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 the grinding industry, ceramic diamond double-end grinding discs have attracted much attention for their high efficiency and high precision. In order to help newcomers quickly master the core knowledge in this field, Moresuperhard specially invited Jim, a sales expert in double-end grinding discs, to conduct a systematic training. From basic concepts to practical applications, this training content is full of practical content. Of course, in order to test the learning results, Jim assigned homework to everyone. The students' answers are all very good, which are summarized as follows for everyone to learn and refer to.
Moresuperhard is committed to manufacturing diamond grinding wheels that can grind a variety of materials such as carbide/ceramic/cermet and PCD/PCBN. In addition, the grinding performance of our company's grinding wheels is very good, because the main focus of the design of the grinding wheels is to shorten the production cycle and increase the dressing interval, which can improve the production efficiency of customers while also taking into account the excellent finish and uniform edge of the blade.
