Deflashing machine and method of deflashing a lens-mold-assembly

A method of deflashing a lens-mold-assembly after molding, the method comprising:

• rotating the lens-mold-assembly held between coaxially aligned first and second rotary parts of a lens-mold-assembly-rotation mechanism of a deflashing machine, wherein the first and second rotary parts are axially spaced from each other along a common axis for holding the lens-mold-assembly therebetween, and wherein the first and second rotary parts are rotatable about the common axis to rotate the lens-mold-assembly;
• engaging a circumferential surface of the lens-mold-assembly with a trimming edge of a first blade of a deflashing mechanism of the deflashing machine, wherein the first blade is disposed at a first radial position from the common axis and the trimming edge of the first blade is parallel to the common axis;
• and
• engaging a convex surface or a concave surface of the lens-mold-assembly with a trimming edge of a second blade of the deflashing mechanism of the deflashing machine, wherein the second blade is disposed at a second radial position from the common axis and the trimming edge of the second blade is radially aligned with respect to the common axis.
