Use of grinding wheel made in China

The grinding wheel made in China has a series of excellent performances and is widely used. The use is still expanding with the passage of time. The main uses are as follows:

1. Cutting tools: Carbide grinding wheels can be used as a variety of cutting tools. The amount of cemented carbide grinding wheel used in China's cutting tools accounts for about one-third of the total cemented carbide grinding wheel output, of which about 78% is used for welding tools and about 22% is used for indexable tools. The carbide grinding wheel for CNC tools only accounts for about 20% of the carbide grinding wheel for indexable tools. In addition, there are solid carbide grinding wheel drills, solid carbide grinding wheel small garden saw blades, and hard alloy grinding wheels. And other cutting tools.
2. Geological mining tools: Geological mining tools are also a major use of cemented carbide grinding wheels made in China.
3. Self-sharpness, low heat generation during grinding, not easy to block, reducing the phenomenon of work burns during grinding.

The problems that should be paid attention to when using the 4.5 inches grinding wheel

The problems that should be paid attention to when using the 4.5 inches grinding wheel:

1. Resin grinding wheel should be inspected before installing the fan to see if there is any crack and use a wooden hammer to strike the grinding wheel to hear if there is abnormal sound. If there is, the cooling fan cannot be used, so as to avoid the damage caused by the grinding wheel.
2. For new or alternate use of resin 4.5 inches grinding wheel, it should be idle for more than one minute before use. If everything is normal, it can be used according to the safety regulations of grinding machinery.
3. Since the resin grinding wheel is brittle and fragile, please do not let it be impacted, collided, or fall. Store it with anti-freeze and moisture-proof. Keep the room cool and ventilated, place it flat, stack it neatly, pay attention to dustproof, keep the unused grinding wheel clean, and do not press it.
4. When installing the resin grinding wheel, the center of the resin 4.5 inches grinding wheel must be found. At the same time, the flange should be fastened. After installing the flange, the outer circle of the grinding wheel should be checked whether it is concentric with the main shaft. The resin grinding wheel has at least one side perpendicular to the center line of the main shaft.
5. After installing the resin grinding wheel, for safety reasons, please do not install the qualified protective cover before starting the machine.

Resin high quality 9'' grinding wheel - the reason for softening

When it comes to the high quality 9'' grinding wheel, it is mainly used for precision cutting and slotting of precision components such as semiconductor packaging materials, optical glass, quartz glass, ceramic materials, etc. It has sharp cutting and flexible bonding agent, which can improve the quality of processing surface and high precision. The characteristics of small slits, wide application range, can be applied to various materials processing. Next, the high quality 9'' grinding wheel ultra-thin manufacturers analyze the causes of hardening caused by resin cutting wheel film?

1. The hardening temperature is low, or too high: mainly when the temperature and humidity suddenly change greatly, and the fluctuation of the relevant technical indicators of the raw materials simultaneously reaches the conditions required for the resin high quality 9'' grinding wheel. The hardening is low, which refers to the environment and raw materials. Double impact, when the season alternates or the temperature and humidity change significantly, the highest hardening temperature of the resin high quality 9'' grinding wheel should be provided in time. The hardening is high, which means that the hardening curve has been adjusted, but when the stability is happy, the weather is dry and not lowered in time. Hardening is stable, it is also easy to cause the grinding wheel film.

2. The time of the hardening curve is short: this mainly means that under certain conditions, the low-temperature drying time of the hardening curve is short, and the heating rate is too fast in the heating stage.
3. The furnace or the kiln is too urgent or the temperature difference is too large: due to the resin high quality 9'' grinding wheel, especially the grinding wheel with large diameter, there should be a certain cooling period at the end of the hardening and heat preservation to meet the uniform release of the stress of the resin cutting wheel; If the temperature is too high or the temperature difference changes too much, the cooling changes of the grinding wheel will not be synchronized, so the deformation of the high quality 9'' grinding wheel will appear.

4. Hardening furnace kiln eliminates hardening humid atmosphere problem: All hardening furnaces, whether box furnace or tunnel kiln, must consider intake and exhaust when designing the kiln. Due to the large amount of exhaust gas released during the hardening of the resin grinding wheel ( Mainly only ammonia gas, water vapor), if these exhaust gases can not be discharged in time, it will be re-adsorbed by the pores of the resin grinding wheel during the cooling process of the high quality 9'' grinding wheel, so the grinding wheel will be smelly and soft.

Of course, there are many reasons for the resin cutting of the grinding wheel film, such as the weather and the environment, the unreasonable design of the high quality 9'' grinding wheel, the large fluctuation range of the raw materials and the uneven organization of the grinding wheel during the forming, etc., all of which require us to pay attention when producing the grinding wheel.

Specialty Of The High Efficient Metal Abrasive Disc

The high efficient metal abrasive disc is a tool that is often used by technicians. For some steels that need to be processed and processed, grinding discs are used. The quality of the high efficient metal abrasive disc has an impact on the accuracy and speed of cutting. There are many types of grinding discs on the market. The role of different grinding discs is different. Let me introduce you to the four special features of the grinding disc:

1. The self-sharpness of the high efficient metal abrasive disc is good and the cutting efficiency is high.
2. Good safety performance and high impact strength.
3. The long service life of the high efficient metal abrasive disc can save time for replacing the cutting piece.
4. The sharp and non-burning workpiece, high hardness, can cut high hardness products.

We all know that there are many kinds of high efficient metal abrasive discs, such as resin grinding discs, diamond grinding discs, etc., diamond cutting discs are also called stainless steel special cutting sheets.

If you want to know more about the high efficient metal abrasive disc, you can pay attention to Henan Aurora Abrasive Tool Co., Ltd., we specialize in the production and operation of grinding discs and grinding discs.
