1: JYM21玻璃內外圓異形磨邊機是在JYM20型基礎上改進而來的一款機型，它除具備JYM20型的所有功能外，還能磨削內圓、內橢圓及各種異形內圓邊，是一臺多用機，性價比高。 2: 適用于加工平板玻璃，大理石的異形內外圓周邊的，斜邊、圓邊、橢圓邊、鴨咀邊等。 3: 采用真空將玻璃吸附在吸盤上，配電機驅動轉盤旋轉或單獨驅動盤上的一個獨立五星轉盤旋轉 。 4: 該機可加工回轉直徑700-2000mm戓100-700mm的異形平板玻璃。轉盤旋轉速度可在工作時任意調速，變速平穩(wěn)。 5: 本機氣缸也可以筒單形狀異形玻璃進半自動磨削，加工不同尺寸玻璃時磨頭升降可調，可以迅速改變磨輪位置和更換磨輪。 6: 磨削周邊時，可安裝三個磨輪進行粗、精磨和拋光；磨削斜邊時，安裝碗形磨輪，將磨頭向后傾斜調節(jié)斜面角度，用磨輪邊對玻璃進行磨削。   1: JYM21 glass inside and outside circular grinding machine is improved on the basis of the JYM20 a model, which all possess the function of type JYM20, but also can grind inner circle, ellipse and various special-shaped inner circular edge, is a multi use machine, high performance price ratio. 2: is suitable for the processing of flat glass, shaped outer circumference of marble, bevel edge, round edge, elliptic boundary, duck mouth edge. 3: uses glass is adsorbed onto a vacuum sucker, motor driven rotary plate or a separate disk drive is an independent five-star turntable rotation. 4: this machine can be shaped flat glass processing diameter 700-2000mm or 100-700mm. Rotating speed can be arbitrary in the work speed, steady speed. 5: engine cylinder can also single cylinder shape shaped glass into the semi automatic grinding, processing of different sizes of glass grinding down the adjustable, can change the grinding wheel position and replace the wheel quickly. 6: when grinding peripheries, install three coarse grinding, fine grinding and polishing; grinding hypotenuse, bowl shaped grinding wheel is installed, the grinding head tilted back adjustment angle, grinding of glass with a grinding wheel.
