Impact of nozzle design on grinding temperature of

2020-10-31 · Grinding also known as finishing operation is an important machining operation to obtain good surface quality, better dimensional accuracy for hardened materials. But it is a matter of fact that grinding temperature is usually high because of i) higher cutting speed ii) intense interactions between abrasive grains and the work piece . Such high temperature can undoubtedly cause problems like

Researching the CNC-Machine Stiffness Impact on the

2016-1-1 · In this paper authors researched the CNC-machine stiffness impact on the grinding cycle design at few detail types. As a result of calculation by the design method of grinding cycles, 615 allowable grinding cycles were developed. Each cycle was limited by the requirements described in the design method of grinding cycles for circular plunge grinding.

Recent developments in grinding machines

2017-1-1 · Simulation is frequently used in design of grinding machines, as for all machine tools, to enhance static, dynamic and thermal characteristics. Recent advances are demonstrated for static and dynamic behaviour in Refs.,, and for thermal behaviour in Ref. . In contrast to milling or turning applications, the high normal forces in grinding require high system stiffness, which furthermore is
