Mich. Admin. Code R. 408.10155 - Mounting of abrasive disc wheels
Rule 155.
(1)
An inserted nut wheel shall be mounted with a steel machine face plate of the
same diameter as the wheel. The thickness of the machine face plate shall be as
prescribed in table 19 of
R
408.10199.
(2) A screw hole in the machine face plate
shall be located to match the threaded hole in the inserted nut and large
enough so the screw will not bind. Each screw hole in the plate shall be
countersunk to a uniform depth to accommodate the screw head. A screw shall
engage the threads of the inserted nuts, but not touch the bottom of the
hole.
(3) A machine face plate
shall be flat, concentric and mounted at a 90 degree angle to the machine
spindle.
(4) A plate mounted wheel
having a mounting plate thinner than prescribed in table 19 shall have an
additional machine face plate installed to provide the additional strength
needed. The added machine face plate shall have the same diameter as the wheel
(see figure 22 of
R
408.10198 and table 20 of
R
408.10199).
