Diamonds are more than just pretty accessories, they are also perfect for all sorts of grinding and cutting. They are strong and durable which is exactly what you need in concrete cutting tools. Diamonds have been providing cost-effective and durable solutions for the construction industry for many years now.
They can be easily manipulated in order to maximize the performance of the cutting tool.
Diamond crystals can be grown synthetically and can come in a variety of different shapes, sizes, and with different qualities. Synthetic diamonds have replaced natural ones for one main reason and that is easier manipulation. Diamonds can now be easily tailored for all sorts of different uses. The toughness of the diamond can be adjusted easily by knowing that as the size of the diamond decreases, its toughness rises.
Diamond size is typically sorted by mesh or grit size. While larger diamonds are usually used for a more aggressive removal, smaller ones are good for polishing or honing. More about different concrete saw blades, their sizes and uses you find on ugtx.com.
Diamond saw blade is made of a circular steel disk while diamonds are placed on the outer perimeter of the blade. The bond is there to hold the diamonds and it is usually made out of metal or plastic resin. However, other materials might also be used depending on the application of the tool. It’s crucial to match the material of the bond with the material that will be cut in order to prolong the life of the bond. The diamonds on the surface do all the cutting and as the blade rotates, the diamonds chip away.
At first, smaller microfractures will appear at the surface of the diamonds, followed by bigger microfractures. Eventually, the diamond crushes and pops out of the bond. The blade, however, is still cutting well as the next layer of diamonds continues the cutting. As the crystals fracture, extra cutting surface is being created which is why diamond core drill bits and saws are more effective after they’ve been used a couple of times.
The diamond and the bond are both equally important for the perfect functioning of the blade and it’s up to the manufacturer to find the perfect combination as a proper combination will provide a good support for the diamonds.
Diamonds are being embedded into saw edges through a metal bonding process that introduces heat in order to seal the crystals into place. Resin, ceramic, and electroplating methods can also be used for bonding.
Also, a higher velocity of saw blades means less noise as higher speeds produce less resonance. This is a particularly useful feature as noise damage is one of the main concerns on all construction sites.
When choosing a blade, you must consider the type of aggregate that is going to be cut. While limestone, slag, or coral aggregate are soft and aren’t difficult to cut, concrete with river gravel and flint aggregate are a bit more challenging.
You can also choose from diamond discs for angle grinders, motor saws, floor saws, table and bridge saws, and more.
