There are two glass edging machines: drench type glass sanding belt grinding machine and full automatic glass grinding line, the drench type grinding machine price is cheap to about US$5000, suit for new glass factory, the full automatic grinding line is fast and expensive, suit for big auto glass factory.

Dripping Glass Belt Grinding Machine

The dripping glass belt grinding machine is suitable for grinding flat glass of thickness 1.1~6mm. Rough grinding, fine grinding and C-angle of the four corners of the glass can be completed at one time, using imported double linear guides and double rolling ball screw to achieve stable moving speed and grinding accuracy. The grinding glass width adopts touch screen input, automatic adjustment, variable frequency speed glass transmission, touch screen + PLC control. Directly set the glass width and running speed to grind the edge production. Widely used in the deep processing of auto glass, furniture glass and mirror frame glass.

Working Principle

Receive the glass from the first grinding machine – fast moving – the front end of the glass touches the fixed side stop bar relative to the grinding machine – the glass changes direction by 90 degrees – enters the second grinding machine.

Dripping glass sanding belt grinding machine product features.
(1) Good edge grinding effect, which can achieve the edge grinding effect of CNC four-sided grinding.

can solve the problem that four-sided grinding cannot grind small pieces of glass below 800mmx600mm.
Can grind part of the shaped glass: such as triangle, trapezoid, semi-circle, circle, part of the wave shape, etc.
Can grind the safety angle, reducing the safety risks (which is also one of the functions that the four-sided grinding does not have).
