Chemetall introduces high-performance glass grinding and drilling coolants. Acecool 5679 increases glass grinding and drilling processing speeds while reducing the amount of dressings. The result is increased output of glass parts at low coolant concentrations without burning and greater tool life, according to the company. Acecool 5679 helps improve glass edge quality, which is critical for its quality and strength. This technology has proven performance at automotive and architectural glass fabrication plants in Europe and Asia.

Along with increasing the processing speeds and tool life, Acecool 5679 keeps the glass slug soft to minimize machine cleaning requirements and maintenance. This and the reduction of tool dressing increase the overall productivity of the glass grinding operation. Acecool 5679 has buffering agents which help to maintain a desired pH range to prevent skin irritation and equipment corrosion.

Acecool 5679 is biostatic and does not contain bacteria or fungicides that can be harmful to the environment and to the skin. Acecool 5679 is available in a bright yellow color that makes it easy for the operators to visually inspect the coolant in the system. Given good maintenance and handling, Acecool 5679 can have a lifetime of up to one year or more.
