Buffing system including load absorbing fixture with multiple compression load deflection and replaceable working face

摘要

A rotary buffing and finishing system includes a polymeric foam cushioning layer that has a graded compression load deflection which is interposed between a backing plate and a relatively thin performance layer that is removably attached to the foam cushioning layer. The backing plate is flexible but has a compression load deflection greater than the cushioning layer, and the cushioning layer includes two foam layers of graded compression load deflection that decreases from a rear face to a front face. The system provides improved performance over thicker and more expensive performance layers while reducing operator fatigue.
