Retrieved from ” https: Even with the relatively high volume of optical components manufactured using the SPDT process, this process cannot be classified as macjinability production, especially when compared with production of polished optics.


A diamond-tipped lathe tool is used in the final stages of the manufacturing process to achieve sub- nanometer level surface finishes and sub- micrometer form accuracies. Kinematic system and operations of drilling machines.

Machinabilit Glass production Machining. If it is not detected immediately, even a minute error during any of the cutting stages results in a defective part. The extremely high requirements for quality of diamond-turned optics leave virtually no room for error. You have to be logged in before you can add this course to your SpeedyCourse calendar.

Construction, working principle and applications of shaping, planing and slotting machines. The SPDT manufacturing process produces a relatively high percentage of defective parts, which must be discarded.
