Since wheel slide unit may be placed to suit customer and be
cause various placements (jive unusual conditions in clearances,
it is suggested if adaptability of Angular Wheel Slide Arrange

10" Type
Incorporating several noteworthy features, the Angular Wheel
Slide Arrangement available in the 10" Type C line is entirely
different from any other Norton machine giving an angular
setting of the wheel in relation to the table.
Angularity of wheel slide, selected by customer, may be varied
between 15° and 45°. Angle is set at factory. Subsequent
change, not available as an adjustment, may be engineered by
Norton Company.
While any wheel slide angle within defined limits is possible,
angles of 15°, 30° or 45° generally cover most requirements.
In the Angular Wrheel Slide Arrangement the slide moves toward
work at predetermined angle to table,
vious constructions in which movement of slide is at right

by jogging table. With Angular Wheel Slide Arrangement, two
adjacent surfaces are ground simultaneously. Increased produc
tion and reduced wheel wear result. Using multi-wheel mounting,
additional face can be ground.

Distance from floor to work center is but 35", a convenient
height popular with operators.
