每條大梁高低、前后能獨立調(diào)節(jié)。

前后調(diào)節(jié)：玻璃靠輪與大梁行成90°角，因為玻璃開介出來都是矩形90°角。

高低調(diào)節(jié)：使大梁左右水平勻稱，因為玻璃是平直的。

作     用：玻璃磨邊時上下磨輪和玻璃頭部、尾部、上下倒棱、過底接觸面受力均勻，不易擠碎玻璃；玻璃磨邊效果頭部和尾部、上面和下面都一致，保證玻璃除膜時頭尾寬度一致，玻璃越大越能體現(xiàn)效果。

Each beam can be independently adjusted in height, front and rear.

Front and rear adjustment: the glass backup wheel forms a 90 ° angle with the beam line, because the glass opening is rectangular 90 ° angle.

Height adjustment: Make the main beam level and symmetrical on both sides, as the glass is straight.

Function: During glass edge grinding, the upper and lower grinding wheels and the contact surfaces of the glass head, tail, upper and lower chamfers, and bottom are evenly stressed, making it difficult to crush the glass; The glass edge grinding effect is consistent at the head and tail, top and bottom, ensuring that the width of the head and tail is consistent during glass film removal. The larger the glass, the better the effect.
