(2) Fixtures for internal grinding. For grinding internal surfaces of simple circular workpieces, the chuck may be used as a standard workholding device. If required, special jaws can be provided for the chuck. However, for many components, special fixtures may have to be made which are designed on the same lines, as the lathe fixtures.
(3) Fixture for surface grinding. The workpiece can be held for machining on a surface grinder in the following ways :
(i) It may be clamped directly to the machine table or to an angle plate and so on.
(ii) It may be held in a vise.
(iii) The workpiece may be held by means of a magnetic chuck or a vacuum chuck. Here, the workpiece is held without any mechanical clamping.
(iv) The workpiece may be held in a special fixture.
