How can we correctly choose the engraving tools of wood engraving machine, what are the characteristics we need to pay attention to? Although the CNC woodworking engraving machine belongs to the category of CNC engraving machine, due to the characteristics of its engraving material and the processing strength, it is destined to have very high requirements for its machine tool construction. The requirements such as machine tool stability, spindle performance and tool performance are very high. . In particular, the engraving tool is a big consumable. The customer must choose the accuracy when selecting 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 choice of woodworking engraving tools, Qingdao Speedmaster CNC engraving machine factory will give a detailed introduction.
1, high hardness and wear resistance
Hardness is the basic characteristic that a tool material should have. The tool must cut the material from the workpiece and its hardness must be greater than the hardness of the workpiece material. The hardness of the 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 and the more uniform the distribution, the higher the wear resistance.
2, sufficient strength and toughness
To allow the tool to withstand high pressures and to withstand impact and vibration during the cutting process without chipping and breaking, the tool material must have sufficient strength and toughness.
3, high heat resistance
Refers to the ability of the tool material 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 cutting speed. In addition to the high temperature hardness, the tool material should have the ability to resist oxidation at high temperatures and good anti-adhesion and anti-diffusion. Ability.
4, good process performance
For ease of manufacture, tool materials are required to have good process properties.
5, economy
Economics is one of the important indicators of tool materials. Some tool materials are expensive, but because of their long life, the cost of each part is not necessarily high.
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 of the materials carved by the wood engraving machine and the different properties of the material structure, the customer chooses the tool according to its specific hardness and processing technology, which not only can save the processing cost, but also achieve better. The engraving effect.
