And improve economics, and form the processing roller as a cylindrical flat roller made of a mixture of epoxy and abrasive, thereby minimizing vibration and noise that may occur during the polishing operation of the product. This relates to a possible curved polisher.

In general, as a device for finely polishing natural gemstones and artificial gemstones including crystals, sapphires, cubic, diamonds, etc., many jewelry processing apparatuses are used. He proposed a patented jewelry processing device (Patent Registration No. 0940278) dated.

Looking at the characteristic configuration of the conventional jewelry processing apparatus, the base frame; A polishing wheel which is rotatably installed in a state connected to a motor through a rotating shaft on an upper end of the base frame and forms a jewelry work in a set form; A jewel holder, which is adhesively fixed in a state in which a jewel for a work is held, and has a trapezoidal binding portion at one side; A holder fixing bar and a holder fixing means fixedly positioned at an upper end of the polishing wheel through a support bracket to bind and fix the jewelry holder to correspond to the polishing wheel; The holder is fixed to one end of the holder fixing bar, and rotates the holder fixing bar downward in accordance with the motor driving for the pore of the crown, pavilion, girdle of the pore of the jewelry. Inclination adjusting means; The jewelry is rotatably installed at the other end of the holder fixing bar, and the jewelry is held while rotating by driving the motor to form a pore surface at the crown, pavilion, and girdle of the pore portion of the jewelry. A holder spindle rotating part for rotating each spindle of the holder; Holder lifting means for lifting and lowering the holder fixing bar according to an initial setting and punching work for punching the gemstone adhered and fixed to the gemstone holder; Four or more polishing wheels, which are configured to control the driving of the motor connected to the polishing wheel, the holder lifting means, holder tilt adjusting means and the holder spindle rotating portion, and corresponding to the entire process of jewelry work for the polishing wheel. Each of which is installed on one base frame in a state connected to each motor through a rotating shaft, and the jewelry holder is slid left and right slided from the polishing wheel by the left and right operating plate transfer means installed at both ends. The left and right operating plate for making the jewelry in the set form is characterized in that the binder is fixed to the lower end of the support bracket formed on both sides of the holder fixing bar in the state of interpolating the entire polishing wheel.

In the case of such a conventional jewelry processing apparatus, only the surface polishing is performed by pressing a rotating force on the rotating polishing surface to form several facets around the jewelry, and the conventional jewelry processing apparatus for the three-dimensional curved polishing processing.
