Diamond Tool Description

A diamond tool is a cutting tool with diamond grains fixed on the functional parts of the tool via a bonding material or another method. As diamond is a super-hard material, diamond tools have many advantages as compared with tools made with common abrasives such as corundum and silicon carbide, such as High efficiency, High wear resistance, Long lifespan, Long dressing period and Low comprehensive cost. If categorized by use, there are diamond grinding tools, diamond cutting tools (e.g., diamond coated twist drill bits), diamond drilling tools, diamond sawing tools (e.g., diamond saw blades), diamond drawing dies, etc.[1]

Powder metallurgy diamond tools are widely used for machining natural stones and other difficult to cut materials, such as reinforced concrete or asphalt. In order to maintain the highest productivity of the tool at the lowest cost, the tool composition has to be properly adjusted to the workpiece properties and operating conditions. A well-engineered matrix must hold the diamonds firmly and wear at a rate fast enough to discard degraded diamond grits in order to keep the tool sharp and ensure its long service. The wear resistance of the metallic matrix can be easily changed by adding soft or hard components to the powder mixture.[2]

Diamond Tool Applications

Diamond tools are used in the following domains:

• Geological or project exploration: Diamond geological drill bits, diamond oil drill bits and diamond thin-wall drill bits are often used. The main application of PCD drilling bits is in the oil and natural gas industries and the mining industry.
• Stone processing: Diamond circular saw blades, diamond gang saws, diamond band saws are used to saw marble, granite and other stone blocks. Diamond wire saws are used in stone quarries to exploit raw stone blocks. Shaped diamond tools are used to process stone to a particular shape. Resin-bonded diamond polishing pads are used to polish stone.
• Construction: Medium or small sized diamond saw blades, diamond core drill bits and some diamond grinding or polishing tools are often used in repairing roads, remodeling buildings, and processing building materials.
• Woodworking: Composite laminate flooring is widely used. It is wearable as stone. PCD circular saw blades, profiling cutter, twist drill bits and other diamond tools are used in its processing.
• Auto spare parts processing: PCD and PCBN cutting tools are used to meet the high efficiency and low deviation processing requirements in this domain.
• IT and home appliance products processing: High-precision super-thin diamond cutting wheels are used to cut silicon slices. Resin-bonded diamond grinding wheels are used to process ceramics in optical fiber industry.
• Engineering ceramics processing: Engineering ceramics are widely used in many industries. They have the properties of high toughness, high hardness, high-temperature resistance. High-toughness and durable diamond grinding wheels are developed to process them.
• Carbide tools and other mechanical tools processing: Diamond tools are used to gain high processing precision and efficiency.[3]
