Engraving machine surface uneven how to solve

Engraving machine uneven leads to carve out what shades, lead to some deep some shallow cut cut plate is not transparent, so when this happens must screen, see whether that part out of the question. Engraving machine surface uneven? 1, carving machine if mesa is uneven, so find a factory can only be solved but 2 engraving machine surface is flat plate gravamen either replacing plate, plate milling flat either. Engraving machine surface uneven how to prevent? 1 chance carving, directly on the engraving machines, the cutting tool is always down to the table so that the knife, not damage the mesa. 2, the path of concrete operating mode is calculated, don't set up according to the material thickness of the 'depth' carved directly set to '0 mm before production G code files, can set the tool' depth 'to: carry knives height + cutting material thickness. 3, for example, the cutting tool on the tool material appearance height 8 mm thickness of the material by 10 mm then tool 'distance' value for: 8 + 10 = 18 mm left in addition to set the cutting tool on the carving machines, other operations are unchanged through the above introduction, solve the engraving machine fixed way below, engraving machines placed the cause of the plate, the machine surface uneven solution and prevention programs. Engraving machine fixed plate in one of two ways: one is the vacuum adsorption, is another kind of fixture is fixed, and a pneumatic roller is fixed, etc. Engraving machine: why do you want to place on the surface of plate? Engraving machine generally pad on the surface of a sheet, have a plenty of density board, also have PVC board, etc. Engraving machine is placed on the surface of plate is to protect the table from being damaged. Once the rugged, mesa will affect plate fixed fastness degree, may also affect the workpiece machining accuracy. Mesa and equipment as a whole together once damaged, replace the mesa of time and cost is not small, so I need a plate, even if the plate gravamen, only need to directly change the plate for replacement plate the time and cost.
