Water knife cutting glass belongs to cold cutting, water knife can cut arc, sharp corner, can cut out any complex pattern on the plane, and full numerical control, high efficiency, good quality, generally used in process glass.

And cutting without opening, you can also punch. The section is ideal. When the water knife is used to cut glass, the normal pressure of the water knife is 260-280mpa. If the pressure is too high, the water cutting machine manufacturer will cut the glass and produce edge collapse.

The selection of cutting speed should be set according to the cutting surface. Generally, the vertical cutting surface is the speed. In the glass cutting process, the cutting edge should not be the edge of the glass, try to feed from the outside of the glass.

After smoothing, cut to the edge of the glass, if not, then throw it down by manual edging machine.

When we use water jet to cut holes or other shapes, the size of glass is not large, but we can only cut one piece of glass at a time. The time spent on the upper and lower pieces is much more than the actual processing time. What can we do to process multiple pieces at one time and shorten the auxiliary time? This problem can be solved as follows:

If the glass is not big enough, you can make 2-4 positions on your worktable when making CAD drawings, that is, your machine is 4000x2000, and your product only needs 1500x1000 space, then you can make 4 processing drawings at a time, and put 4 pieces of glass at the same time (the glass corner is unified, and the size is the same), and make the block to facilitate the glass alignment (turn off the electronic eye alignment), In this way, when the machine processes the back glass, you can move up and down, but there is a back safety operation, and a cable emergency stop switch is installed on the table. When the water knife cuts, there may be edge collapse. 1. There may be edge collapse in the middle of the original piece. 2. There may be beveling on the four sides of the original piece, which affects the diagonal of the product.

resolvent:

1. Get the product open size read by the device correctly.

2. Reduce the angle of water jet cutting head.

3. When breaking a piece, first break the crack, then use a hand knife to divide the part into small pieces, gradually break it off, and don't try to take off the complete leftover material. That doesn't mean much.

4. When breaking the edge, the force should be downward and outward (relative to the knife mark).
