LUBRICANTS FOR HIGH-PERFORMANCE GRINDING

An important aspect for the use of the cooling lubricant at high-performance grinding is the immediate and careful filtration of the grinded abrasive particles. At HEDG grinding with a removal rate Qw = 100mm²/s, a volume of 60 cm 3 is machined. This volume corresponds to a particle number of approximately 30 billion with a medium particle size of 25 µm.

Interferences on the cooling lubricant supply during

A proper nozzle supplies the cooling lubricant to the cutting point at any time during the grinding process. This can be done directly, by drawing the jet of cooling lubricant onto the cutting point, or indirectly, by supplying the cooling lubricant to the free pore spaces of the grinding wheel.
