性能特点：
1、机械结构保证两侧组角刀同步进给，防止窗角错位；
2、可以制作宽度不小于220mm的窗户；
3、专利型的双层刀架，使上下两层刀具位置相对可调，从而能完成隔热窗双层错位角码的组角；
4、机器的控制和工作动力只需要压缩空气，故障点少，易于维护维修。
Performance characteristics:
1, mechanical structure ensures that both sides group angle cutter synchronization to feed, to prevent the window angle dislocation;
2, can make the window width not less than 220mm;
Double knife 3, patent, the cutter location on the two floor is adjustable, which can complete heat insulation window double dislocation and the group angle;
4, control of the machine and working power only need compressed air, few fault points, easy maintenance and repair.
