Precision Spindle Unit SIGMA Series Product Features

2021-2-5  While the spindle is spinning, the extremely low air pressure field occurs due to centrifugal force and it prevents contamination by the foreign substance by creating the air pressure difference. Besides, applying coolant or air blow onto the spindle unit, when the spindle

Factors affecting proper coolant application when

2017-8-11  Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.

In Grinding, Coolant Application Matters

2008-3-1  Even when a nozzle pressure of 58 psi (406 kPa) is required to match a wheel speed of 6000 fpm (18,288 m/min), a pressure of over 200 psi (1400 kPa) may be used. Often the engineer is grinding stringy and ductile materials, such as medical stainless, Inconel, and titanium, and they are seeing the benefit of wheel cleaning as much as cooling.
