a die cylinder comprising a plurality of mounting points for installing respective cutting components; a sleeve comprising a magnetic component configured to removably magnetically attach to the die cylinder, wherein the sleeve covers at least one of the plurality of mounting points; an anvil cover disposed on the anvil cylinder; and a motor to cause rotation of the anvil cylinder, wherein the rotation of the anvil cylinder causes the sleeve to generate a pressing force on the anvil cover to force a locking component of the anvil cover into the horizontal lock channel of the anvil cylinder to secure the anvil cover on the anvil cylinder, wherein when the sleeve is removed from the die cylinder, one or more cutting components are installed at one or more of the plurality of mounting points, and wherein the anvil cylinder with the anvil cover securely installed thereon provides a platform for a cutting operation. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the locking component comprises a female lock end of the anvil cover, and wherein the pressing force forces the female lock end of the anvil cover into the horizontal lock channel to couple with a male lock end of the anvil cover. ### Claim 3 (depends on 1) The assembly of claim 1, wherein the sleeve comprises a plurality of segments forming a ring cylinder wrapping around the die cylinder. ### Claim 4 (depends on 3) The assembly of claim 3, wherein a diameter of an inner surface of the ring cylinder is greater than or equal to a diameter of the die cylinder. ### Claim 5 (depends on 1) The assembly of claim 1, wherein a first distance between the die cylinder and the anvil cylinder is reduced by a thickness of the sleeve, and wherein the first distance is reduced by the thickness of sleeve to less than a thickness of the anvil cover. ### Claim 6 (depends on 1) The assembly of claim 1, wherein the sleeve comprises one of wood, plastic, or rubber. ### Claim 7 (depends on 1) The assembly of claim 1, wherein the sleeve comprises at least one mounting hole through which the first segment of the sleeve is attached to the die cylinder.
