Knives, such as knives, scissors, sickles, axes, etc., are worn when used for a long time and need to be sharpened again for reuse.

However, cutlery such as knives and scissors has various uses ranging from general items used at home to specialized fields such as peacocks or beauty and beauty. In addition, knives and scissors used in professional fields such as peacock, beauty, and beauty are expensive and require high precision of the product.

In particular, ordinary knives and scissors used at home are rarely used for grinding and reusing abrasive blades. However, expensive knives and scissors used in the field of specialty are frequently used when the blades become dull.

In general, however, such a polishing operation requires a considerable amount of time and a high degree of skill because the grinding operation is a method of reciprocating the grinding wheel while spraying water with the grinding blade. If you are not able to find a skilled worker or are being chased in time, you will have to do your own polishing, but because you are at high risk of a safety accident and you can not guarantee accuracy compared to an expert, most of you will make an uneconomic choice to buy a new cutlery .

In addition, in the case of grinding the surface of the abrasive wheel rotating at high speed by abutting the abrasive, there is an inconvenience that water should be sprayed from the gap to prevent frictional heat and dust generation. Since the abrasive must be laid down at an appropriate angle, In addition, there is a problem that the accuracy of polishing depends greatly on the skill of the operator.

The user can adjust the height of the support frame 700 according to the standard of the cutlery so that the blade of the cutlery can contact the surface of the grinding wheel 500. By adjusting the inclination of the support frame 700 in the longitudinal direction, By inclining it down, it is also possible to adjust so that an appropriate blade angle is formed.

Thereafter, the operation button 211 of the control panel 210 and the speed adjusting knob 212 are operated to select the rotating direction and the rotating speed of the polishing wheel 500. The blade of the cutler blade is polished by the rotation of the grinding wheel 500 according to the operation of the driving motor 400. At this time, fine particles in the direction of the grinding wheel 500 from the mist nozzle 600 on the grinding wheel 500 Water of the form is sprayed.

The water jet from the mist nozzle 600 can be performed by operating the operation button 211 of the control panel 210, and the amount and speed of the water to be sprayed can be appropriately adjusted. The water pump 800 draws water from the outside through the first supply pipe 910 while the water supplied to the water pump 800 flows through the second supply pipe 920, And is supplied to the nozzle 600.

On the other hand, the water sprayed from the mist nozzle 600 and the sludge generated during the polishing process are concentrated on the bottom surface of the water receiver 300 under the polishing wheel 500, and the discharge port 320 and the discharge pipe 321 And then discharged into a storage tank provided inside or outside the case 200. The user can prevent environmental pollution by treating the waste stored in the storage tank according to an appropriate procedure.
