Abstract

PURPOSE:To keep best cutting quality and to avoid trace quantity of oils and fats, remaining of grinding scrap, and odor by letting a rotary grinding stone instantaneously rush in and run through from the outer periphery of grinding widths arranged like a hydraulic turbine to the inner periphery to be ground and washing grinding scrap with pressure. CONSTITUTION:The surface of a band file is controlled to a position lower than a working surface by an adjust screw 16, a soft rubber balloon 18 in a water tank 17 is expanded by working operation of a hard rubber balloon 18 to control draft of washing water B to a position in such a manner as to penetrate from a sponge 20 to a sponge 201. Whereupon, the washing water B is obtained from the sponge 201 to a sponge 202 by centripetal action of a rotary grinding stone 2, and surplus water is received by a sponge 203 to drop like a drop-by-drop titration in a waste water port. Some waste water drops in a waste water port through a clearance of a grinding stone table 4. The operation of pressing a cutting tool to the operating surface is such that the sponge 202 is rubbed to take up washing water B, which is distributed to the operating surface of the grinding stone 2 and grinding surface of the grinding stone 2 to be washed. The waste water adhering to the cutting tool is wiped out by the sponges 202, 203 and joined to circulating washing water.

Description

[Detailed Description of the Invention] (a) In industrial applications, surface processing is used to remove oils, fats, and oxidation adhered to cutlery, work parts, etc., and to align the cutting edge. A knife sharpener equipped with a cleaning device that guides the workpiece toward the inner ruler from an outer ruler equipped with a sponge, finishes it with a waterwheel-like array of grindstones, and collects the sharpening debris from the operating surface using centripetal action with circular cleaning water or air pressure cleaning. It's about machines.

(b) Conventional technology When cutting fatty foods, etc. with a cutlery, the habit of continuing the work while removing oil and adjusting slight distortions of the cutting edge, and sharpening the worn edge of the cutting edge, the tip of the blade that has stopped cutting, etc. There is almost no custom of removing oil, fat and oxides beforehand and aligning the cutting edge before climbing. Water or air cooling devices are used to suppress scratches on the whetstone caused by directly applying the sharp cutting edge to the whetstone to align the cutting edges, and to suppress frictional heat caused by the blade being pressed against the working surface of the rotary whetstone over a wide area.
In both cases, the adhesive material from the cutter is transferred to the working surface of the grinding wheel, and the scratches and clogging of the grinding wheel gradually expand, reducing the grinding ability and causing the grinding dust and cooling water to be scattered around due to the central action of the grinding wheel, causing pollution. Becomes the origin. The work is inefficient and difficult to obtain a high-quality finished surface as it is necessary to frequently repair the grinding wheel for clogging and uneven edges. Once sharpened, the knife was washed with boiling water to remove the smell of iron from the chemical changes that occur when the knife rubs against the whetstone, as well as traces of residual sharpening dust and fat.

(/arrogance) This invention utilizes the problem to be solved by the invention.The present invention is a groundwork for grinding using an outer annular band needle on the machined surface.The grinding amount can be adjusted using an external ruler and a wheel-shaped arrangement grindstone, and each receiver of an internal ruler.
