Classification of diamond circular saw blades

Publish Date:2020-09-09
Circular saw blade is the most commonly used sawing tool. Its diameter spans from Dia:105mm to 4800mm, and its thickness ranges from 0.1mm to 15mm. It has a wide range of uses, and its manufacturing methods are many and difficult. There are three main types of circular saw blades:

(1) The segmental saw blade includes the cold press. Sintered (Dia: 105mm-450 dry  cutter, and 350mm-4800mm marble and granite cutting blades manufactured by hot pressing and welding are the most versatile. Diamond sintered cutting blades, also known as tooth cutting blades. It is characterized by sharp cutting and long life, mainly used for cutting granite, sandstone, concrete, bricks, etc. According to the process, it can be divided into two types: sintered and hot-pressed sintered. The latter has a longer service life and safer. Welding according to different segment. The methods are divided into high-frequency welding and laser welding. There are also high-temperature framing weld methods in some countries and regions. Generally speaking, high-frequency welding is more suitable for stone cutting, while diamond laser welding professional cutting blades are used for concrete and asphalt roads, Refractory brick, bricks, building blocks, etc. Because laser welding strength will not decrease under cutting conditions without coolant, so it is suitable for field operations.

(2) Continuous rim saw blade. generally manufactured by cold pressing or hot pressing methods, including jade carving saw blades for jade cutting, dry and wet saw blade for other purposes. Diamond continuous rim cutting blade is also called diamond wet saw blade. Because the diamond blade is continuous, the cooling effect of cutting is not good. Generally, it is cut under the condition of adding water or coolant. This kind of cutting blade is generally more suitable for cutting and fragile Marble, ceramic tile, glass, quartz and other extremely brittle materials. Of course, it can also be used to cut granite, concrete, etc.

(3) The inner circle cutting disc is mainly used for cutting precious materials such as monocrystalline silicon. In order to save precious materials, its thickness is required to be very thin (b= 0.1-0.5mm), and it is generally manufactured by plating.

Diamond saw blade overview

2020-09-24
Diamond saw blade is a kind of diamond tool product used to cut hard materials such as stone and ceramic tiles. It is mainly composed of a high-strength alloy base and a diamond segment above. It is welded, cold pressed, hot pressed, etc. The base body and the segment are combined to form the finished diamond saw blade....

Diamond saw blade open

2020-09-24
In the initial stage of cutting the stone, the diamond saw blade needs to be opened. The process of opening is the process of exposing the diamond. If the blade is not opened, it is likely that the saw blade will not be able to cut in the early stage of cutting the stone. Of course, in the later stage, if the saw blade can't cut, but the wear of the blade is not enough, it is also necessary to open the saw blade twice or multiple times....

Maintenance and repair of diamond saw blades

2020-09-24
The diamond saw blade will be damaged during the cutting process, mainly including repeated welding segment, the wear of the blade body, the deformation of the blade body, bumps in the corners of the blade body, etc. How to repair and how maintenance the saw blades in good way can effectively reduce production costs. Long-term good use habits are also a kind of diamond saw blade maintenance....
