ABSTRACT:
Provided is a grinding machine comprising a carrier adapted to raise or lower, the carrier including a V-shaped groove across its top and a forward pad at either side, a spindle unit including an inverted L-shaped mounting plate, and a fine tilting adjustment mechanism comprising first, second, third, and fourth screw type fastening units for fastening horizontal and vertical portion of the mounting plate at the carrier. Each screw of the fastening units is spaced from the carrier by a peripheral gap. The gaps are adapted to allow the horizontal or vertical portion of the mounting plate and thus the spindle unit to either tilt to the left or right or tilt to the front or rear with respect to the carrier in response to unfastening the screws and loosening adjustment screws of the fastening units.
