Researchers at Fraunhofer IPA have developed a procedure for internally cooling disc-shaped, rotating cutting tools. With the support of pertinent mechanical saw and sawing tool manufacturers, the result is a lightweight, upgradable and cost-effective concept that represents a milestone in the evolution of circular saws.
When cutting materials, the temperatures rise, which negatively affects the workpiece and shortens the tool’s service life. One possibility for directing the cooling lubricant at the cutting area is internal cooling within the tool, which sees the cooling lubricant directed through internal channels in the tool directly to the cutting area.
Now, for the first time, Fraunhofer IPA has been able to integrate channels into the saw blade, meaning that internally cooled tools can be created. The idea to adapt internal tool cooling systems to include disc-shaped tools such as circular saw blades has enormous potential and has met with a great deal of interest in the industry.
