Now for the 5 most common problems and how to fix them: 1. The workpiece is burnt. In the feed too fast - Reduce the amount of stock removed per pass. Dressing on the wheel is too fine - Use a coarser dressing, more 'open'. Poor coolant direction - Adjust the coolant direction into the grinding area. 2.

Machines in which grinding wheels are fitted and grinding is done, such machines are called grinding machines. On the basis of their function, they can be divided into two parts. Ordinary grinding machines are widely used. These are called rough or snagging grinders. The following types of grinders are included in this category.

Eddy current is an effective method to detect grinding burns and does not suffer the environmental or fire hazards of nital etching. Like nital etching, eddy current testing will only detect a grinding burn if a metallurgical transformation has occurred. It can detect surface softening but is not able to detect residual stresses.
