thermal damage in grinding

Surface Hardening: Hard Turning or Grinding? | Gear ...

Both turned and ground surfaces are free of thermal damage. It is interesting to note that a thermal damage free surface has two clearly visible zones characterized by: the strain hardened zone in near surface and the thermal affected zone in subsurface (not softened compared with bulk hardness as seen in the following section).

One of the major goals in grinding processes is to get rid of the heat generated in the contact zone between abrasive and workpiece. An inadequate or not efficient heat removal can lead to thermal damage at the ground

Wheel lift-off in creep-feed grinding: thermal damage ...

An investigation is made into the phenomenon of early lift-off in creep-feed grinding, where the wheel lifts away from the workpiece before reaching the end of cut. In single-pass operations, early lift-off can result in thermal damage. In multi-pass operations, there is a surge in material-removal rate just before lift-off, which can result in thermal damage and excess wheel wear.

AVOIDING THERMAL DAMAGE IN GRINDING

In some grinding applications, the use of an oil is impractical and a water-based fluid must be chosen. when this is the case, other measures can be taken to reduce the likelihood of thermal damage. The temperature of the grinding fluid, for example, has a pronounced influence on its heat …

7 Fundamentals of the Centerless Grinding Process

In the centerless grinding process, the angles at which the wheels contact the part are critical to achieving the proper roundness and tolerance. Generally, the centers of the regulating and grinding wheels are set at the same height on the machine, and the center of the workpiece is situated higher.
