Various Ways To Cut Glass Tube

Various ways to cut glass tube

Cutting of thin glass tubes and rods. When cutting thin glass tubes and rods with a diameter of 5mm-10mm or less, they should first be placed flat on the edge of the table, and then cut with a triangular file, a grinding wheel piece (or a newly broken porcelain bowl piece). The edge is pressed vertically on the glass tube where it is to be cut off, push it forward with force until the file mark reaches 1/3 or 1/4 of the circumference of the tube, pick up the glass tube (rod), and press the thumbs of both hands against the file mark The other fingers hold the glass tube (rod), and pull back with both hands at the same time to break it. Cutting of the thick glass tube. First, file a circle of fine marks with a file at the place to be cut, and use a resistance wire to circle around the fine marks. The intersections of the resistance wires are separated by heat-resistant insulating materials (or leave a small gap of 1mm-2mm). The resistance wire can be made by taking a section of the 150W electric furnace wire, heating and straightening. The resistance wire can be adjusted by a voltage regulator or a low-voltage power supply. Power supply at a very low voltage. Wait for about a minute for the resistance wire to be red hot. Drop a drop of cold water on the fine mark, and at the same time power off, the glass tube will be disconnected along the fine mark. The broken glass tube mouth is very sharp and easy to be scratched skin, so after the glass is broken, it needs to be treated. The first method is to burn it on an alcohol lamp; the second is to smooth it on a fine emery cloth or a grindstone. Second, various methods of cutting glass Method 1: use Gasoline cutting, you dip the cotton thread with gasoline, straighten it and place it on the glass track you want to cut and ignite. The glass will crack along this line due to uneven force. If the glass is too thick, it may not be successful.
