- Embodiment 28 The abrasive article of any of the preceding embodiments further comprising a plurality of abrasive bodies attached to a major planar surface of a substrate, wherein the plurality of abrasive bodies includes a plurality of first abrasive bodies and a plurality of second abrasive bodies, wherein the first and second abrasive bodies are arranged in a radial alternating manner relative to each other.
- Embodiment 29 The abrasive article of embodiment 1, wherein the abrasive article is a cup wheel.
- Embodiment 30 A method of using the abrasive article of embodiment 1, comprising edge grinding.
- Embodiment 31 A method of using the abrasive article of embodiment 1, comprising grinding a material that comprises AlTiC.
- Vitreous bond abrasive segments were prepared according to the following procedure.
- a mixture of abrasive diamond particles and glass frit was prepared according to the composition detailed below in table 1.
- the mixture was mixed in a Resodyn LabRam acoustic mixer for Imin at 100% intensity.
- a round divot was then created in the center of the mixture, and a PEG binder was added.
- the mixture was again mixed in a Resodyn LabRam acoustic mixer for 1 min at 100% intensity.
- the mixed powder is then screened through a 20s s screen and left out to dry overnight. The following day the mixture is screened again.
- the mix was molded in a steel mold with a diameter of 5.02” and a target molded thickness of 0.325”.
- the mold was pressed with 25 tons of force for 15 seconds to form an abrasive body precursor.
- the abrasive body precursor was placed on a 6” square batt and then placed in a furnace for firing.
- the timing and temperature of the filing process are detailed below in Table 2.
- Vitreous bond abrasive segments were prepared according to the following procedure.
- a mixture of abrasive diamond particles and phenolic resin particles was prepared according to the composition detailed below in Table 3. The mixture was mixed in a Resodyn LabRam acoustic mixer. Glass spheres were added according to Table 1, and then the mixture was mixed again.
- the mixture was then pressed in a hot press at 180 °C for 20 minutes in order to form an abrasive body.
- vitreous and resin abrasive bodies were then cut into abrasive segments and cemented to a substrate in an alternating fashion.
- the cement is then cured 4 hours at 60°C, forming an abrasive cup wheel.
- references herein to a material including one or more components may be interpreted to include at least one embodiment wherein the material consists essentially of the one or more components identified.
- the term “consisting essentially” will be interpreted to include a composition including those materials identified and excluding all other materials except in minority contents (e.g., impurity contents), which do not significantly alter the properties of the material.
- any of the compositions identified herein may be essentially free of materials that are not expressly disclosed.
- the embodiments herein include a range of contents for certain components within a material, and it will be appreciated that the contents of the components within a given material total 100%.
