PROBLEM TO BE SOLVED: To apply fine lens processing pressure and perform the fine adjustment, in a lens processing device cutting and polishing a surface of a lens material to be a processing object, while performing dependent rotation of the surface of the lens material by pressing the surface on a processing surface of a rotating lens processing tool. SOLUTION: A lens pressurizing mechanism is incorporated between a lower end part of a lens supporting shaft 3 of the lens processing device 1 and a lens holding tool 5. The lens pressurizing mechanism is provided with a pressurizing spring 14 and a pressure nut 13 for adjusting the compression amount. Since weight of the lens supporting shaft 3 does not act as processing pressure on the lens holding tool 5, a fine adjustment of processing pressure can be accurately performed. Inertia force of the lens supporting shaft 3 does not act on the lens holding tool 5, and thereby the lens holding tool 5 vertically moves by following vibration, etc. when performing processing and excessive force is not added to a lens material 6 or the like.
