What are the precautions in the operation of the advertising engraving machine?

1. In the actual processing, the relationship between machining effect and machining efficiency should be fully considered, and the coarse knife, fine knife and three-dimensional engraving can be flexibly applied. Large-area graphic area engraving uses large tools for processing, and small-area graphic areas or The effect of the small tool should be used for fine machining, and the setting of the overlap rate of the tool is also important.

2. Select the processing method according to the processing result requirements-----two-dimensional engraving, three-dimensional engraving or cutting. If pattern engraving is performed, two-dimensional or three-dimensional engraving is selected, and the generated processing path is the engraving path. If you are cutting and machining the wall surface of the sand table model, select "Cutting Word" and the generated path is the cutting path.

3. According to the requirements of processing effect, the path generation method is selected. The two-dimensional path is suitable for plane engraving. The processing effect does not have a strong three-dimensional effect, and the processing fineness is inversely proportional to the processing depth. The three-dimensional path has a "clear angle" engraving action, the processing effect has a strong three-dimensional effect, the processing pattern is fine, the processing fineness is directly related to the fineness of the pattern and the accuracy of the tool parameters, and the processing depth only affects the three-dimensional and does not affect the fineness of the processing. The degree, the greater the processing depth, the stronger the stereoscopic effect.

4. According to the fineness of processing and the texture of the material, choose the engraving processing path form----horizontal milling bottom, vertical milling bottom, forward 45 degree milling bottom, reverse 45 degree milling bottom. These engraving paths produce high processing precision. The processing surface is smooth. The circular path has a fast processing speed and high efficiency, but the processing effect is inferior to others.

5. Engraving tool selection, pay attention to the influence of cutting edge angle and blade width on machining accuracy and progress. If the cutting edge angle and blade width are large, the machining speed is fast, but the machining pattern is not fine, the cutting edge angle and blade width are Small processing speed is slow, but the graphics are fine and the durability of the tool is relatively poor.

How familiar is the importance of advertising engraving machines?

The correct use of CNC advertising engraving machine is the key to reduce the failure of advertising engraving machine and prolong its service life. It plays an important role in preventive maintenance. According to statistics, one-third of the faults are caused by humans, and general maintenance (such as oiling, cleaning, inspection, etc.) is carried out by the operator. The solution is to emphasize the awareness of equipment management, use and maintenance, and strengthen Business, technical training, improve the quality of operators, so that they can master the performance of CNC machine tools as soon as possible, strictly enforce equipment operating procedures and maintenance procedures to ensure that equipment operates in a reasonable working state.
