If at least once you had to work with an angle grinder, then you should be aware of its shortcomings. One of the main ones is not so high precision cutting of samples, if you work manually. The process of this problem can be complicated, which is especially important if it is necessary to obtain several elements with the same parameters.
Given the kickback and vibration, stationary installation is more convenient. However, the acquisition of an industrial production machine cannot be justified in the domestic environment. The simplest model will cost 22,500 rubles.
Solution
However, such devices have some drawbacks that may suggest that it is easier to make a cutting machine using a grinder and a bed. Factory models of such machines are limited in capabilities. For example, the model discussed above can cut only a 100 mm pipe. But in everyday life, quite often you have to work with samples of a more impressive cross section. In addition, everyone has their own needs, a certain model is not able to satisfy them in full.
Factory equipment can be redone, but this is usually accompanied by financial investments. Sometimes it is completely irrational or impossible to carry out such work. This applies to devices that are made of alloys that are difficult to process. Today, home craftsmen often try to make a cutting machine from a Bulgarian with their own hands. You can use one of several methods to solve such a problem. Having examined them, you can come up with your own design.
Recommendations for the manufacture of a cutting machine
Before you make a detachable machine from a grinder with your own hands, you must prepare the components, which will be the angle grinder and the pipe, which acts as a frame and handle. The grinder should be fixed on it using a metal plate. To complete this workpiece, you should use a thick piece of iron, it will take about half an hour to carry out such work.
The metal sample will go to the support, a corner should be welded to this item. The end of the lever is mounted on the axis, while the return stroke will be provided by the spring. If you make a cutting machine from a grinder with your own hands using this technology, then you can get equipment with a small weight, which can be installed almost anywhere. In addition, the assembly will not be accompanied by costs, because all the necessary elements can be found in the economy.
The second embodiment of the machine
Making a cutting machine from a grinder according to this technique will be somewhat more difficult, but the tool will provide higher precision cutting of the material. To carry out the work, you need to make:
- Desktop;
- frame construction;
- a ruler.
The table frame is welded from a corner and a channel. Sheet metal can be used as a table top, however, in some cases, the following materials are used:
The decision will depend on for what purpose you plan to use the equipment, as well as what blanks you will work with. When a detachable machine is made from a Bulgarian with its own hands according to this technology, it is necessary to carry out another frame structure, one of the parts of which will be stationary and act as a support.
One part has to be installed on the countertop and fixed with welding or bolts. The second design is connected to the first hinges. An angle grinder is installed on it , the position of which can be changed manually. In order to return the device to its original position, springs should be installed.
If you are going to make a cutting machine from a grinder with your own hands, then you will also need to complete the line. With it, you can set the dimensions of the samples. For this, a tube or piece of iron with marks and a moving marker is usually used.
What is important to consider
Today, there are a huge number of machine models. In some, the angle grinder is located under the countertop, in others it is placed above the surface. If it comes to safety, then a do-it-yourself cutting machine from a grinder, the drawings of which you can prepare yourself, it is best to install it from above, this option will be more reliable.
A cut is made along the line of abutment of the disc of the angle grinder to the countertop. If you have knowledge of electrical engineering, then it is recommended to turn it on through a magnetic starter, in which case the button is combined with the pedal. Even if the operator’s hands are busy, he can stop the car at any time with his foot.
When a do-it-yourself cutting machine is made from a grinder, it is important to consider the drawings. Quite often, they allow you to avoid mistakes. It is important to remember the safety requirements. Once the assembly of the machine has been completed, it should be driven, which will make sure that there is no runout of the disk. It must not touch the protective cover.
An alternative embodiment of the pendulum type machine
Creating a cutting machine for metal with your own hands, you may prefer its pendulum variety. At the first stage, profile pipes should be used for this, which will be used for the manufacture of the pendulum and the frame. The metal profile is usually used for cantilever fastening, it is necessary to supplement it with a steel bar and a metal tire.
If it is assumed that the machine has a supporting platform, 5 mm sheet steel should be cut to size. To the lever, which has the form of a section of a profile pipe, it is necessary to strengthen the transverse shaft by welding. In this case, ensure perpendicularity of fastening.
Conclusion
When making a cutting machine for metal with your own hands, you must make a bracket, and make holes for installing bolts in its sides. With their help, the gear housing of the main equipment is fixed. From the bar, you need to perform a clamp and a clamping bar. The latter will take the form of a plate whose length is greater than the width of the clamp by 20 mm.
