The Cutting Technology and Development of Tungsten Carbide Glass Cutting Wheels

Published On: August 28, 2020

With the wide application of LCD in mobile phones, tablet computers, TV, and automobile, people pay more and more attention to cutting quality and efficiency of its matching processing equipment. In the production and manufacturing of LCD, in order to improve production efficiency, reduce manufacturing cost, and form large-scale batch production, it is often to make multiple LCD displays on a large glass. After screen printing, there are several groups of LCD units on glass after screen printing. These small units should be separated before liquid crystal infusion can be carried out. The cutting process is to split the glass of the whole box into two groups. The monomer of liquid crystal display. At present, common cutting technologies include glass cutter wheel cutting, laser cutting, and water jet cutting. The demand for Tungsten Carbide wheels for Cutting Glass is rising now.


First of all, the empty liquid crystal cell prepared in the previous process is fixed on the cutting table of the Tungsten Carbide Glass Cutting Wheel. Cemented carbide glass cutting wheel is scratched along cutting mark on glass under a certain pressure to form an incision with the same depth and width on glass. Accuracy and speed of equipment directly affect product quality and production efficiency. The trajectory of the glass cutter wheel is called the cutting line. During cutting, there is a cutting mark on four corners of each group of LCDs.


In cemented carbide glass cutting wheel cutting process, the LED electrode surface of LCD is exposed, so the display can be divided into upper and lower glass sizes. After confirming upper and lower pieces, fix glass on cutting machine platform, set cutting data (including cutting times and step distance), adjust cutting depth and cutting pressure of tungsten Carbide Glass Cutting Wheel, and make trial cutting at the edge of glass without graphics. After adjustment, batch cutting can be carried out. The principle of splitting is to apply a certain pressure on the back of the glass with cutting knife marks to make the glass deform slightly and the glass will crack along the cutting line. For the convenience of filling liquid crystals, split liquid crystal cells should be put into a special basket. After filling the liquid crystal, the liquid crystal box strip should be cut into the liquid crystal cell unit by a cutting machine.


Tungsten Carbide Wheel for Cutting Glass cutting has a history of several decades. With the development of glass technology, wheel cutting technology, equipment, and cutter wheel have developed. From the tungsten Carbide Glass Cutting Wheel (commonly known as tungsten steel cutter wheel) for cutting ordinary flat glass and float glass, it has upgraded to an ordinary diamond cutter wheel for cutting TFT-LCD panel, substrate glass, touch screen, and high permeability micro tooth diamond cutter wheel.

Key of Carbide Glass Cutting Wheel cutting technology is cutting equipment, Tungsten Carbide Wheel for Cutting Glass cutting, cutter shaft and tool holder Cemented carbide glass cutting wheel is key, and cutter wheel technology develops with the development of glass technology.
