With the development of science and technology and the improvement of production technology, the 

cutting blades that used to rely mainly on imports have been greatly developed, especially in the 

metal cutting blades and other chemical cutting sheet industries. With the maturity of technology 

and the improvement of technology, the production of cutting blades It is no longer a problem. 

Aurora abrasives will lead us today to understand the cold pressing process in the production of 115 

* 1 * 22 cutting disc.

Most of the original production is ceramic grinding wheels. The advantages of ceramic bond grinding 

wheels are their natural porosity and chemical stability, which makes them suitable for dry and wet 

grinding, especially in the case of water-based and oil-based grinding fluids. However, the ceramic 

grinding wheel is less elastic and requires a high sintering temperature, which limits its 

development. The phenolic resin bond grinding wheel has the advantages of good elasticity and low 

sensitivity to shock, impact and side pressure. Its high stability makes it suitable for higher 

speeds and improved grinding performance, making it particularly suitable for grinding wheels and 

Huaji cutting wheels. Its good elasticity makes it suitable for ultra-precise grinding and surface 


The production process of the phenolic resin bond grinding wheel is mainly a cold pressing process. 

How about this?

Cold pressing process: The bonding agent used in the cold pressing process is a wetting agent and a 

powdery resin. The liquid phenolic resin, furfural, decyl alcohol, cresol and the like are usually 

used as a wetting agent, and the most used liquid phenolic resin. The factors determining the 

proportion of liquid resin and powdered resin are: abrasive particle size distribution, filler type, 

filler amount, viscosity of liquid resin, properties of powdered resin, and the like. If the 

viscosity of the liquid resin is larger, more liquid resin is required to completely cover the 

surface of the abrasive; the smaller the particle size of the abrasive and the filler, the larger 

the specific surface area and the more the liquid is used; the molecular weight of the powdered 

resin is higher. The lower the high and free phenol, the worse the adhesion to the liquid resin and 

the greater the amount of liquid required. In all of the above cases, it is necessary to increase 

the liquid to powder ratio. Generally, a liquid resin is used as a wetting agent, and the ratio of 

liquid to powder is 1:2 - 1:4, and a mixture of furfural or decyl alcohol and eucalyptus oil is used 

as a wetting agent, and the ratio of liquid to liquid is 1:6 - 1:8. The mixer is process-proven to 

achieve the desired mixing and does not damage the abrasive. The mixing time after adding the fine 

powder is generally 2-4 minutes. If the mixing is too short, the mixing is not uniform, the resin 

film is too long to fall off, and the temperature of the material is raised, and the resin is pre-


From the analysis of the aurora abrasives, the cold pressing process in the production process of 

the cutting piece is the most commonly used production process. Whether it is a metal cutting piece 

or a resin cutting piece, this process is very critical. Therefore, the majority of manufacturers 

are In the process of production, we must grasp the various processes of cold pressing in the 

production process to prevent large quality problems due to a small mistake.



Bitcoin economics has not changed

YOU DON'T HAVE TO BUY A WHOLE BTC BITCOIN! Each bitcoin is equal to 100 million Satoshis, making a Satoshi the smallest unit of bitcoin currently recorded on the blockchain. Think of the Satoshi as the “cents” part of bitcoin. But unlike a penny that represents 0.01 USD, Satoshi represents roughly 0.00000001 BTC — or bitcoin to its eighth decimal.

Bitcoin forecast to 2029

Time model tends to forecast lower bound to prices. Stock-to-Flow model is a better model, click chart above to see details. It incorporates the halvings and better represents the monetary policy of Bitcoin. Hype cycles are expected around each halving as investors anticipate the price appreciation. Bitcoin has a fixed supply (maximum 21 million Bitcoins), therefore it cannot be devalued by central bank money printing (so called Quantitative Easing, QE). Bitcoin is also decentralised, meaning no single authority can control it. It has existed on the Internet for 10 years from 2009. It will be the money of the machines and Internet. Also described as digital gold due to its scarcity and high value.

This is a good short article that explains, why Bitcoin? Why Bitcoin?

Be Your Own Bank
Bitcoin (BTC) is the people's money, owned by the people for the people. Not by a bank or country. What are you waiting for?

It gives you control of your money (individual sovereignty). Preserve your savings; they will increase in value over time. Easily send money anywhere. Government's can't take it! What are you waiting for? Get a free Bitcoin wallet today or, run your own full node.

If you do not know where to start, install a Mycelium or, Electrum wallet.

Run your own Full Node and help the Bitcoin (BTC) network. Be Your Own Bank! There are currently (May 2018) about 138,000 full nodes globally. About 10,000 of these are listening for outside connections on the P2P network.

As people suddenly realise they don’t own their data on Facebook, how will they react when they realise they don't own the money in their bank accounts either?

The good news is government can't take your Bitcoin in your own full node. Not by legalised theft (inflation), nor by government bail ins. Realise that fiat money, $, €, ¥, £, yuan, Venezuelan Bolívar, Argentine Peso, Zimbabwean Dollar, etc. is crashing! In the last 100 years, all fiat currencies have lost 97-99% of their purchasing power, reducing your standard of living.


What is a Full Node?

Download Bitcoin Core

Instructions for running your Full Node of Bitcoin Core

Instructions for running your Bitcoin Full Node under Tor for anonymity, privacy and security of your money in your own bank.

With a Full Node behind the Tor network, your Full Node is difficult to trace.

You also can use a VPN for encryption of your Bitcoin transactions (can be used with or without Tor).

For VPN, the PCMAG Editor's Choice is NordVPN, click here.NordVPN

With a Bitcoin Full Node protected by VPN and / or Tor, you have complete control of your own private electronic bank. Anonymous like cash, but electronic, instant, unlimited by space time and appreciating in value.

Physical Gold


Protect yourself and family from central bank currency debasement and inflation in asset prices, housing, food. There are rising levels of financial, economic and geopolitical risk in the world. In the last 100 years, all currencies have lost 97-99% of their purchasing power. Some believe that the final move to zero will take place in the next few years.

Currency debasement through money printing is the destruction of fiat money purchasing power - $, €, ¥, £, yuan, Venezuelan Bolívar, Argentine Peso, Zimbabwean Dollar...

True inflation and cost of living is currently 8% higher than the government reports. Real wages are falling rapidly and most people are taking out more and more debt to make ends meet. Only the wealthy minority and banks benefit from the current system.

Protect yourself. Buy physical, allocated gold, silver, platinum online and store it in safe vaults outside your jurisdiction (Switzerland, UK, USA, Canada and Singapore) or, at home. Physical gold has limited supply. Buy before the panic!

Look what happened in Cyprus (2013), Greece (2015) and Spain (Catalonia 2017). The lesson is that the money in your bank account is not really yours. It can be taken or frozen by the government just when you need it. Maybe it is not a good idea to keep too much money in the bank, especially when the next financial crisis comes!
