Factors affecting the sharpness of the cutter grinder machine

1. The influence of the installation and adjustment of the cutter grinder(knife grinder) machine on the grinding tool:

(1) The installation of the grinder of the cutter grinder(knife grinder) machine should be stable to prevent vibration, the fastener connection should be firm, and the cutter head should rotate smoothly to prevent jumping and swinging. Otherwise, the blade will not be sharpened and jagged edges will appear.

(2) The cutter head of the cutter grinder(knife grinder) machine should be perpendicular to the horizontal plane, otherwise the blade will not be sharpened.

(3) The position of the tool holder to be ground by the cutter grinder(knife grinder) machine should be 6 mm away from the surface of the disk and in the middle of the disk radius. If the position of the knife holder is not correct, it is easy to cause partial wear of the blade. The length of the boom will also affect the grinding stroke, shorten the grinding stroke, and make the blade sharp.

(4) For the mechanical drive type cutter grinder(knife grinder) machine, the V-belt should be properly tensioned to ensure that the cutter head reaches the rated speed. The low speed of the cutter head affects the grinding effect.

2. The influence of the abrasive composition of the cutter grinder(knife grinder) machineon the sharpening tool

(1) There is too much emery in the abrasive of the cutter grinder(knife grinder) machine, and a thick layer of emery is scraped off the edge, which is easy to wear and hard to sharpen.

(2) There is too little emery in the abrasive of the cutter grinder(knife grinder) machine: the blade is not easy to sharpen, the blade has a long grinding time, and it is easy to anneal and deform.

3. The influence of operation method on cutter grinder(knife grinder) machine

(1) The uneven pressure of the cutter grinder(knife grinder) machine causes the blade to eccentrically wear, and the sharpness of each tooth of the blade is inconsistent. When the blade swings, uneven pressure will cause the blade to bulge.

(2) If the pressure of the cutter grinder(knife grinder) machine is too high, it is easy to cause annealing and deformation of the blade. Shorten blade life.

         (3) If the pressure of the cutter grinder(knife grinder) machine is too small, the blade cannot be installed on the cutter head steadily, which will easily cause partial grinding, tooth beating and middle bulge.

(4) The cutter grinder(knife grinder) machine swing speed is too fast, it is easy to scrape off the abrasive, easy to break the knife teeth, it is difficult to grasp the blade balance, resulting in uneven pressure, easy to produce partial wear and middle bulge.

(5) If the swing speed of the cutter grinder(knife grinder) machine is too slow, the blade wear will accelerate, the service life of the blade will be shortened, and annealing will easily occur.

(6) The grinding stroke of the cutter grinder(knife grinder) machine is short, the blade cannot be sharpened, and the middle of the grinding disc surface is rapidly dented, which shortens the service life of the grinding disc. Therefore, the grinding stroke should be as long as possible.

(7) Use emery cloth on the cutter grinder(knife grinder) machine disc for too long: the blade is easy to anneal and deform.
