Different materials of the tool engraving materials of different hardness will have a suitable lower cutting depth, which is a reasonable cutting amount. It can make reasonable use of the cutting performance of the stone engraving machine tool, and obtain higher quality under the premise of ensuring the processing quality. A cutting amount of productivity and low processing cost.
The unit cutting amount is equal to the cutting (knife) depth * cutting width (path spacing) * the cutting speed. The cutting process is generally divided into roughing, semi-finishing and finishing. When roughing, remove all the margin as much as possible. When large, the amount of cutting should be determined by considering the power of the stone engraving machine and the strength of the tool to avoid causing large vibrations, and the tool is broken by a large impact. When finishing, the limitation of machining accuracy and surface roughness is mainly considered. When required, it is necessary to consider adding a semi-finishing process to make the pre-finishing allowance uniform, so as to achieve a satisfactory effect. To determine the amount of cutting, the power and tool strength of the stone engraving machine and the rigidity of the process system should be considered.
For alloy tools, the depth of the engraving marble and bluestone can be controlled to about one millimeter each time, and the diamond cutter can be adjusted to more than 2 mm. The material with higher hardness grade such as granite is engraved, the lower knife speed and the lower knife depth. Don't be too deep, you can lower the knife and increase the processing speed setting, so the efficiency will not be very low.
Stone carving is a relatively fine and professional technique, and the depth of the lower knife is the premise to ensure the quality of the whole sculpture, so we must grasp this degree.
