What You Should Know About Diamond Saw Blades

 As a Gasoline Diamond Blade Manufacturer, share with you. Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics and so on. The diamond saw blade is mainly composed of two parts; the base body and the cutter head. The base is the main supporting part of the bonded cutter head.

The cutter head is the part that cuts during use. The cutter head will continue to be consumed during use, but the matrix will not. The reason why the cutter head can cut is because it contains diamonds, which is the most important part. Hard material, it friction cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.

Sintered Diamond Saw Blades

Sintered Diamond Saw Blades

 

Process classification

 

1. Sintered diamond saw blade: divided into cold pressing sintering and hot pressing sintering, pressed and sintered.

2. Welding diamond saw blades: divided into two types: brazing and laser welding. Brazing is to weld the cutter head and the base through a high-temperature melting medium, such as high-frequency induction brazing saw blades, vacuum brazing saw blades, etc.; laser welding The contact edge of the cutter head and the substrate is melted by a high-temperature laser beam to form a metallurgical bond.

3. Electroplating (brazed) diamond saw blade: the blade powder is attached to the substrate by electroplating. Since 2012, the country has gradually eliminated the production of electroplated diamond products, mainly because of serious pollution.

Different types of diamond saw blades are selected for different materials, and different powder formulations are suitable for the characteristics of different materials, which have a direct impact on the quality, effect, pass rate, and cost and benefit of the material product.

The factors that affect the efficiency and life of diamond circular saw blades include sawing process parameters, diamond particle size, concentration, and bond hardness. According to the cutting parameters, there are saw blade linear speed, sawing concentration and feed speed.

 

Saw blade speed:

 

In actual work, the linear speed of diamond circular saw blades is limited by the equipment conditions, the quality of the saw blade and the nature of the sawn stone. In terms of the best service life and cutting efficiency of the saw blade, the linear speed of the saw blade should be selected according to the properties of different stones. When sawing granite, the linear speed of the saw blade can be selected within the range of 25m～35m/s. For granite with high quartz content and difficult to saw, the lower limit of the saw blade linear speed is appropriate. In the production of granite tiles, the Sintered Diamond Saw Blades used are smaller in diameter, and the linear speed can reach 35m/s.

Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone materials, and ceramics. The diamond saw blade is mainly composed of two parts; the base body and the cutter head. The base body is the main support part of the bonded cutter head. The cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the matrix will not. The reason why the cutter head can cut is because it contains diamond, and diamond is the most important part. A hard substance that rubs and cuts the workpiece in the cutter head. The diamond particles are wrapped by metal inside the cutter head. There are often some problems in the use of diamond saw blades . How to solve these problems? 1. The thickness of the cut sheet is uneven (1) The basic tension is not suitable; the saw blade tension needs to be re-corrected. (2) The screw of the fixed trolley screw bearing seat is loos

What are the dressing methods for diamond grinding wheels?

  1. Grinding and dressing method When dressing the diamond grinding wheel, the silicon carbide abrasive grinding wheel and the diamond grinding wheel are used for grinding. The diamond grinding wheel rotates, while the silicon carbide abrasive grinding wheel also performs the feeding motion while rotating, and the surface of the diamond grinding wheel is ground. The particles start to rotate slowly under the action of friction, and at the same time, a certain extrusion force is generated on the metal bond. With the continuous action of the friction force, the dull diamond particles fall off the surface of the grinding wheel, and the sharp diamond particles are exposed. out to achieve the purpose of diamond grinding wheel dressing. The main advantages of the grinding dressing method are: simple structure, convenient operation, short dressing time, stable grinding speed, low grinding cost, high dressing precision, and easy control of shaping quality. It is mostly used for dressing ceram

GET TO KNOW YOUR DIAMOND BLADE Understanding your diamond blades   can help you make educated decisions in the field, save time and decrease the chance of injury. In this post, we will break down the components of a diamond blade, and the functions of each part. Parts of Blade SEGMENTS The segment is best described as the ‘ teeth ’ around the blade. There are two parts that make up a segment, the bond, and the diamond. It is important to note that the segments do not cut material like a blade used to cut wood. Instead, they grind away the material with their diamonds, which do all of the grinding work. The amount of diamonds, quality of diamonds, and the size of the diamonds in a segment all factor into cutting speed and the life of the blade. The bond holds
