Sharpening an ax with a grinder: description of the process, sharpening angle

The condition of any tool determines the quality and effectiveness of its use. Blade sharpness is the main indicator that affects normal operation ax. Regular and correct sharpening is important to ensure it. There are various ways to edit the main working element of the tool - using an electric sharpener, sandpaper, an abrasive bar, a grinder. We will understand the nuances of using the latter at home.

Sharpening an ax with a grinder: the right steps

To ensure the safety and efficiency of the process, you should:

1. Take care of the presence of a special disk designed for sharpening - the use of a cutting wheel is prohibited.
2. To fix the grinding wheel - it is necessary to remove the casing, use special fasteners for tightening.
3. Place the angle grinder in a vise and fasten securely.
4. To process the surfaces of the blade, alternately passing through different planes.

Attention! Before starting work, you should protect yourself by using personal protective equipment.

A grinder for processing working elements of axes is used if the latter are made of high-quality steel. The disadvantage of the method is that it is not possible to adjust the rotation speed. This leads to edge overheating and changes in material properties.

If you neglect the fixation of the angle grinder, the risk of beating the circle will increase, and the angle will not be maintained. The blade will be damaged, and the thickness in different areas will be different.

What to consider so that sharpening is correct

The optimal way to edit the working part depends on several parameters. In particular, from the scope. Sharpening can be:

• straight - suitable for rough work, which include chopping firewood, cutting trees;
• oval - ideal for precise manipulations, called universal because it is suitable for many types of operation;
• shaving - for a highly specialized tool.

The sharpness of the working part depends on two main indicators: the angle of sharpening and the width of the chamfers.

Corner Options

Before starting processing, it is worth making a sample of the correct angle. For this you need:

• take a piece of hard material and apply markings;
• cut the desired shape using scissors for metal;
• attach it to the edge, mark the areas for editing on the blade.

According to GOST, the sharpening angle should be different if the tool is used for different types of work - carpentry, construction. With this in mind, the values ​​​​should be 45 ° or up to 30 °, respectively.

The given parameters are not considered rigid and may change.

The sharpness directly depends on the angle of sharpening - the smaller it is, the sharper it is. However, excessive sharpening of the working surface can lead to its rapid blunting. In addition, the tool will get stuck in the wood pulp when chopping wood.

Chamfer width

This parameter represents the distance from the cutting area to the side surface. The life of the tool depends on what its value is, as well as how sharp the blade is.

When the chamfer is worn during operation, a rebound from the surface of the barrel may occur. To edit the working part and ensure efficient use, a double escapement is used. This is a processing method when the first angle is 15 °, and further sharpening is carried out in accordance with the purpose of the tool.

Using a grinder for such work is quite dangerous. You must be careful, take precautions and use personal protective equipment.
