41633466, Aug 7, 1979

Filed:

Feb 1, 1978

Appl. No.:

5/874312

Inventors:

Charles B. Matson - Cincinnati OH

Assignee:

Cincinnati Milacron Inc. - Cincinnati OH

International Classification:

B24B 4916
B24B 5314

US Classification:

5116577

Abstract:

A tangential grinding machine has a variable grinding feed rate which is dependent upon the length of the cutting or grinding path which occurs between the grinding wheel and a workpiece. The variable feed rate accomodates fluctuations in grinding wheel and workpiece dimensions to control the grinding time and optimize stock removal rates.

Abstract:

A grinder has an abrasive belt removably mounted on a wheel for grinding a workpiece. The belt has its ends extend through a transverse slot in the wheel into a recess within the wheel. One end of the belt is attached to a first slider and the other end of the belt is attached to a second slider with the sliders increasing the tension on the ends of the belt through outward movement of the sliders by centrifugal force as the wheel rotates with the tension increasing as the angular velocity of the wheel increases. The sliders may move parallel to each other or along two separate radii extending from the axis of rotation of the wheel. Pivotally mounted pendulums may be employed instead of the sliders to apply tension to each end of the belt with the pendulums increasing the tension on the ends of the belt through outward movement of the pendulums by centrifugal force created by rotation of the wheel.
