Grinding burn - Preventing and Monitoring! – grindaix

An adequate supply of cooling lubricant is important to prevent grinding burn during the grinding process. Grinding burn is preventable by using a coolant jet stream with 30-50% of the circumferential speed of the grinding wheel. Needle nozzles (pdf) by Grindaix apply this and efficiently prevent grinding burn on ground parts.
