Precision Grinding of Hard and Brittle Materials

Precision Grinding of Hard and Brittle Materials Two cup-shapedidentical size diamond-grindingwheels with metallic (D20/30 MIC­ L50M-l/4) and resinoid (SD240-RIOOB69-6mm) bonding were used. The profile of the grinding edge is circular in this case, but not restricted to this shape, thus forming a toroid. The importantfeature is that the grinding surface shape is axially symmetrical.

[PDF] Precision Grinding of Hard and Brittle

Two novel techniques were used to study the formation of ductile mode streaks during diamond grinding (primary process) of germanium, silicon, and Limestone that aid the secondary process of polishing. In the first technique asph~ric surfaces were generated on Ge and Si at conventional speeds (5000 rpm). In the second technique high speed grinding (100,000 rpm) of plano surfaces on Limestone and Si ...

Precision grinding of a microstructured surface on

01.05.2018  In this study, the precision grinding of microstructured surfaces on hard and brittle materials with a microstructured, coarse-grained diamond grinding wheel was examined. First, the method for preparing the microstructured grinding wheel was developed. The influence of laser-fabricated microstructure geometry on the form accuracy of the finally ground microstructured surfaces was analysed. Subsequently, the ductile regime grinding of microstructured surfaces on hard and brittle ...

01.01.1987  Concluding Remarks on the Hiqh-Efficiency Grindinq of Hard and Brittle Materials The grinding process of hard and brittle materials is primarily due to the micro-brittle fracture of the material. The grinding force and power can be, therefore, considerably reduced by taking advantage of this phenomenon. The brittle fracture of the material is accelerated by selecting the grinding condition

OSA Subsurface damage in precision ground

Ductile or brittle fracture mode grinding [ 6] can be used to machine brittle materials such as Zerodur ® and ULE ®. Ductile mode grinding has been reported to give low SSD [ 7 ]. However, achievable material removal rate is low, as for example the critical depth of cut is ~50 nm on Zerodur ® [ 8 ].
