How was the diamond blade made?

diamond cutting blade

If you can only cut a diamond with a diamond, how was the first diamond blade made? Or like the first diamond cutting tool.

Diamonds can be cut. They can also be cleaved, which is what you sometimes see in movies, where someone puts an edged doohickey against a diamond and taps it with a hammer. The diamond has a regular structure inside of it, sort of like the scaffolding of a building. A knowledgeable person can determine where the planes are, and make use of them.

A diamond blade having a cutting section consisting of diamond abrasive grains and attached to the outer peripheral edge of a substrate in order to decrease the wear of the under-head region of a cutting diamond blade, characterized in that at least either the front or the back of the substrate is provided with an island-shaped cutting section separated from the first-mentioned cutting section, an extended cutting section extending toward the center of the substrate or an approximately U-shaped profiled cutting section. Also a method of producing diamond blades, characterized by simultaneously performing the sintering of the cutting section and the binding of it with the substrate.

The natural diamond crystal is not always big, we can call the small diamond crystal as diamond powder, they can be mixed with other metal powder to compose diamond segments, diamond segments are welded on blank core blade, then one new diamond blade is made, you can use this diamond blade to cut diamonds.

Another, do you know there is a word called "artifical"? People can make artifical diamond now! Most of the diamond tools are made from artifical diamond crystal nowadays.

No, it is not just diamond that can cut diamond. An ordinary steel saw will cut diamond. It's just that the diamond cuts back. If you cut 1 cm into a diamond, then you might have to use up 100 cm of steel.

How to make pig feed pellets

3 steps creating your own pig feed 1. after you area unit attending to build pig feed pellets on your own, the primary step is to form certain the wetness of your raw materials is concerning 10-12%. The wetter or appliance material can have an effect on the ultimate quality of finished pellets. you'll be able to use a drier, so you'll be able to get the perfect wetness quickly. otherwise you will dry it naturally within the sun. 2. the second step you've got to try to to is crushing your materials before you begin creating your own pig feed pellet pellets, if your raw materials size is just too abundant massive, it is not really easy to be ironed into pellets. after you crush it to fine powders, the finest, the better, the pelletizing rate and final pellets quality are going to be higher. 3. feeding your raw materials into the pig feed pellet mill machine through the feeder. they will be compressed to columnlike holes on the die and discharged from the machi...

Types of Concrete Cutting Blades and Their Usability!

concrete cutting blades In commercial and residential construction projects, use of the concrete blades is growing rapidly. The main advantage of concrete cutting blades is that they can be used for different applications such as sidewalk pavers, patios pavers and walkway pavers, project entrances, pavers for driveways, and walkway through a city park, pool deck and playgrounds. There are some valuable tips given below that will ignite your knowledge about concrete cutting blades. Cutting Efficiency of blades: The concrete cutting blade ability is usually expressed as how much area the concrete blade can cut in unit time. This ability indicates the sharpness of the cutting blade. The cutting blade may be sharp and keen but it may have been dulled by continuously use it. If the blade teeth are worn thin from long use then the blade isn’t strong enough to stand the strain of maximum speed of the concrete cutting machine. The blade sharpness must match the machine operator's c...

What specific steel is commonly used for the core of 14" dia. concrete diamond blades?

concrete diamond blade A diamond blade may be composed of a steel core and powder metal which is combined with diamond crystals and then heated and pressed into a molding which form the diamond segments, also known as the "cutting teeth" of the blade. The diamond segments are then welded to the steel core. Alternate methods of manufacturing diamond blades include electroplating diamond crystal directly to a metal core, often a steel core, but occasionally other metals as well. And to a lesser extent, brazing is used to create single layer diamond blades. The method of adhering the diamond crystal will depend on the application intended. The steel core can vary in design. Some of them have spaces (known as gullets) between each segment to provide cooling and slurry removal, while others have a single continuous rim for smoother chip-free cutting. The type of core that has to be used depends of the type of materials that will be cut. Due to different compound of concrete, su...
