The machines were produced by a variety of manufacturers over the years and have become the workhorses of the tool grinding industry. But with the advent of just-in-time deliveries, complicated flute profiles, and a shortage of skilled help, many tool manufacturers have turned to CNC (Computer Numerical Control) for a solution.
Flute grinding is a most demanding and time-consuming operation, owing to the high stock removal– a cutting depth of 7-8 mm is not unusual. The large contact area makes it difficult for the coolant to reach the grinding zone; thus, excessive heat is generated which could cause damage to the work piece surface and/or reduce the particle
