Material classification of precision glass tubes
Precision glass tubes can be divided according to materials: high silicon borosilicate glass tubes, quartz glass tubes, neutral borosilicate glass tubes, crystal glass tubes, ordinary glass tubes, and special glass tubes.
High silicon borosilicate glass tube
Compared with ordinary glass, high-silicon borosilicate glass tubes have no toxic side effects. Its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties are greatly improved. It can be widely used in chemical industry, aerospace, military, household, In various fields such as hospitals, it can be made into lamps, dials, telescopes, observation holes for washing machines, microwave oven trays, solar water heaters and other products.
Cutting principle of glass materials
The cutting of glass utilizes the brittleness and residual stress of the glass to create a score at the cutting point to cause stress concentration. Under the action of external force, the fracture line spreads along the direction of the stress, thereby achieving the purpose of cutting the glass. For glass plates and glass tubes that are not too thick, diamond cutting blades or other tough tools can be used to cut and break them directly.At present, there are two kinds of processing of precision glass tubes: one is high temperature with hot processing technology, and the other is precision mechanical shaping with cold processing technology.
Moresuperhard's diamond cutting wheel for precision tubes
Moresuperhard offers resin diamond cutting discs and metal diamond cutting discs specifically for cutting in the glass industry. It can be used to cut glass optical devices such as quartz glass, K9 glass, coated glass, etc. It can also be used to cut various glass tubes, glass spouts, high borosilicate glass tubes, capillary glass tubes, quartz glass, and crystallized glass.
Advantages of cold diamond cutting disc for glass tubes
1. Good self-sharpening, sharp cutting, high efficiency, easy to achieve large cutting depth and large feed
2. The bonding agent is elastic and can improve the processing quality and workpiece finish.
3. Few or no trimming times required
4. The cutting edge is smooth and burr-free
When cutting long glass tubes, both ends of the glass tube must be fixed to avoid edge explosion.
In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
