Polycrystalline Diamond (PCD) is a new type of superhard material that has been researched and used internationally since the 1970s. It is formed by sintering at a high temperature of 1400°C and a hig...
The cutting tools grades and specifications are improperly selected, such as the thickness of the blade is too thin or the grades that are too hard and brittle are selected for rough machining.
In the metal cutting process, cutting force is an important physical quantity, and surface roughness is one of the important indicators to measure the quality of processing.
The design of the cylinder head is the key to reducing fuel emissions and meeting stringent government regulations. The valve seat hole of the valve guide on the cylinder head part is a key hole
Judging from the used PDC drill bits, the main characteristics of most PDC bit damage are the fracture of the tooth column, the fragmentation of the composite sheet, the chipping
According to its manufacturing process, PCBN is divided into CBN directly combined into a sintered block through high temperature and high pressure, or sintered at high temperature and high pressure w...
Polycrystalline diamond (PCD) composite is a kind of composite material in which the thin layer of PCD is adhered to the cemented carbide substrate.
Customers use ceramic diamond cylindrical grinding wheels to grind PCD roller tools. At first, the customer was not satisfied with the chipping effect of using a domestic brand grinding wheel. Currently, customers use a resin diamond grinding wheel from a certain European brand to achieve better grinding results, but the cost is relatively high.
A diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool that uses electroplating or powder metallurgy methods to inlay a large number of diamond particles on the surface of a steel roller. It is used for special machine tools and gear grinders for mass form grinding. Rotating at a certain speed (thereby reducing the relative speed between the roller and the grinding wheel) produces grinding and rolling effects on the surface of the high-speed rotating grinding wheel, so that the grinding wheel obtains a sharp working surface that matches the roller profile.
