Why Choose Diamond Tools For All Your Stone Cutting Applications
It goes without saying that stone is a very hard material and can wreak havoc on any tools that are used to cut it. Knowing the hardness grades ahead of time can pay dividends in the longevity of your tools. The most popular type of tool for stone fabrication is a diamond tool.
A diamond cutting tool is one where grains of diamond are fixed on the contact surfaces of a tool through methods such as material bonding. Diamonds are a super hard compound and this is why diamond cutting tools have advantages over other types of abrasives.
The Advantages Of Diamond Tools
The hardest material found on this earth is a diamond. This hardness coupled with high strength, low friction and above average wear resistance is why diamonds make excellent abrasives. Diamonds are known for their high grinding efficiency while requiring less force. This means the grinding process will generate much less heat meaning cracks or burns avoided and wear on your tools is decreased. As you begin grinding, a diamond tool will keep it’s shape and dimensions much better than other abrasives. This allows for detailed, quality grinding work. Efficiency is increased through the use of diamond because of the increased lifespan of tools. There is no time or extra cost to change out bits or discs and relates to a lower per piece cost.
Types Of Diamond Tools
High-temp Brazed Diamond Tools: created by brazing a layer of diamond onto the tools surface by soldering. This is a new type of diamond tool and has advantages because the solder attaches the diamonds very securely and allows for regularly arranged diamonds.
PCD or Polycrystalline Diamond: micro size diamond crystals are sintered at high pressure and temperature creating a tool with good thermal stability and fracture toughness, A use for these types of tools is in geological drills.
Ceramic Bonded Tools: glass or ceramic powder are the most common bonding materials used and makes for a tool that has little elastic deformation and good chemical stability. One drawback however is that brittleness levels are elevated.
Resin Bonding Diamond Tools: Resin powder is used to bond the diamonds to the tool surface and is the most common form of polishing pad in the industry.
Plated Diamond Tools: electroplating adheres the diamonds to the tools. Precision is the number one advantage to this type of tool.
Metal Bonded Diamond Tools: Metal mix powder bonds the diamonds in this case. The metal mix is not functional, only the diamonds are. Commonly used in saw blades, diamond cored drill bits, grinding cups and so forth. There are varying levels of bonding mixture and this is specified by the hardness of the material that is to be cut or ground. The mixture and the amount of heat and pressure applied while bonding dictate the hardness of the tool.
Diamond tools can be used to process:
- Aluminum, all copper alloys, rubber or resin and other non-ferrous metals
- Carbide alloys
- Stone, glass, concrete, ceramics, asphalt, semi conductor type materials and gem stone.
- Many steels are not suitable for some metals as diamonds may react with the high temperatures that the grinding process can generate.
Diamond tools are the number one grinding method used in most stone fabrication and can offer great bang for your buck and increase productivity on your job site.
