Development Of Highperformance Cbn And Diamond

178 new diamond and frontier carbon technology, vol. 15, no. 4 (2005) effective highspeed grinding. there are many cbn vitrified bond wheels used in highspeed grinding. these wheels enable truing and dressing simultaneously with a diamond tool called a rotary dresser.

A process for truing a resin bonded, diamond grinding wheel utilizing a molybdenum tool as the truing or dressing tool. the molybdenum tool is held in frictional contact with the peripheral work surface of the diamond grinding wheel as it rotates on a spindle, with the molybdenum tool either being stationary, or movable through a predetermined path to form a work surface of particular shape on.

Us5058562a Rotary Diamond Tool For Truing Grinding Wheel

A rotary diamond tool for truing a grinding wheel, comprising one or two circular vapordeposited base plates each having a thin diamond layer formed by a vapor deposition process such as electron assisted chemical vapor deposition or direct current plasma chemical vapor deposition. the diamond truing tool is further provided with a pair of backup plates brazed on both side surfaces of the one.

A truing technique that can be used to shape the tip of an electroformed diamond tool into a hemisphere and flatten diamond grains on the tool working surface at the same level as the bond face was developed. a polycrystalline diamond disk whose top surface roughened by electrical discharge machining was partially flattened by grinding was used as a truer.

An electroformed diamond tool with a tool tip radius of 0.2 mm was developed to achieve a surface roughness of less than 10 nm rz on a mould made of cemented carbide. a polycrystalline diamond disc with a primary grain size of 0.5 m and a diameter of 15 mm was used as a truer. a concentric guide groove with a reverse profile relative to the hemispherical tool and a surface roughness of 0.5.

Anglestyle precision truing cleaners for toolroom grinding wheels mount these truing cleaners to a tslot to reshape worn diamond and cbn grinding wheels. cleaners have an angled wheel for truing 100grit and finer grinding wheels.

Wheel, creating a sudden change in the truing force. for the rod diamond blade tool, a similar wear process occurs. instead of the fracture and pullingout of diamond grits, the diamond rod fractures, exposing a sharp contact point for truing the grinding wheel. truing force data and sem micrographs are used to study the wear mechanism of the.
