Cleaning and maintenance

     The cutting tools should be cleaned in time after each use. Use dedicated tool cleaning tools, such as soft brushes and cleaning solvents, to remove chips, oil stains and dust from the surface of the tools. For example, for the paper fibers remaining after cutting the paper, they can be gently brushed off with a soft-bristled brush. For the plastic shavings and oil stains left after cutting plastic, appropriate organic solvents (such as alcohol) can be used for wiping.

     Regularly carry out deep cleaning of the cutting tools, including disassembling some components of the cutting tools (if permitted), and removing the chips and dirt inside. Keeping the cutting tools clean can prevent chip accumulation from affecting cutting accuracy, and also avoid dirt from corroding the tools.

Edge inspection and grinding

     Regularly check the wear condition of the cutting edge of the cutting tool. Tools such as magnifying glasses or microscopes can be used to observe whether there are any chipping or passivation on the cutting edge. For minor blunting of the cutting edge, it can be repaired by grinding. When grinding, professional grinding equipment and suitable grinding materials should be used, and precise grinding should be carried out according to the type of the cutting tool and the Angle of the cutting edge. For example, for straight-edge cutting tools, it is necessary to ensure that the cutting edge remains straight after grinding. For arc-shaped cutting tools, it is necessary to ensure that the arc shape after grinding meets the design requirements.
     Pay attention to the precision and quality control of grinding. The roughness of the ground tool edge should meet the requirements. Generally speaking, the roughness of the high-precision die-cutting tool edge should be at the micrometer level to ensure the accuracy and quality of the cutting.
