How can we correctly choose the carving tool for woodworking engraving machine, what are the characteristics we need to pay attention to? Although CNC woodworking engraving machines belong to the category of CNC engraving machines, due to the characteristics of the engraving material and processing strength, it is destined to have very high requirements for the structure of the machine tool, such as the stability of the machine tool, the performance of the spindle and the performance of the cutting tool. . Especially the engraving tool is a big consumable. Customers must choose the right tool when choosing the tool, otherwise it will not only affect the engraving effect, but also greatly affect the processing quality. In order to let customers know more about the selection method of woodworking engraving machine tools, here is a detailed introduction.
1. High hardness and wear resistance:
Hardness is the basic characteristic that the tool material should have. To cut the material from the workpiece, the hardness of the tool must be greater than that of the workpiece material. The hardness of the tool material is generally above 60HRC. Wear resistance is the ability of a material to resist wear. In general, the higher the hardness of the tool material, the better the wear resistance, and the finer and more evenly distributed the material grains, the higher the wear resistance.
2. Sufficient strength and toughness:
In order for the tool to work without chipping and breaking under the conditions of high pressure, shock and vibration during the cutting process, the material of the tool must have sufficient strength and toughness.
3. High heat resistance:
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 and the higher the allowable cutting speed; in addition to the high-temperature hardness, the tool material should also have the ability to resist oxidation at high temperatures and good anti-bonding and anti-diffusion Ability.
4. Good process performance:
In order to facilitate manufacturing, the tool material is required to have good process performance.
5. Economy:
Economy is one of the important indicators of tool materials. Although some tool materials are expensive, the cost allocated to each part is not necessarily high because of its long life.
6. Predictability of cutting performance
With the development of machining automation, cutting performance such as tool wear and tool durability is required to have good predictability.
Due to the different hardness and structure of materials engraved by woodworking engraving machines, when customers choose knives, they should try to choose according to their specific hardness and processing technology. This will not only save processing costs better, but also achieve better quality. engraving effect.
