The invention discloses a glass edge grinding device for engineering, and belongs to the field of construction engineering equipment. The limiting strip is an L-shaped strip, a water tank is fixed onthe side of the limiting strip, and a water pump is fixed at the left end of the limiting strip, a grinding wheel is arranged on a main shaft of a motor, a controller is fixed on the limiting strip, and the motor is fixed on a motor base; a return type ring is installed on a second support, a first fixing nut is installed on a first support, a handheld support is fixed on the limiting strip, and ashielding plate is fixed on a third support; a second fixing nut is arranged in the center of the side face of the motor base. According to the device, the angle of the first support and the distancebetween the first support and the glass can be adjusted by unscrewing the first fixing nut and the second fixing nut, so that the angle and depth of the grinding are changed so as to adapt to different production requirements, so that the precision of grinding is guaranteed by moving of the limiting strip attach tightly in one side of the glass, and the working quality and efficiency are improved.
