the material eventually forming the slit. Process parameters (cutting speed, laser power, gas pressure, etc.) and when kerf trajectory by CNC control system, slag slotted auxiliary gas at a certain pressure is blowing. Generally, laser cutting quality can be measured by the following six criteria. 1. Cutting surface roughness Rz 2. Incision dross size 3. Trimming squareness and inclination u 4. Cutting edge garden diagonal size r 5. Streak after dragging quantity n 6.

Woodworking engraving machine noise problem

Woodworking engraving machine noise problem

CNC engraving machine abnormal noise may be certain moving parts loose or is damaged, we can be handled by two methods. First, check the screw, rod and bearing exercise, such as a relatively large number of components. If you do not find any problems, you can check the cnc router lubrication system is not in good condition; still mechanical configuration is correct. Sometimes the machine may be in the absence of problems after the company confirmed with the guidance of a technician, he was secretly re-release too, so there will be a condition of abnormal noise.

These are just some of the more common approach noise problems, because many types of engraving machines, machine parts themselves are very different, so the engraving cnc machine is noisy solutions are also different. For Wood cnc engraving machine businesses, working to learn more about the properties and characteristics of engraving cnc router machine use, the device will be able to grasp the anomalies appearing in use.
