| 20090148249 | PCBN Cutting Tool Components - A cutting tool component ( | 06-11-2009 |
Peter Michael Harden, County IE
| Patent application number | Description | Published |
|---|---|---|
| 20090126541 | Cutting Method - A cutting tool component which has an ultra-thin layer of ultra-hard material bonded to a cemented carbide substrate. The ultra-thin layer of ultra-hard material has a thickness of no greater than 0.2 mm. This cutting tool is used to cut workpieces under roughing and/or interrupted cut conditions. Where the workpiece is a wood product or wood composite the invention extends to cutting such workpieces in general. The ultra-hard material is preferably PCD or PCBN. | 05-21-2009 |
