Glass Edging / Polishing Machine

This is special equipment for finishing the edges of glass sheets in the industry of glass fabrication. The machinery is crucial in the production of a smooth, polished, and safe edge on glass products. Glass edging and polishing are common processes after cutting glass into the desired size and shape, ensuring quality products for the intended application.

Key Features and Functions:

Glass Edge Grinding: Most glass edging machines are used in grinding rough, sharp edges of cut glass to obtain smooth edges. This is achieved through abrasive wheels or belts, producing different kinds of edges such as pencil edge, flat edge, and beveled edge, depending upon the finish to be achieved.
Polishing: The edges can be smoothened and made shiny after grinding. This process is normally achieved by using finer abrasive materials or by polishing wheels. Polish edges enhance the appearance of the glass and make it safe to handle.
Automation and Precision: Most of the glass edging and polishing machines of recent times are fitted with CNC systems, allowing perfect management of the grinding process. Thus, it is possible to obtain perfect results for complex shapes and edge profiles.
Water Cooling: Water is normally used to cool the glass and the grinding wheels during the grinding and polishing process. This prevents overheating and hence, breakage of the glass. It also cleans glass dust and other debris during the process

Heating: Glass tempering involves heating the glass initially to about 600-700°C (1,112-1,292°F), slightly below its melting point, which makes it soft and malleable.
Quenching: The glass, after heating, is cooled rapidly by high-pressure air blasts. This rapid cooling will solidify the outer surfaces quickly and cool the inner layers more slowly, thereby creating compressive stresses on the surface and tensile stresses inside.
Strengthening: This controlled heating and cooling make tempered glass four to five times stronger than regular glass, giving it strength and a unique pattern of breakage.

Types of Edging/Polishing Machines.

Straight Line Edging Machines: Used to attain straight edges and by far used a lot in processing flat glass sheets. They give out different edge finishes like flat, beveled, and pencil edges.
Curve Edging Machines:These machines are used for edging and polishing curved or irregularly shaped glass pieces into such items as mirrors, table tops, various decorative glass articles, etc.
Double-edging machines: It can handle two edges of the glass sheet simultaneously, hence increasing efficiency and output.
