Lawn and vegetation may have different Angle trimming requirements when pruning, such as horizontal pruning, diagonal pruning or vertical trimming, which requires the use of arc blade hedge trimmer, and blade is an indispensable part of arc blade hedge trimmer. Choosing the right arc blade hedge trimmer can greatly improve the efficiency of lawn and paper cup trimming. What parameters should be paid attention to when purchasing blades?

1, consider the material. The quality of the blade depends on the choice of material. According to the different blade material, its service life, processing efficiency, surface quality and other aspects also have significant differences. Commonly used blade materials are high-speed steel, carbide, ceramic cutting tools, etc.

Among them, the high-speed steel blade is a commonly used economic blade, which is suitable for the processing of general steel, but the processing effect of wear-resistant materials is poor. Carbide blades are the choice of high strength and high hardness, widely used in the processing of steel and cast iron, but the cost is relatively high. Ceramic tool is a new material, strength and hardness are relatively high, can cope with high hardness processing.

2, consider the processing material. Different processing materials have different requirements for arc blade hedge trimmer blades. Generally speaking, steel processing requires large cutting force, but the wear is slow, and the cutting speed is relatively fast; For the processing of wear-resistant materials, the cutting force is required to be small, but the wear resistance needs to be improved to prevent the blade from wearing too quickly, resulting in reduced processing efficiency.

3. Consider the geometry of the blade. The geometrical shape of the blade has a significant effect on its machining effect. Generally speaking, the tool milling diameter is larger, the processing surface is rough, and the tool milling diameter is smaller, the processing surface is more smooth and flat.

When selecting the blade geometry, it is necessary to take into account the shape, material height, structure and other characteristics of the material to be processed in order to achieve high efficiency, low abrasion resistance and good cutting quality.

4. Note the tool geometry parameters of the arc blade hedge trimmer blade. The geometric parameters of the tool include the edge Angle, the edge Angle and the edge intersection Angle. The tool edge Angle depends on the material to be processed, the general edge Angle to make the tool in cutting to maintain a greater strength, and the edge cutting is required to have a better feed effect, remove the film of the cutting part and wet grind a layer of basically flat surface.

The Angle of the edge intersection Angle is usually between 10° and 20°, and the small edge intersection Angle can reduce the cutting force, reduce the heat and film thickness; The large edge intersection Angle can improve the hardness of the tool, so that its life is long and the machining result is better. The choice of edge Angle should be based on the material of the object to be processed, but also consider the cutting force and thermal resistance.

Choosing the right arc blade hedge trimmer takes into account a number of factors, such as material, machining material, geometry and tool geometry parameters. Sometimes, the conventional size specifications of the blade on the market may not meet the actual use needs, which requires customization to the blade manufacturer.
