| Application |
| Staking aluminum captured fasteners on an automated staking press |
Service Conditions |
| 1. | Cold forming aluminum fasteners |
| 2. | Production rates of over 100 forming operations per minute |
| 3. | Light lubrication provided |
| 4. | High
speed staking operation results in high impact loads and high contact
pressures during forming |
| Problems |
| 1. | Existing Tungsten Carbide tooling galls causing rejects and downtime |
| 2. | Mix of steel and aluminum in rejects prevents recycling |
| 3. | Existing
carbide dies must be hand polished with diamond paste to remove galled
aluminum and restore staking surface on die. |
| Solution |
| Replace staking dies with Accuratus yttria stabilized zirconia |
| Results |
 | Galling eliminated |
| | Downtime
significantly reduced; it is now a scheduled maintenance item during
tooling change over |
| | Lubricant usage reduced easing cleaning operations |
| | Easily repolished when necessary using existing polishing techniques |
| Added Note |
| • | This
substitution has also been made on staking dies for plated electrical
connectors with the same dramatic results. |
