Glass mirror paint surface cutting tool and cutter wheel thereof

Technical Field

The utility model relates to a glass mirror finish cutting technical field, concretely relates to glass mirror finish cutting tool and break bar thereof.

Background

In the production process of the glass mirror, a large piece of glass is generally flatly placed, then the upper surface of the glass is processed by two methods of chemical silver plating or vacuum evaporation plating to prepare the upper surface of the glass into a metal layer for reflection imaging, and then a paint layer is covered on the metal layer; finally, the large mirror block can be cut into the required size.

Cutting is usually performed by a glass cutter; a glass knife refers to a tool used to cut glass. The part of the glass cutter used for cutting is made of diamond or alloy material which is harder than glass, and the part is arranged on the cutter head. The glass cutter head is ground to have a relatively large angle and sharp cutting edge. The blade leaves a very sharp-bottomed groove in the glass by scratching the surface of the glass with a glass knife. The face of the glass ribbon is then pulled and the glass of the brittle material is easily broken along the ribbon due to the high stress concentration at the sharp groove bottom.

However, when the upper surface of the glass mirror is cut by the glass knife, the upper surface of the glass is covered with the metal layer and the paint layer, so that the glass knife can generate certain obstruction in cutting the glass mirror, and the cutting edge is difficult to leave a groove on the glass; for this reason, the cutting is usually completed by turning the glass mirror over and directly applying a blade to the glass; however, when the glass mirror is produced, in order to improve the production efficiency, a large piece of glass is often adopted, so that the glass is very time-consuming and labor-consuming when being turned over and is easy to collide with.
