Raw material selection and preparation

The selection and preparation of raw materials for diamond saw blades is a key step in the manufacture of high-performance saw blades. The following is a detailed analysis of the selection and preparation of raw materials for diamond saw blades:

I. Raw material selection

Diamond particles

Diamond particles are the main cutting part of diamond saw blades, and their grade, particle size and concentration have an important influence on the cutting performance of saw blades.

Grade: Select high-quality diamond particles to ensure that the saw blade has excellent wear resistance and cutting efficiency.

Grain size: Select the appropriate diamond grain size according to the different cutting materials. The larger the grain size, the higher the cutting efficiency, but the wear resistance may be reduced; the smaller the grain size, the better the wear resistance, but the cutting efficiency may be affected.

Concentration: The concentration of diamond particles in the saw blade also needs to be adjusted according to actual needs. Too high a concentration may cause the saw blade to be too hard and easy to break; too low a concentration may affect cutting efficiency and durability.

Metal Powder

Metal powder is used to form the metal carcass of the diamond saw blade, which encapsulates and bonds the diamond particles.

Suitable metal powders, such as ferrosilicon, nickel-chromium alloy, etc., are selected to ensure good bonding and wear resistance between the metal carcass and the diamond particles.

The particle size, shape and distribution of the metal powder also need to be strictly controlled to ensure the overall performance and stability of the saw blade.

Bonding agent

Bonding agent is used to enhance the bonding force between diamond particles and metal powder to improve the overall strength and durability of the saw blade.

Organic resin or metal powder can be chosen as the bonding agent, depending on the application scenario and performance requirements of the saw blade.

Preparation of raw materials

Mixing

Mix the diamond particles, metal powder and bonding agent in a certain proportion. During the mixing process, the mixing time and temperature should be strictly controlled to ensure the uniform distribution and good combination of the raw materials.

Molding

Put the mixed raw materials into the mold, through the cold or hot pressure molding to the required shape and size. During the molding process, parameters such as pressure, temperature and time need to be controlled to ensure the molding quality of the saw blade and the uniformity of the diamond particles distribution.

Pretreatment

Before sintering or welding, pre-treatment of the saw blade, such as cleaning and drying, may be required to ensure the cleanliness and bonding of the saw blade surface.

III. Precautions

Raw material quality

Ensure that the quality of all raw materials meets the relevant standards and requirements, in order to avoid any deterioration or damage to saw blades caused by raw material quality problems.

Ratio of raw materials

Adjust the ratio of diamond particles, metal powder and bonding agent according to the actual demand in order to obtain the best cutting performance and durability.

Process Control

Strictly control the process parameters of raw material mixing, molding and pre-treatment to ensure the stable and reliable quality and performance of saw blades.

In summary, the selection and preparation of raw materials for diamond saw blades is a key step in the manufacture of high-performance saw blades. By selecting suitable diamond particles, metal powders and bonding agents, and strictly controlling process parameters such as raw material mixing, molding and pretreatment, diamond saw blades with excellent cutting performance and durability can be produced.
