Maintaining an edger

According to suppliers and glass shop owners, edging machines are the most common type of equipment a shop will have.

Bob Spears, director of machinery sales for Salem Distributing, Winston-Salem, N.C., says edging and beveling equipment require the greatest amount of maintenance. “Constant exposure to water [coolant], polish slurries and glass particles create a hostile environment for any metal elements as well as moving parts,” Spears says.

John A. Czopek, brand manager of machinery sales for the Sommer and Maca Machinery Division of C.R. Laurence Co., Los Angeles, says there are several general steps to edger maintenance:

  • Change the coolant regularly, “at least once a week to help prevent growth of organics,” Czopek says.
  • Clean the grinding wheel with a dressing stone that “cleans the working area of the wheel and exposes fresh diamond edges to improve cutting.”
  • Occasionally change the conveyors’ glass clamping guide system. “They will slowly become permeated with glass grinds, creating a system that does not grip glass well.”
  • In addition, operators or managers should be sure to perform other general maintenance, including lubrication and cleaning of the machine’s mechanical components according to the manufacturer’s recommendation.
