Abrasive quality control

First, the quality of abrasives

1) There are large particles in the abrasive. Causes scratches.
2) Different manufacturers, the same specifications of abrasive products, the difference in particle size specifications is too large, and some even cross the grain size number. Lead to unstable product performance.
3) Abrasives of the same grade, the actual strength of the sharp and durable cutting wheel varies greatly, resulting in unstable product performance
4) The impurity content and content in the abrasive are unstable. This results in unstable product performance; it also affects the performance of the workpiece being ground for more demanding grinding objects.
The quality problems that often occur at present are mainly reflected in the above four aspects. The following four aspects are introduced on how to conduct quality control.
Second, abrasive quality control

1) Abrasive large particle control. thin flat cutting disc For single crystal diamond abrasives, the size fractionation is usually carried out by a sieve sieving method. Since the standard is unreasonable for large particles, large particles often appear in the single crystal abrasive. Especially for 80/100 abrasives for fine grinding applications, large particle inspections must be carried out before use. If the manufacturer wants to control large particles, it is necessary to reduce the upper limit sieve of the inspection sieve by one number, so that the large particles can be effectively controlled.

The user has to control large particles, and can filter out large particles by sieving. Microscopic image method can also be used to inspect large particles. It is found that large particles should be treated or replaced. Diamond micronized abrasives are usually classified by sedimentation method. Since there are no practical standards at present, the definition and understanding of large particles are currently inconsistent. Therefore, it is not surprising that large particles often appear in micronized products.

In order to control large particles, the production unit must first control the settlement time of the stopper particle size to ensure that the large particles are blocked outside, and at the same time pay attention to the production links without any pollution. Especially in the production of fine powder of 5μm, the production environment must be clean. As a user, it is currently necessary to examine large particles in micropowder using only microscopic image analysis. For the definition and analysis of large particles, please refer to the contents of the fifth lecture.

2) For single crystal diamond abrasives, the products of the same specification, different manufacturers and different batches have great differences, and some even differ by one grain size. This will have a greater impact on the use of the effect. The manufacturer shall strictly inspect the screen used to ensure that the screen meets the standard requirements in order to ensure that the particle size of the single crystal diamond abrasive product of the same specification of different batches and different manufacturers is stable.

For the user, it is also necessary to use a qualified screen for quality inspection. For the user, the one-to-one particle size composition is an important factor to ensure the stability of the use effect. Therefore, the particle size composition of the product should be strictly checked. The method by which the user controls the particle size composition is a screening method and an image analysis method. For the diamond micropowder, a microscopic image method, an electric resistance method, or a laser diffraction method can also be used.

cut off disc for stainless steel

Abrasives products are mainly used for machining various parts in machining, cutting, grinding, polishing and grinding of various materials. The products processed by the abrasive grinding tools have high precision and good surface finish; the workpiece does not generate machining stress, and the geometrical tolerance can be effectively controlled. A special-shaped surface, a sealing surface, a mounting reference surface, and an appearance quality, which are generally required to be required, are all completed by an abrasive tool.7″ cut off disc for stainless steel The metallurgical industry is generally used for surface treatment of steel embryos. The automotive industry is used for coating treatment of its main gate crankshaft, cam, engine machining and exterior surfaces. In addition, furniture, leather, advertising equipment, electrical appliances, etc. all require abrasive abrasive products to complete. It is also widely used in industries such as construction, geological exploration and resource exploitation. Abrasives products are a special tool in the manufacturing industry and a basic industry closely related to the national economy and people’s lives.

Machining should be based on the material of the part to select abrasive products: general materials are carbon steel, alloy steel, cast iron, hard bronze and other parts with high tensile strength, optional brown fused alumina abrasives; the material is hardened steel, High-carbon steel, high-speed tool steel and other high-hardness parts, optional strong white jade grinding tools; coated abrasives and super-hard materials, selected for the softness and hardness of the parts and special processing conditions, also The abrasive can be formulated according to the performance index of the material, and the size and quantity of the abrasive can be determined to meet the processing needs.

How to use abrasives in machining to maximize the effectiveness of abrasives. First of all, 7″ cut off disc for stainless steelwe should understand the type of abrasive tools and the relatively suitable materials. At present, there are three main types of abrasive products:

(1) Ordinary type, including corundum series and silicon carbide, resin abrasives, ceramic abrasives, etc.;

(2) coated abrasives, including abrasive cloth, sandpaper, abrasive belts, etc.;

(3) Superhard materials, mainly diamond, cubic nitride and products.

Use resin cutting blades to pay attention to 4 details

In order to be able to achieve safe production and increase production efficiency, some details of the use of the resin standard cut off wheel for metalrequire special attention:
1. When the cutting is not sharp, the cutting piece should be trimmed and edged. If it continues to be used, it will cause overheating and overload, and the cutting piece will be damaged. Also, it should be noted that the cutting piece is strictly prohibited for operations other than grooving or cutting, and abnormality due to uneven force is avoided.
2. In the rotation of the cutting piece, it is strictly forbidden to cut by hand, and the cutting piece cannot be touched by hand or body. Also, if abnormalities are found during the cutting process, stop immediately. Also note that when the cutting piece is marked with the direction of rotation, it must be in the same direction as the machine tool. On the contrary, the cutting is not sharp, and it is difficult to exert the performance of the cutting piece.
3. If a cutting piece that does not match the cut workpiece is used, it is prone to abnormal wear, poor sharpness, abnormal heat, and the like. In addition, it should be noted that when the flange is too small or the precision is poor, the cutting piece is easily damaged. Please use it after improvement.
4. Please check carefully before installing the cutting piece to confirm whether the cutting piece has deformation, crack, and collapse.
When using the resin dicing sheet, as long as you pay attention to the points mentioned above, there will be no major problems.

Grinding wheel quenching

Why should water be cooled frequently when grinding a high hardness tool that has been quenched and tempered on a grinding wheel?7″ cut off disc for stainless steel
Cutting is a physical movement. Narrowly defined cutting refers to cutting objects (such as food, wood, and other objects with low hardness) with a sharp tool such as a knife; generalized cutting refers to the use of tools, such as machine tools, flames, etc., to make objects under pressure or high temperature. Disconnected.7″ cut off disc for stainless steel
The grinding wheel spindle is overheated because the gap between the main shaft and the bearing is too small, there is debris between the bearings, the bearing is worn, the lubricating oil is not enough or leaks, and the lubricating oil is used incorrectly, which makes the bearing lubrication poor.
High-hardness tools after quenching and tempering produce high temperatures during grinding, often using water cooling to prevent workpiece annealing. For example, we grind white steel cutters on the grinding wheel, and if it is not water-cooled for a long time, the white steel cutter will produce an annealing phenomenon (feeling like burning) and lose the hardness, and the cutting work cannot be completed. Grinding for a while, cooling in water, is also a quenching process to maintain the hardness of white steel. Carbide-like tools or cutting tools are not allowed to be cooled by water during grinding. Therefore, the hard alloy has good red hardness and will not be annealed at high temperatures. Conversely, if water is continuously used during grinding, the cemented carbide will break due to the large internal and external temperature difference, causing damage.
Steel tools generate a lot of heat during grinding. If they are not cooled, the hardness and rigidity of the product will decrease, which will affect the quality and service life of the product. Using water cooling to lower the workpiece temperature maintains workpiece performance.
Cemented carbide materials are resistant to high temperatures and are brittle. In the case of quenching and rapid heat, the product may crack.

The service life of the grinding wheel

Any grinding wheel has its own wear requirements. If the wear is reached to a certain extent, it must be replaced with a new one. It is not necessary to use excessive wear in order to save materials. This is a very unsafe violation. It is generally stipulated that the new grinding wheel should be replaced when the grinding wheel is worn to a diameter 10 mm larger than the diameter of the chuck.7” cut off disc for metal
The actual grinding time between two dressings of the grinding wheel is called the wheel life. Judging the life of the grinding wheel is generally determined visually based on the phenomenon produced after the working surface is worn. The main phenomena are: self-excited vibration in the grinding process, regenerative vibration on the surface of the workpiece; increased grinding noise; grinding burn on the surface of the workpiece, sharp increase or decrease in grinding force; reduction in grinding precision; grinding surface The roughness is increased. These phenomena are mainly caused by thermal damage to the surface of the workpiece due to excessive grinding temperature and a decrease in roughness and precision due to self-excited vibration.
7” cut off disc for metal,End of life of the grinding wheel: the surface passivation of the grinding wheel is in a smooth state (which will increase the grinding force and grinding heat); the grinding wheel is clogged (prone to vibration or noise and to burn); the contour of the grinding wheel is destroyed (affecting the machining accuracy).

Forming wheel dressing

In addition to the correct use of the corresponding dressing tools when trimming the grinding wheel, the following finishing methods must not be ignored:

The ability of the grinding wheel to resist cracking under the action of centrifugal force when rotating. Since the tensile strength of the grinding wheel is lower than the compressive or bending strength, only the tensile strength of the grinding wheel is usually determined, and the size thereof is mainly determined by the properties and amount of the bonding agent, the molding density, and the baking temperature. When the tangential stress generated by the grinding wheel along the aperture reaches its own critical tensile strength due to the high-speed rotation, cut off disc for stainless steelthe grinding wheel will rupture, and the slewing speed at this time is called the rupture speed of the grinding wheel. * The breaking speed should be 1.8 to 2 times the working speed allowed by the grinding wheel. In order to ensure the safe working of the grinding wheel, the grinding wheel must pass the rotation test. Resin cutting sheet manufacturers Shunfei grinding wheel, operating resin cutting sheet model is complete, understand the specifications of resin cutting sheet, understand the use of resin cutting sheet, please consult Yongkang resin cutting sheet manufacturers Shunfei grinding wheel. The test speed shall be 1.5 to 1.6 times the allowable working speed of the grinding wheel. For ease of use, the grinding wheel only marks the permissible* working speed (rev/min or m/s). The grinding wheel must have safety guards when it is used.
