Energy and temperature analysis in grinding

damage. Generally, it is found that the higher is the machining temperature, the greater is the damage caused to the workpiece. Deleterious effects of high temperatures may include tensile residual stresses, increased roughness, oxidation, discoloration, softening or re-hardening of surfaces including brittle

How Temperature Affect Grinding Efficiency

The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1. As can be seen, the effect at high ...

Grinding machine - Wikipedia

The grinding machine consists of a bed with a fixture to guide and hold the work piece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel’s diameter and manufacturer’s rating. The grinding head can travel across a fixed work piece, or the work piece can be moved while the grind head stays in a fixed position. Fine control of the grinding head or table position is possible using a verniercalibrated hand wheel, or us…
