The Secret Of Choosing The Right Fast Working Grinding Wheel

The fast working grinding wheel is widely used in ordinary steel, stainless steel metal and non-metal sheets, and it can be divided into fiber resin cutting sheets and diamond cutting sheets according to different materials, and high-speed resin cutting sheets are also more efficient, convenient, economical, etc. The unique performance has been adopted in many industries, but there have been some problems. How do we choose the right grinding wheel? What good way is there? Share the secret of choosing the right wheel.

The first is the use of the fast working grinding wheel, depending on the occasion of the use of the cutting piece. The cutting piece can be divided into cutting and grinding according to the way of use. The performance requirements of the grinding wheel are different in different applications, so it is reasonable to choose the cutting. The film is very important. We have to choose the cutting piece according to the occasion we use, which can increase the safety factor, improve the work efficiency and reduce the cost of our use.

Although it is a small fast working grinding wheel, it has a lot of attention. In daily life and work, we must strictly follow the operating standards, otherwise it may bring serious consequences. Henan Aurora Abrasive Tool Co., Ltd., a major Engaged in Zhengzhou cutting film, polishing film production and sales of professional manufacturers, we use advanced cutting equipment, our products in strict accordance with operating standards, product quality has been recognized by the majority of consumers, is your intimate partner.

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.
