Optical Profile grinding is employed to grind various precision moulds such as die & punch for press which have complicated forms of irregular lines and curves, forming cutting tools, cutting tools, high precision plate gauge, electrode for electric discharge grinding and formed precision parts such as template.
Structurally optical profile grinding wheels are used in dry, which is a big feature and handled by manual system as well as Numerical Control full automatic system. Lately NC machines are widely employed in various industries and increasing rapidly. Rigidity, horsepower and machining accuracy of latest machines have been much improved where optical profile grinding wheels are required more under this condition to generate high precision machining.
Optical profile grinding wheel is used for precise grinding mould and die, punch pin, optical grinding and form grinding cutting tool ( such as end mill and reamer) and precise instrument
The Workpiece Materials
► Diamond: Super hard and brittle cutting materials (such as tungsten carbide, cermets, ceramic, etc)
► CBN: heat treated steel (such as SKH, SKD and SKS, etc)
The abrasive grits of profile grinding wheels
| Diamond | For grinding hard materials such as tungsten carbide, cermet, ceramics. |
| CBN | For grinding ferrous materials such as SKH, SKD, SKS, SUS & Etc |
| Concentration（100, 125, 150） | In general we recommend you to choose concentration at 100 or more. |
