How to correctly buy engraving tools, what characteristics do we need to pay attention to?

1, high hardness and wear resistance
Hardness is the basic characteristics of the tool material should have, the tool to cut the material from the workpiece, its hardness must be greater than the hardness of the workpiece material. The hardness of tool material is generally above 60HRC. Wear resistance is the ability of the material to resist wear, under normal circumstances, the higher the hardness of the tool material, the better the wear resistance, the finer the grain of the material, the more uniform the distribution, the higher the wear resistance.

2, sufficient strength and toughness
In order to make the tool under great pressure, as well as in the cutting process of shock and vibration under the conditions of work without collapsing and breaking, the tool material must have sufficient strength and toughness.

3, high heat resistance
It refers to the performance of tool materials to maintain hardness, wear resistance, strength and toughness at high temperatures. The higher the high temperature hardness of the tool material, the better the cutting performance of the tool, the higher the allowable cutting speed; In addition to high temperature hardness, tool materials should also have the ability to resist oxidation at high temperatures and good adhesion and diffusion resistance.

4, good process performance
In order to facilitate manufacturing, the tool material is required to have good process properties.

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

6, the predictability of cutting performance
With the development of machining automation, cutting properties such as tool wear and tool durability are required to have good predictability.
Because the hardness of the carved material is different, the material structure and other properties are different, the customer chooses the tool, as far as possible according to its specific hardness and processing technology to choose, so that not only can better save the processing cost, but also can achieve better engraving effect.

Single-slot spiral cutter (cemented carbide)

Main function: 2D cutting

Applicable materials: acrylic, PVC, MDF

Features: combined with the advantages of single groove design, strong cutting force and smooth chip removal, while spiral cutting ensures the smoothness of the cutting surface. It has excellent working efficiency in batch processing of PVC and MDF.

3D carving knife (cemented carbide)

28 2月 2023 | 没有评论 | posted by admin | in Article

Main functions: 3D corner cleaning and chamfering

Applicable material: organic, PVC. Can also be used for: density board, medium hard wood

Notes: whether the engraving is positive or negative, the engraving plane must be kept flat; It is very important to select the appropriate blade width for 3D clear angle carving. It is recommended that the blade width of the small-format engraving machine should not exceed 22MM. The large-format engraving machine can speed up the carving speed by using the appropriate blade width.
