A sharpening stone tray is located within the top section between the guard rails and a sharpening stone is positioned within the tray. An electric motor drives the sharpening stone tray in reciprocating motion within a path parallel to the horizontal plane of the top section. A clamp unit is located over the sharpening stone and secures a cutting tool at a given angle on and in relation to the sharpening stone. The reciprocating movement of the sharpening stone allows for precise sharpening of the cutting tool secured in the clamp unit.
Description
- This application claims the benefit of provisional application Ser. No. 62/209,484, filed on Aug. 25, 2015.
- The present invention relates to the field of cutting tool sharpening operations for industrial, commercial, and home use.
- There are a variety of motorized sharpening devices available on the market which attempt to achieve the two primary goals of sharpening, accuracy and speed. Examples of such motorized devices are the Tormek Grinding System and the Work Sharp Disk Grinding System. However, these and similar systems are prohibitively expensive. They are devices which, by their nature, grind away a significant part of the cutting tool or blade with each use, another distinct disadvantage of these devices. In addition, the variety of grinding grits available to be used with such systems is limited and costly. As such machines are grinders, they are also large and bulky and thus are not portable. None have reciprocating sharpening stones, so they are less efficient as well.
- It is thus the object of the present invention to provide a unique honing apparatus for sharpening cutting tools which overcomes the limitations and disadvantages of existing tool sharpening devices.
- The present invention is a motorized honing apparatus which propels a variety of commercially available sharpening stones and diamond coated steels on a precision reciprocating path at approximately 200 rpm, allowing the user to sharpen a variety of tools, bits, cutters, blades, knives, scissors, and various other similar tools in a quick, efficient, and precise manner. The apparatus is configured to accept numerous types of honing stones, diamond coated steel plate sharpeners, ceramic backed abrasives, and glass backed abrasive stones.
- The honing apparatus of the present invention comprises a housing having a top section which is disposed in a horizontal plane. First and second guide rails extend along the sides of the top section. A sharpening stone tray is located within the top section between the guard rails and a sharpening stone is positioned within the tray. An electric motor drives the sharpening stone tray in reciprocating motion within a path parallel to the horizontal plane of the top section. A clamp unit is located over the sharpening stone and secures a cutting tool at a given angle on and in relation to the sharpening stone. The reciprocating movement of the sharpening stone allows for the precise sharpening of the cutting tool secured in the clamp.
- The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.
