Engraving machine lubrication is to prevent and reduce component wear and prolong its service life and replacement cycles, reduce accidents and engraving machine failure, to ensure normal production, to improve the economic efficiency of enterprises of great significance. Commonly used stone engraving machine, woodworking engraving machine, advertising engraving machine, engraving machine foam under the long-term work, screw, guide, there will be quite a lot of internal bearing dust and impurities entering, causing screw, bearing rotation resistance, eventually leading to engraving speed slightly faster loss occurs the phenomenon of dislocation. Therefore engraving machine in daily use should pay attention to the maintenance and cleaning engraving machine parts lubricated.
