Who can talk about the choice and use of tools on the engraving machine? They are used to carve bluestone, marble and wood. I hope they are not used for advertising.

Classification of common tools for stone carving machine:

Various carving knives will be used in stone carving. The carving net collects a large number of knives commonly used in stone carving machines for users' reference:

1. Standard angle alloy knife: this knife is made of high-performance alloy material, with double-edged design, standard angle, good lettering and fine relief effect, and is generally used for carving bluestone and marble. Can be customized and polished into a flat-bottomed sharp knife.

2. Commonly used knife-type alloy knife: This knife is made of high-performance alloy material, with double-edge design, good sharpness and high cost performance, which is convenient for manual regrinding. Disadvantages: The angle of this knife is not standard and it is not suitable for relief. Generally used for carving bluestone and marble.

3. Integral alloy triangular knife: this knife adopts ultra-fine wear-resistant alloy, and its wear resistance is much higher than other triangular knives on the market. Angle standard, good lettering effect! Recommended for users of general tool grinder.

4. Diamond four-edged knife: This knife is generally used to carve granite small characters or lines. The advantage is long service life, but the disadvantage is relatively poor sharpness and shallow carving depth.

5. Sintered diamond grinding head cutter: This cutter is generally used for milling the bottom of granite. Because the cutter head is made of multi-layer diamond sintered, the service life is very long! The disadvantage is that the sharpness is not high and the cutter head will be deformed. Therefore, in order to get higher output and carving effect, it is not recommended to carve marble, bluestone and other materials. This kind of knife can be selected when making granite and other difficult-to-process stone materials.

6. Melting drill grinding knife: This knife is made of melting drill technology! It has the characteristics of good sharpness, high carving efficiency, no deformation of the cutter head and high carving accuracy. When carving marble, bluestone, sandstone and other materials, it is often used as the first choice tool for efficient relief and a sharp weapon for carving Chinese characters.

7.PCD polycrystalline diamond knife: this knife adopts imported polycrystalline diamond blade, and adopts vacuum welding technology, so the blade will not be damaged or fall off. Micro-grinding technology maximizes the sharpness and strength of the blade. Generally used to carve granite fine print. Good hardness, long service life and good carving effect. Pay attention to cutting flexibly when using, and don't use too much force when cutting!

Stone carving machine tool selection guide:

The knives of stone carving machines in the market are uneven, and the prices vary greatly. I hope this article can provide some help and suggestions for the majority of stone carving machine users in choosing knives.

1. Pay attention to the high hardness and wear resistance of stone carving tools;

Hardness is the basic characteristic of stone materials. The hardness of the tool must be greater than the hardness of the workpiece material in order to cut the material from the workpiece. The hardness of tool materials is generally above 60HRC. Wear resistance is the ability of materials to resist wear. Generally speaking, the higher the hardness of the tool material, the better the wear resistance, the finer and more uniform the grain distribution of the material, and the higher the wear resistance.

2. Pay attention to the strength and toughness of stone tools:

In order to make the tool work under the conditions of great pressure, impact and vibration during cutting without edge collapse and fracture, the tool material must have sufficient strength and toughness.

3. High heat resistance of stone carving tools:

Refers to the performance of tool materials to maintain hardness, wear resistance, strength and toughness at high temperature. The higher the hardness of the tool material at high temperature, the better the cutting performance of the tool and the higher the allowable cutting speed. In addition to high-temperature hardness, tool materials should also have high-temperature oxidation resistance and good anti-adhesion and anti-diffusion ability.

4. The economy of cutting tools:

Economy is one of the important indexes of tool materials. Although some tool materials are expensive, the cost allocated to each part is not necessarily high because of its long life.

5. Predictability of tool technical performance and cutting performance:

In order to facilitate manufacturing, tool materials are required to have good technological properties. With the development of machining automation, it is required that the cutting performance such as tool wear and tool durability has good predictability.
