Paper cutting machine is a necessary equipment for printing companies, and it is widely used in many industries such as printing and publishing, paper making, packaging, decoration and decoration. Its most basic function and application is cutting. The final actuator is the blade. On the one hand, whether the blade is good or bad and the use is reasonable affects the cutting quality directly. On the other hand, the unreasonable sharpening angle and use can severely damage the precision and the service life of the cutter. So using maintenance and sharpening the blade is the first step in the application and maintenance of the cutter
Paper cutter blade material and composition
The blade of the paper cutter is made by high-temperature insert welding of the blade and the body. The HSS (HIGH SPEED STEEL) or high-hardness chrome-tungsten-manganese (CrWMn) steel is usually used as the cutting edge, and hard alloys are used individually. The body part is usually made of mild steel. After the blade is quenched, the blade hardness can reach 60-64HRC.
Blade replacement
When the cutting force of the cutting machine is increased and the cutting sound changes significantly, it means that the blade has been used bluntly, and the sharpening should be promptly replaced.
Replacement steps:
1. When the blade is in the top position, turn off the power switch, stop the machine movement, put the machine in a shutdown state, place the machine in a rolling state, and turn the machine in the neutral position. When replacing the blade, loosen all the screws of the knife bed fastening blade, insert the attached knife wrench into the hexagon hole of the knife bed, and rotate counterclockwise, the blade will fall automatically, and the screw with the knife handle will be loaded into the blade. In the screw hole, holding the knife handle, the blade can be removed from the hook and placed on the attachment holder, and the insert can be put into the cassette for grinding.
2. The blade is fixed: First of all, the new blade should be inspected, the angle and width of the blade should be inspected, and the blade should be wiped clean with a soft cloth (rub the blade from the back to the edge, not against the blade Rub or rub along the edges. Then attach the attached tool holder wrench into the sharpened or replaced blade screw hole, place it on the attachment, push it near the knife bed, lift the blade and hang the two holes of the middle groove of the blade on the tool bed. On the extended hook, remove the knife handle, insert the knife wrench into the hexagonal hole of the knife bed, rotate clockwise, the blade will automatically rise to a fixed position. Tighten all the bolts securing the blade on the knife bed. Note that the entire process must be careful not to touch the blade with anything hard. Finally put away all kinds of tools, that is to complete the blade fixed.

The copying table is also called the writing table and the light-transmitting table. It is currently the most used in animation and comics and is an essential tool.When using it, you can overlap multiple drawings together, and you can clearly see the patterns on the bottom drawing. Using this function, you can easily copy the bottom drawing on the top paper. Therefore, many beginners of painting I will use a copy table to copy my favorite works.
