Abstract
An abrasive cutting blade is provided to achieve high-quality surface finishes at high feed rates. The blade is fabricated by electroplating fine abrasive onto a steel cathode disc to form a first layer, followed by electroplating a second layer of coarser abrasive onto the first layer. A third layer of fine abrasive is then electroplated onto the second layer. The resulting composite is then removed from the cathode disc to form a multi-grit, multi-layer, hub-less blade.
Claims9
An abrasive slicing disc comprising:
- a first layer of electroplating having first-size abrasive particulate dispersed therein;
- the first-size being within a range of:
- at least about four microns;
- and
- up to about eight microns;
- a second layer of electroplating having a second-size abrasive particulate dispersed therein;
- the second-size being within a range of:
- at least about ten microns;
- and
- up to about twenty microns;
- a third layer of electroplating having the first-size abrasive particulate dispersed therein;
- the first, second, and third layers being superposed with one another;
- and
- the second layer being disposed between the first and third layers;
- wherein abrasive particulate is dispersed throughout the disc.
