Comparison of materials for use in the precision grinding Precision grinding of optical components is becoming an accepted practice for rapidly and deterministically fabrication optical surface to final or near-final surface finish and figure. In this paper, a comparison of grinding techniques and materials is performed. Flat and spherical surfaces were ground in three different substrate materials: BK7 glass, chemical vapor deposited silicon carbide APOMA – American Precision Optics Manufacturing Association02.04.2022 · Optical, electro-optical and photonic materials require extreme precision during machining, finishing and cleaning operations. The critical processes of grinding, drilling, coring, sawing/wire sawing, lapping, polishing, CMP (Chemo-Mechanical Polishing/Planarizing), in and post-process cleaning, ultimately have a major impact on component performance. Grinding and Polishing Guide | BuehlerGrinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel.

Double-Sided Grinding & Polishing - Sydor OpticsDouble-sided grinding and polishing, also known as double-sided lapping and polishing is performed with particles suspended in a liquid vehicle to abrade parts equally from both surfaces. The process produces a relatively stress-free environment that induces minimal thermal distortion making it compatible with most optical materials. The double-sided manufacturing process uses planetary action MZI SpindleI highly recommend MZI Precision! They offer outstanding service, coupled with unparalleled expertise and excellent communication. When my Haas VF2 spindle showed run out, I called MZI Precision to see if they could help. I wanted the spindle checked out in the machine. They came to my shop, performed some tests, and determined that my slight crash damaged the spindle. Not only were they here

In fact, they are machining to most people.However, the ability to do precision centerless grinding in addition to machining is a definite advantage.. How does centerless grinding work? Centerless grinding is one of several machining processes that use abrasive cutting to remove material from a part (workpiece). Production of precision optics using laser micro- machiningMicro-Optic Precision Molding Precision molding is well suited to low cost and high reproducibility for large and medium quantities. The foundation of the technique is the micro-machining process described earlier. Heat and pressure are applied to a glass "gob" to create a shape in the form of the mold.
