Abstract

The invention discloses a lapping head with floating grinders consisting of a body (20) within which is attached a ring-gear (7) with inner cogs engaging a pinion gear (6) coupled with a central eccentric collar (10), which in turn is co-axially coupled with a vertical shaft (2) attached to the body (20). The central eccentric collar (10) co-operates through a cylinder-shaped collar (11) and through mechanical connecting means (8,9,16,17) both with planetary eccentric collars (13) attached to the body (20), and with each shaft (18) attached to the support (19) holding each grinder (40), wherein the floating motion of each grinder occurs when the vertical shaft (2) rotates, thereby bringing the body (20) of the lapping head to which it is attached into rotation. <IMAGE>
