Blog #fast 9'' grinding wheel

Side grinding problem

In the daily use of the grinder, we often find that some operators do not divide the type of grinder, regardless of the type of fast 9” grinding wheel, and use the side of the grinding wheel to grind it arbitrarily. This is a serious violation of the safety operation rules. behavior. According to the regulations, the grinding wheel with the circumferential surface as the working surface should not be grounded. The radial strength of the grinding wheel made in China is large and the axial strength is very small. When the operator is too strong, the grinding wheel will be broken and even hurt. In practice This behavior should be prohibited during use.

Positive operation problem

In daily use, many operators are always accustomed to working on the grinding wheel made in China because the direction can be used. In fact, this behavior is a special prohibition in the operation of the grinder. According to the operating procedure, when grinding the workpiece with a grinder, the operator should stand on the side of the fast 9” grinding wheel and must not operate on the front side of the grinding wheel to avoid the grinding wheel flying out or the grinding wheel breaking out and injuring people when the grinding wheel fails.

Hard operation problem

In the use of grinders, some operators, especially younger operators, are trying to grind quickly and use too much force, which is a very unsafe operation. The flatness of any grinding wheel made in China has a certain strength, which is likely to cause the fast 9” grinding wheel to break, or even fly out and hurt people, it is also a behavior that should be prohibited.

The fast 9'' grinding wheel is mainly divided into a resin grinding wheel, a diamond grinding wheel and a stainless steel grinding wheel. Today we mainly talk about the characteristics of diamond grinding wheels, including diamond abrasives, particle size, concentration, binder and shape size.

Use of the fast 9'' grinding wheel

Due to the unique characteristics of diamond abrasives (high hardness, high compressive strength and good wear resistance), diamond grinding wheels are an ideal tool for grinding hard and brittle materials and hard alloys in grinding.

The fast 9'' grinding wheel not only has high efficiency, high precision, good roughness, low grinding wheel consumption, long service life, and can also improve working conditions. Therefore, it is widely used in low-iron content metal and non-metal hard and brittle materials which are difficult to process with ordinary grinding wheels.

If you are interested in the knowledge of the grinding wheel, you can continue to pay attention to us. You can also send us a message and look forward to hearing from you.

The working layer of the resin diamond cup type fast 9'' grinding wheel is composed of a diamond and a resin binder. The main component of the resin binder is a resin and an auxiliary material, which is mixed with the diamond powder, and is heated and solidified by pressure to form a resin diamond grinding wheel which is firmly combined with the substrate.

Diamond grinding wheels are superhard abrasives, which are generally used to process high hardness and high brittle materials such as hard alloys, ceramics, glass, semiconductor materials and stone.

The advantages of the diamond cup type grinding wheel produced by our company are as follows:

a. Strong grinding ability, good wear resistance, high durability, easy to control the processing size and automatic processing.

b. Small grinding force, low grinding temperature, good surface quality, no burns, cracks and tissue changes. When the diamond wheel grinds the cemented carbide, the grinding force is only 1/4~1/5 of the green silicon carbide grinding wheel.

c. High grinding efficiency. When machining hard alloys and non-metallic hard and brittle materials, the metal removal rate of diamond grinding wheels is better than cubic boron nitride grinding wheels; but when processing heat-resistant steel, titanium balance, mold steel, etc., cubic boron nitride grinding wheels are far higher For diamond grinding wheels.

d. Low processing costs. Diamond grinding wheels and cubic boron nitride grinding wheels are relatively expensive, but because of their long life and high processing efficiency, the overall cost is low.

fast 9'' grinding wheel

In recent years, the development of the fast 9'' grinding wheel has become faster and faster. In particular, the use of resin grinding discs is more extensive. The fundamental reason is that it is inseparable from the unique properties of resin grinding discs. Because the resin grinding discs have High bonding strength, can be used at higher speeds, can withstand large grinding pressure, and is widely used in the burr and rough grinding of steel and foundry industries. So, today, talk about resin grinding wheel cutting What to pay attention to when replacing a piece.

1. Resin fast 9'' grinding wheel wear: Any grinding wheel cutting piece has its own wear requirement. If the wear condition reaches a certain level, it must be replaced with a new one. It cannot be used for saving materials, and it is extremely unsafe. Behavior. Generally, when the resin grinding wheel is worn to a diameter 10 mm larger than the diameter of the chuck, it should be replaced with a new one.

2. The fast 9'' grinding wheel validity: The new grinding wheel from the warehouse is not necessarily qualified. Even the new one from the manufacturer is not necessarily qualified. Any grinding wheel cutting piece has a certain effective period and is used within the effective period. It is Qualified; if it is used beyond the expiration date, it is not necessarily qualified.

3. The fast 9'' grinding wheel texture: the use process, if the grinding wheel appears locally cracked, should immediately stop using, replace the new grinding wheel cutting piece, so as not to cause the grinding wheel cutting piece broken and injured.

The above is what you should pay attention to today for the replacement of the resin grinding wheel cutting piece. If you want to know more details, please contact us! We will be happy to help you! Tel: +86 15617985439.

For the fast 9'' grinding wheel, it should be familiar to the professionals. After all, it is something that is often in contact. But it is unclear to those who do not touch this aspect. It belongs to the fast 9'' grinding wheel, made of abrasive and binder resin. It is widely used in ordinary steel, stainless steel, 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 and convenient. The economy and other unique features have been adopted in many industries, but there have been some problems. How do we choose the right cutting piece, what good way is there? Then choose the right cutting piece to cut the piece by the grinding wheel. Manufacturers elaborate.

The first is the use of the fast 9'' grinding wheel. It is selected according to the occasion of the grinding wheel. The grinding wheel can be divided into cutting and grinding according to the way of use. Most of the cutting machine is fixed mobile, and the power of the machine has high power and low power, the cutting speed will also have high-speed cutting and ordinary cutting. In addition, cutting materials are varied, such as stainless steel, titanium alloy, ordinary steel, viscous metal, high carbon steel, non-metal, etc., the performance requirements of the fast 9'' grinding wheel are different in different occasions, so it is very important to choose a grinding wheel reasonably. We should choose the cutting piece according to the occasion of its own use so that it can increase Safety factor, improve work efficiency, reduce our use cost. For ordinary machine, when selecting the fast 9'' grinding wheel, the grinding wheel on the cutting machine usually refers to the fixed cutting table, common The cutting machine usually cuts workpieces with a diameter of less than 50mm, but because the cutting power is small in order to reduce the radial frictional resistance, we usually choose a cutting piece with a thickness of 3.2mm, so that the grinding wheel is thinner and also has a certain elasticity, it will feel sharper when cutting.

In our daily life and work, it is necessary to strictly select the fast 9'' grinding wheel according to the operating standards, otherwise it may bring serious consequences. Zhengzhou Shuangling Abrasives Co., Ltd., a professional manufacturer mainly engaged in the production and sales of grinding wheels and grinding discs, we Using the most advanced cutting instruments, our products are strictly in accordance with the operating standards, the quality of the products has been recognized by the majority of consumers, is your most intimate partner.
