Abstract:
This invention relates to certain improvements in grinding or polishing machines, and relates more particularly to flat-surface grinders or what are generally known in the trade 1as "disk" grinders. An object of the invention is to provide certain improvements in bearings or mountings for the arbor of a flat or circular surface grinding-machine wherein the arbor carries one or more vertically or otherwise disposed grinding-surfaces, usually circular disks or chucks rigidly secured to both outer ends of the arbor and carrying the abrading or grinding surfaces, the work being- applied to the abrading-surfaces at the outer faces of said disks or chucks, a table or -other fixture or support being provided for each abrading disk or surface to hold the work.
Claim:
In combination, in a surface grinding-machine, a support, a rotary arbor mounted therein and having an end outwardly tapered with a reduced shouldered threaded extremity, a collar slipped on said tapered end, a key to hold the parts to rotate together and permitting removal of the collar, said collar having a reduced outwardly-extending hub around said extremity and having an end nut- 1 recess, a clamping-nut screwed on said threaded extremity and located in said recess, a grinding-head fitted on said hub and against the outer face of the collar, and means for removably clamping the head to the collar. |
