Some of us may remember how, when we were too young to understand better, we dipped a piece of string into kerosene, wrapped it around a bottle, and lit the string; we hoped the bottle would break along the strip. The bottle wouldn't break, but it would break in six different directions! A variation of this technique involves wrapping a heated cord around the bottle and opening the juice. The result is usually still a disaster! Now, I found some information about the history of bottle cutting machines for you and I hope it will help you.
This passage is going to talk about the followings of the bottle trimming machine:
1) The history of the bottle cutting machine
2) Principles of bottle cutting machine
Around the late 50's and early 60's, certain trendy restaurants began using water glasses made from wine bottles. The method used to cut bottles at this time was a saw with a fast rotating water-cooled industrial cutting blade.
In the late 60's and early 70's, bottle cutting kits began to appear on the market. This time the method was more practical and cheaper. Basically, a line was etched or scribed in the desired location around the bottle; next, a technique utilized a striking tool that was inserted into the bottle and struck the glass along the indented line.
The tapping method has its uses; this method can be used to split the glass ring. However, this method has several disadvantages: the break point is not always clean, and the tapper is difficult to manipulate to get consistent results!
Therefore, in the end, the hot/cold method was found to be the easiest and cleanest way to cut bottles. Unlike the early catastrophic results with kerosene-soaked ropes or electrical components, the heat is controlled and subsequent cracks develop in a very smooth manner along a specified direction (along the scribe line). The disadvantage of this heating method is that if too much heat is applied, it can lead to fine line cracks along the scribe line; but with practice enthusiasts will find this is not common.

However, before the glass can be heated to form a crack, it must be scratched along its surface. The basic requirement for an etching tool is to create a continuous line along the surface of the glass. To do this, two basic characteristics must be met: 1) the cutting wheel must always be perpendicular to the glass and parallel to the direction of motion for proper tracking; 2) a guide is required to keep the etch straight.
This is the basic principle of the bottle cutting machine.
