PCD tools with CVD diamond tool performance comparison

Polycrystalline CVD diamond due to its structure, can produce more than the actual natural diamond fracture toughness (resistance to fracture). This feature is in

intermittent cutting and grinding wheel dressing and other offensive machining proved very useful. Generally, CVD diamond mechanical prison

Similar to solid firmness of advanced ceramics.
Separate carefully designed and manufactured a sheet of CVD diamond fracture toughness, strength, and other key properties, can be improved for CNC rotating wheel

dressing, high speed or similar dry machining aluminum and metal matrix composite materials, high-performance cutting tools .
CVD diamond tool and PCD tool manufacturing methods similar to Diamond blade are brazed tungsten carbide or high speed steel body with cut corners, and then diamond

wheel grinding tools. Thick solid brazed diamond blade technology is developed in 1990s

, This technology addresses the need for metal cutting film, diamond coating bonded carbide inserts and cutter body selected problems. The diamond coating for

machining bonded carbide inserts with blade selection has been widely considered to be a cutting

Negative impact. Most stand-alone tool for cutting thick film CVD diamond material thickness of about 0.5mm. Relatively smooth, fine particles (about 1μm) nuclei

polished surface is generally used as the cutting tool rake face; the side surface of coarse particles (> 50μm) by the vacuum

Brazed tungsten carbide or high speed steel blade body.
Despite the strict control of the CVD process is vital, but ultimately decided edge quality and robustness of the tool or tool manufacturing. Most experienced

industrial manufacturers often use for PCD grinding wheel, and in order to meet the increased hardness of the CVD diamond material, they

Extend the grinding time.
PCD recipe with CVD diamond grinding wheel, in contrast to PCD tools, grinding a CVD diamond tool edge to more than 10 percent to 20 percent of the time. However,

extending blade grinding time, can make the tool manufacturer to obtain better surface roughness of PCD tool cutting edge. Since

CVD diamond is more resistant than the PCD, so a simple way to increase the feed amount of the grinding wheel will produce an excessive CVD diamond grinding force and

damage the cutting edge.
Thick CVD diamond grinding can produce a brazed side, mirror surface roughness (Ra <0.05μm) of the cutting insert. In contrast to the film CVD diamond coating, thick

blade of the unique properties of the workpiece can also produce an excellent surface roughness. Thick

CVD diamond film is selected in the tool is also provided the opportunity to replace the single-crystal diamond cutting tool.
Independent CVD diamond material makes it strong and abrasion resistance high alumina milling machining applications such as wide an excellent choice. CVD diamond tool

life when machining aluminum alloys are often commercial PCD tool life 1.55 times. The actual improvement depends on the specific

Aluminum, cutting tool design and manufacturing technology. CVD diamond tools are often used for turning pistons, aluminum wheels for cars and other high-silicon

aluminum finishing materials and metal matrix composite materials generally require machining intermittent cutting. Although the high concentration of sialic always

CVD diamond

The object of study, however, diamond blade cutting tool machining at low aluminosilicate materials are also increasingly common. High productivity machining or

finishing all require precise use of diamond tools. A car manufacturing company conducted a finish for aluminum parts, CVD diamond

PCD cutter blade stone only durable than 30% and throughout the life of the tool can be continuous processing of the required surface roughness.
