An ice shaving apparatus which causes an ice block to be rotated against a cutting blade, the apparatus having a motor which rotates a shaft joined to a drive plate which retains the ice block, the shaft being joined to a piston head within a cylinder, where an air pump provides pneumatic pressure to move the piston head vertically in the axial direction within the cylinder to move the ice block in the axial direction against the cutting blade as the lower surface of the ice block is removed by rotational movement. The air pump is regulated such that a constant pressure is maintained against the piston head.
