Besides the ordinary glass cutting machine, what other tools are there for cutting glass?

There are also laser knives, water knives, diamonds, fiber knives, files and so on.

First, the optical fiber cutter

The optical fiber cutter is used to cut the timely glass optical fiber as thin as a hair. The cut optical fiber can be used for device packaging, cold bonding and discharge welding after being enlarged hundreds of times.

Second, the water knife

Water knife, that is, water as a knife, is called high-pressure water jet cutting technology, which originated in the United States. Used in aerospace military industry. It is favored because cold cutting will not change the physical and chemical properties of materials.

Through the continuous improvement of technology, pomegranate sand, emery and other abrasives are mixed into high-pressure water to assist cutting, which greatly improves the cutting speed and cutting thickness of water jet. Water knives have been widely used in ceramics, stone, glass, metal, composite materials and many other industries.

In China, the maximum pressure of water jet has reached 420MPa. Some technologically advanced companies have perfected 3-axis and 4-axis water knives, and 5-axis water knives are becoming more and more mature.

Three. Diamonds (diamonds)

Diamonds are commonly known as "Jin Gangzuan". That is, we often say that the original diamond is a mineral composed of carbon, which is an allotrope of carbon. Diamonds are the hardest substance in nature. Diamonds are widely used, such as handicrafts and industrial cutting tools. Graphite can form synthetic diamond at high temperature and high pressure. It is also a precious stone.

Fourth, high speed steel.

High-speed steel has good technological properties and good combination of strength and toughness, so it is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies.

In addition to high-speed steel produced by smelting method, powder metallurgy high-speed steel appeared after 60' s. Its advantage is that it avoids the mechanical property degradation and heat treatment deformation caused by carbide segregation caused by melting method.

Verb (abbreviation for verb) file

There are many fine teeth and strips on the surface of the file, which is a hand tool for filing workpieces. Used for the micro-machining of metal, wood, leather and other surface layers.

The earliest documentary records in the world originated from Greek literature. According to records, the Crete civilization in Greece invented bronze file around 2000 BC, the earliest copper file was invented by the ancient Egyptians in 1300 BC, and the iron file was invented around 700 BC. Western records show that the ancient Romans made files with carburizing heat treatment technology around 1 100.

However, it is believed that carburizing technology was widely used to process files in ancient China during the Qin and Han Dynasties around 200 BC. A file unearthed from the Han Tomb in Mancheng (BC 1 13) proves this statement-"slender, with one end broken. Nearly half of one side is chopped with a water plane file, and 1 cm has six teeth.

Similar to the "horse tooth file" at the beginning of 2 1 century, it belongs to the type of wooden file. The rest is 20.4 cm long, 1 cm wide and 0.3-0.5 cm thick.
