How to use a glass knife? How to cut glass with a glass knife

Glass knives"Also known as:"Glass pen", glass pens are generally divided into:"wheels"type and"Diamonds"There are two types.

As long as it is used properly,"wheels"The type is better because it is smoother.

Some of the corners crack after a period of use, because your glass is not edging.

Any kind of knife must be familiar with the position of his blade!

For example, the blade of a glass knife is just a little more difficult to master!

After a few exercises, you'll find the blade!

And cut in one go, don't pause in between! Don't repeat the cut! (Scrap blade) and master the appropriate strength!

There are also some tricks: for example, thick glass, you can apply some kerosene at the position to be scratched, so that it is easier to break the fracture will be more neat, but it is still recommended to grind the glass machine to grind the edge, you can grind off some subtle cracks that are not easy to find in the glass fracture, increase the strength of the glass, and also increase the safety factor for people during operation. Nowadays, the general glass knife uses a roller knife edge, if you don't often cut the glass, you can put the knife edge in kerosene and soak it in plastic paper to wrap it in plastic paper to prevent raw embroidery.

The glass is flat, the glass knife edge is pulled from the head to the corner (provided that the strength is even), and finally the pulled opening is the most fulcrum, and both hands are forced. And it was broken in half.

Breaking the glass requires a fulcrum, that is, the straight line you draw with the glass knife, if you do it or not, it is the same strength and skill.

First, lay the glass flat and wipe the area to be marked with a rag! Then use the eldest and second and third fingers like holding a pencil, hold the glass knife and gently aim at the target, to make a knife, and then force the reverse to break it, and the large piece can be shaken!

It's as simple as pressing that head on the glass and you're going to cut it!

The step of using a glass knife to cut glass is as follows:Tools: glass knife, draft survey, water plate.

1. Pinch the glass knife with your thumb and forefinger so that the glass knife is tilted at a 45-degree angle.

2. Cut the glass from top to bottom, in the direction, not in the reverse direction.

3. Use a water gauge and other items as a reference line for fixed sizes.

4. Lean the glass knife against the water plate or draft gauge to cut the glass.

5. From top to bottom, cut in place at one time, without stopping halfway.

6. Press the glass knife with your vertical hand and then cut it hard.

The steps of cutting glass with a glass knife are: first fix the size to be cut with a ruler on the glass that needs to be cut, and press the glass knife at a 45-degree angle with the glass knife in your hand, when the glass to be cut makes a "rustling" sound, and the slit that is cut can be seen on the glass, it proves that the glass has been cut.

1. First of all, we use a ruler to fix the size to be cut on the glass that needs to be cut. Then use a ruler, or something relatively straight, such as a wooden board, as a line when cutting glass.

2. Then hold the glass knife in your hand and press it on the glass at a 45-degree angle, and then press down hard to cut.

3. Note that the cutting head of the slag cutting manuscript cavity in front of the glass knife must be in contact with the glass.

4. When the cut glass makes a "rustling" sound, and the cut slit can be seen on the glass, it proves that the glass has been cut, and you can break it lightly by hand.

5. Before the formal cutting, it is best to find some waste glass, test and operate on it, find the trick, and then cut it officially.

Tools such as broken white steel handles, assorted files, porcelain chips, and sharpened carbide bits can replace glass knives. The tool that replaces the glass knife should be harder than the old glass of Shouyou, with sharp ports, and the ports are not easy to break or smooth and passivate.

Glass knives can be divided into diamond glass knives and alloy roller glass knives, which are indispensable glass cutting tools in the decoration and building materials industries.

A glass knife is a tool that cuts glass, and the part cut by the glass knife is made of diamond or alloy materials that are harder than glass.

Fix the size with a ruler, hold down the ruler, and use a glass knife to draw down the ruler all the way, and feel the sound of someone cutting through the glass skin, which is a successful cut of the glass.

There are several common tools and methods:

The heating wire adheres to the glass surface and heats up. The glass is naturally cracked when heated unevenly. Cotton thread, soaked in kerosene, placed on the glass in the desired shape, lit and quickly thrown into the water.

Start with something hard and scratchable before breaking the glass. The hospital scratches the small grinding wheel of the injection bottle, grit (slightly larger translucent and crackless yellow-white particles in the sand and gravel, beaten into a sharp shape), the alloy head part of the impact drill bit, and the sharp glass piece.

In addition to ordinary glass knives, there are also these tools for cutting glass:

1. Ground carbide cutter bits for lathes;

2 Broken white steel shank with a cutting edge;

3 assorted files;

4 pieces of electric porcelain.

Selection Principles:1The hardness is higher than that of glass, the higher the better.

2.There are sharp ports, and the ports are not easy to break or grind and passivate.

Cutting method: fix the size with a ruler, hold down the ruler, and draw all the way along the ruler, pay attention, use force, and feel the sound of cutting the glass skin. If you feel that the stroke is silent, it is generally that the strength is not there, and you can re-draw it.

As long as I can draw the nicks, I have used tungsten steel to sharpen the tip, and I can use it as well.

It can be sharpened with a super-hard tungsten steel rod (long tungsten steel boring bar).

Many friends may have seen what kind of shape the glass knife is, yes, it is very similar to the ordinary pen we usually use, but do you know how to use the glass knife correctly?

1. How should the glass knife be used?

1. First of all, before using the glass knife, you need to put the glass in a suitable position, you must keep the glass flat, and fix it on one side.

2. Then start to make the position that needs to be cut on the glass, and mark it, and then hold the position of the pen barrel of the glass knife with your hand.

3. Next, place the front end of the glass knife at the starting point.

4. When cutting the glass, the index finger and thumb should hold the top of the front end like a pen, and press down with the index finger to play a certain role in stress, and then slide back to cut the glass.

2. What are the things that need to be paid attention to when using glass knives?

1. First of all, you need to pay attention to the problem of glass placement before using the glass knife, because there is no way to determine the size of the glass you want to cut, so try to ask everyone to put the glass in a relatively flat position, and it is best to lay a layer of carpet below, so that its friction can be increased, then the second is the problem of fixing, it must be fixed, because it is possible that when cutting the glass, the glass and the glass knife form a relatively deep groove, so that the glass can be moved backwards at one time. Then the cut effect may not be very smooth.

2. The second thing to note is that when using the glass knife, remember to use force, and if necessary, you can hold the glass knife with your left hand and right hand at the same time. Because the glass knife drawn out with one hand is cut, the scratch in the middle may not be particularly obvious, so the cut is continuous.

3. In the process of cutting glass, you can control the speed of the glass knife sliding, but you must not stop in the middle to celebrate the game, because once the pause occurs, it is possible to make the unevenness in the middle, so that the cut glass is not particularly straight.

I concluded: cutting glass is not a particularly difficult thing, and most friends can do it, as long as they can control some of the above required matters.

1. Fix the size with a ruler, hold down the ruler, and use a glass knife to draw all the way along the ruler fiber source. Feel the sound of the glass cutting.

2. After drawing the line, put the glass knife under the glass, put the glass on the side of the table, bring gloves, press the palms of the two hands on both sides of the traces, and use force in the palms of both hands at the same time.
