2012-3-19It only takes a few minutes on the grinding machine I built for the job. Here is the super simple grinding machine I built to true up the edges of the blanks. It is just an angle grinder with a masonry wheel mounted on the edge of a table. I also mounted a lazy-susan bearing on a piece of plastic between fixed guides.

2003-6-3grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.

Theres a lot of glass to remove on this deep mirror 12.5 F1.7 cassegrain. I start with number 80 abrasive on my fixed post grinding machine. This is a coarse high-speed process designed to grind out a lot of glass really quickly. Later steps will refine the shape with finer abrasives and slower techniques.

It is essential that the mirror be run in true horizontal on the table. The track is lowered gradually parallel to the mirror surface. In the beginning of the grinding the tool is moved to one end of the track and fastened to the post to allow the edge of the tool to hit the mirror blank a little over the center.

To improve the accurate and sufficient recognition of abnormal points on the workpiece, a multidimensional anomaly point identification approach based on an improved eigenvalue method is proposed in this paper. Whether a point is normal or not depends on the angle between the two adjacent vectors which consisted of four adjacent points around the current focus.
