Diamond pellet grinding is used for fine grinding and lapping optical surfaces such as lenses, mirrors and prisms.
Diamond pellet grinding is regarded as a highly efficient method for mass producing optical parts, because unlike the more traditional loose abrasive grinding method, diamond pellet grinding can quickly shape surfaces for the smoothing process.
Advantages of diamond impregnated lapping pellets
Shorter cycle times
Higher removal rates
Faster polishing cycles
Less machine maintenance
No need to purchase abrasive powder
Choosing a diamond impregnated lapping pellet
GAASH designs and supplies highly-specialized diamond impregnated lapping pellets for creating and polishing optical glass and high precision surfaces. When selecting diamond pellets, it is important to know how much pressure can be applied to the pellet surface. Choose diamond pellets that will maintain an accurate and consistent dimensional grinding distance at the radius direction of the workpiece surface. The matrix, hardness, layout, and grinding distance in each pellet should also be taken into consideration.
In addition, GAASH can further provide specialized optical solutions for a broad range of custom made instruments with unique requirements.
