Abstract
The present disclosure includes one or more resilient members for use in an apparatus used to form lapping plates. The resilient members can permit processing members such as charging elements and shaving blades to conform to irregularities in surface topography of lapping plate platens.
Claims18
1) A method of processing a major surface of a lapping plate platen during the manufacture of an abrasive surface on the major surface of the lapping plate platen, wherein the method comprises contacting a major surface of the lapping plate platen with at least one processing member under pressure to modify the surface of the lapping plate platen during the manufacture of the abrasive surface on the major surface of the lapping plate platen, wherein the at least one processing member is part of a processing head comprising:
- i) a base;
- ii) at least one resilient member attached to the base;
- and
- iii) the at least one processing member attached to the at least one resilient member, wherein the at least one resilient member permits the at least one processing member to elastically move in response to a pressure increase while the at least one processing member is in contact the major surface of the lapping plate platen under pressure to modify the surface of the lapping plate platen during the manufacture of the abrasive surface on the major surface of the lapping plate platen, wherein the processing head mechanism is configured to move the processing head to contact the major surface of the lapping plate platen with the at least one processing member under pressure to modify the surface of the lapping plate platen during the manufacture of the abrasive surface on the major surface of the lapping plate platen, wherein the processing head rotates about a first axis and the lapping plate platen rotates about a second axis, and wherein the first axis is parallel to and offset from the second axis.
