The wheel spindle
The wheel spindle is carried in bearing in the wheel-head, the bearings being specially designed to reduce the working clearance to the minimum.
The wheel-head is supported on a compound slide. The top portion carrying the wheel spindle can be swiveled on an intermediate member, which can slide along a lower member. The latter in turn can be swiveled on the bed of the machine. The cross feed of the wheel – head canthus be arranged at any angle to the work-table ways: also the wheel spindle axis can be at angle to the wheel- head slide. The feed to the wheel-head may be given, either by hand or by means of a mechanically operated ratchet mechanism, at one end only of the traverse of the work or at both ends.
The reversing mechanism of the worktable traverse motion can be arranged to provide a “dwell” at one or both ends of the motion. An internal grinding spindle is permanently mounted on th
