Description

Multi-function grinding machine

The present invention relates to a grinder, and more particularly to a grinder having a multifunctional and replaceable grind fixture.

In addition to the key engraving, the general key shop also has the business of carving seals for consumers. In addition to providing diversified services, it can also increase the revenue of key stores.

Therefore, the operator of the key shop often encounters the problem that the key blank is too long, the seal engraving is wrong, and even the bit used to process the lock is worn.

Usually, the key embryo produced by the factory will be longer than the length of the key to be re-engraved, so the locksmith will usually use a steel cutter to repair the short key embryo, or use a trowel to sharpen the end of the key embryo; When the engraving is wrong, if the locksmith does not directly discard the seal, it is the end face carved by the hand-timed smoothing stamp; and, when the drill bit is worn, it also relies on the locksmith to hold the drill bit by hand to abut the grinder. And grinding.

Therefore, the current practice of the above problems will cause the key shop operators to spend too much time on refining and grinding without working efficiency. If the locksmith directly discards the stamp of the wrong engraving, it will even cause material cost. In addition, the grinding wheel of the grinder is not convenient to replace after wear, which also increases the time for the operator to work.

The purpose of this creation is to improve the prior art, because the time required for the key embryo, seal and drill grinding is too long, the grinding wheel of the grinder is time-consuming to replace, and even the seal of the engraving error is directly discarded to improve the cost of the material, etc. The implementation of the creative technology means that the user can quickly and conveniently handle the grinding operation of the above-mentioned objects, and the replacement of the grinding parts is more convenient, thereby improving the efficiency of the related work.
