The contour grinding machine (Moore Nanotech AG150) used in this investigation is capable of producing surfaces with less than 1 μm figure error and 100 Å RMS surface roughness. A two-step process is usually used to produce each surface. First, a medium tool having 10–20 μm diamond grits is used to remove bulk material.

A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding.It is a type of machining using an abrasive wheel as the cutting tool.Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface …

In the manufacturing processes of glass and ceramics components, grinding is a key technique for curvature generation (CG) of optical surface. However, dimension errors and sub-surface damage (SSD) of components occur during the CG process. High material removal rates during the CG leads to deeper SSD on optical surface.

Bound abrasive grinding of optical materials with CNC (Computer Numerical Control) machining equipment can achieve precise control over product configuration. However, optimization of the process and its effective use in difficult grinding situations requires improved understanding of the behavior and role of grinding tools. In this document, research directed …

Chatter that limits ground surface finish has been observed in the deterministic microgrinding of brittle optical materials. In this article, the classical single degree of freedom model for chatter, accounting for both work and tool regenerative effects, is adapted for contour grinding optical surfaces.

Grinding is considered to be a rough machining process in the field of optics; a polishing process must follow the grinding process for getting optical-quality surfaces. An ultraprecision surface grinder with hydrostatic oil bearings and a glass-ceramic spindle of extremely low thermal expansion was developed to get smooth optical surfaces without any polishing process.
