Abstract

The grooves are made by a grinding machine fitted with a swivel arm, and one end of the arm carries a motor-driven grinding disc. The disc is lowered by a specific amt. starting from the surface of the glass object to grind a groove with a specified depth; and the moment when the disc comes into contact with the surface of the object is determined by monitoring the change in r.p.m., and/or the power fed to the motor driving the disc, when such contact occurs. The glass is pref. ground with a prescribed grinding pressure applied for a prescribed time starting from the change in r.p.m. or power of the motor driving disc; and the pref. machine includes all the devices necessary for the process. Ground grooves of uniform depth can be obtd. despite variations in tolerance of the dia. or wall thickness of the object.
