The invention relates to the technical field of wine cabinet machining. A grinding machine for a wine storage cell of a wine cabinet comprises a base, a supporting sleeve, a grinding head and a motor, wherein the grinding head is connected with the shaft of the motor; the base is connected with an inclined automatic power cut switch; a plurality of rubber pads are arranged on the lower surface of the base; a motor shell is provided with a pull handle; the pull handle is provided with a sleeve; an elasticity adjustment mechanism is arranged between the pull handle and the sleeve, and comprises a base pipe, a clamping layer and a pre-tightening force adjustment mechanism; the clamping layer consists of a plurality of friction strips; the friction strips are provided with a plurality of sliding rods arranged on the base pipe in a penetrating manner; and third springs which drive the sliding rods to move outwards are arranged at the inner ends of the sliding rods. The invention provides the grinding machine which can automatically stop grinding when inclined and quickly grind the wine storage cell in a labor-saving manner and maintain the surface co-roundness of the ground wine storage cell, so that the problems of high labor intensity and low co-roundness which are caused by the fact that the peripheral surface of the wine storage cell is ground by artificially holding and rotating the wine storage cell are solved.
