ABSTRACT:
The work supporting unit or units on the stationary or reciprocable work supporting table of a plain grinding machine are adjustable with reference to the table by one of the existing numerically controlled drives, such as the drive which reciprocates the table with reference to a stationary base or the drive which reciprocates a carriage for the grinding wheel relative to a stationary table. The locking device or devices which normally fix the adjustable unit or units to the table are disengaged and the unit or units are separably coupled to the reciprocable part (table or carriage) by suitable detents which can be engaged or disengaged by numerically controlled drives or by an existing drive such as the drive for a slide which is reciprocably mounted on the reciprocable carriage and supports the grinding wheel.
