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.

- burning
burning
Rotary tool that removes hard or soft materials similar to a rotary file. A bur’s teeth, or flutes, have a negative rake.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- dressing
dressing
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
