ABSTRACT:
A grinding method for a vertical type of double disk surface grinding machine comprising a pair of rotating grinding wheels vertically opposed to each other and vertically movable and a moving table for moving a work having a work holding jig, wherein vertical positions of the upper and the lower surfaces of the work to be ground prior to the grinding operation are measured by means of a pre-grinding dimension measuring instrument disposed in a vicinity of the work attaching/detaching position and the standby positions of the grinding wheels are set based on the measured values in a step, the work is moved to the grinding position and the grinding wheels are moved at a high feeding speed from the set standby positions to grinding start positions in contact with the work or positions immediately before making the contact in a subsequent step, and the work is ground at a grinding speed lower than the feeding speed in a further subsequent step.
