It is a kind of engraving machine CNC machine tool. Metal laser engraving machine can be of metal or non-metal plate and pipe non-contact cutting and boring, especially suitable for stainless steel, iron, silicon, ceramics, titanium alloy, epoxy, A3 steel, diamond materials of laser cutting processing. The device is stable and reliable operation, good processing quality, high efficiency, simple operation and convenient maintenance. That is the use of small engraving machine CNC milling machine tool, high power and high speed spindle motor. Foreign countries, and there is no concept of engraving machine, mold processing they are dominated by milling machining center (computer gongs), but machining center has its shortcomings, especially in small tool to process small mold appeared to be inadequate, and the cost is very high. The beginning concept only CNC engraving machine, engraving machine carving, if relatively large workpiece hardness will appeared to be inadequate. Have carved machine can be said to fill the gap between the two. The machine can also be milling, carving, is a kind of high efficient and high precision NC machine tool. Engraving machine: can the precise carving, or milling, engraving machine based on increased spindle servo motor power, bed capacity, while maintaining the spindle speed, more important is precision is very high. The carving machine to multi beam Shiju. For the completion of small carved machine milling, machining small mold, suitable for processing copper and graphite. NC carving machine for small milling, processing equipment or soft metal. Machine tool is divided into two parts, moving parts and moving parts: table, skateboarding, cross children as part of the mobile and the bed, column for non moving part. Non moving part steel requirements of mobile part of steel to a flexible under the premise, as far as possible some light while maintaining certain steel. Advantages: processing can be relatively small, high precision machining. For soft metal for high speed machining; disadvantages: as the steel of it is not possible for heavy cutting. CNC system requirements of high speed engraving machine, spindle speed is about 3000~30000RPM. Milling machines are usually thought Cimatron tool path to be a little better, the new version of the software fully elegant to the uniformity of the cutting tool in the moment, especially the knife into the work out of the moment of speed and smooth, and the inflection point follow difference algorithm followingError, make the results and graphic design more stick into. Part of the CAD just uses a lot of intuitive 3D solid modeling such as SolidWorks by IGS into CAM software for processing.
