BASIC TURNING AND GRINDING
USING CUTTING FLUIDS
For grinding a job the right grinding wheel is to be selected. The selection of a grinding wheel will depend on the following factors.
The work holding devices used in grinding are:
Magnetic chucks are of two types
The magnetic power of the electro magnetic chuck can be varied according to the size of the work. But not so in the case of a permanent magnetic chuck.
The tempering process consists of heating the hardened steel to the appropriate tempering temperature and soaking at this tempering, for a definite period.
Annealing consists of heating of hypo eutectoid steels to 30t50’c above the upper critical temperature and 50’c above the lover critical temperature for hypereutectoid steels.
Definition:-The process of removing the internal defecate or to refine the structure of steel components is cold normalizing.
