  • System for forming and polishing grooves in glass panels
    Patent number: 5329735
    Abstract: A system for forming a polished groove in a glass panel has separate grooving apparatus and groove polishing apparatus. The grooving apparatus has a rotating grinding unit which moves endwise along its rotary axis to form a groove. This unit has a leading tapered section and a trailing cylindrical section containing a finer abrasive than the abrasive in the leading section. The formed groove has an arcuate transverse profile with a radius determined by the radius of the trailing section. The polishing apparatus has a rotating and oscillating buffing cylinder with a pile surface layer which is brought into engagement with the surface of the groove while wetted with a polishing liquid. The radius of the buffing cylinder approximates the radius of the groove profile.
