Generally, the tools used in woodworking engraving machines are roughly classified into the following types: ball-end knives, sharp knives, scribing knives, full-circle knives, semi-circular knives, and the like. As a part of the engraving machine that directly contacts the workpiece, the tool has a very important influence on the quality of the engraving machine. Tool factors that affect engraving include tool data, geometry, and grinding techniques.
1 ball head knives generally have diameters of Ф6Ф8Ф10Ф12, etc. The key factor for the grinding of woodworking engraving tools is the number of finishing grinding wheels. The grinding wheel with a high mesh number can be used to grind a finer cutting edge. The diameters are selected according to the different processing technology.
2 sharp knives generally have a small diameter, suitable for some woodworking engraving machine finishing, Ф3Ф6
3 scribing knives are also called woodworking engraving machines called lace knives. Generally, wooden knives are usually used for processing wooden doors.
4 full round and semicircular knives are called R road knives.
The tool information used in the woodworking engraving machine is cemented carbide data, a powder alloy, and the performance index that determines the performance of the data is the average diameter of the powder. The smaller the diameter, the more wear-resistant the tool and the higher the durability of the tool.
The sharpness of the tool mainly affects the cutting force. The sharper the tool, the smaller the cutting force, the smoother the machining, the higher the surface quality, but the lower the durability of the tool. Therefore, different sharpness should be chosen when processing different materials. When processing soft and sticky materials, the tool needs to be sharper. When the hardness of the processing data is large, the sharpness should be reduced and the durability of the tool should be improved. But it should not be too blunt, otherwise the cutting force will be too large, affecting the processing.
Can effectively improve the durability of the tool. Grinding wheels with a high mesh number can grind a smoother flank and improve the appearance of the cut.
