Shine Abrasives Effect Of Metal Powder Vitrified Bond Wheels Diamond Tool
Shine Abrasives Effect of metal powder quality control on diamond tool performance
Vitrified Diamond grinding wheel is most commonly employed in the grinding of PCD and PCBN tools, and it also have enabled polycrystalline tool fabricators to obtain excellent surface finishes, quickly and productively. Vitrified grinding wheels can also be used in the fabrication of sapphire, as well as many dense ceramic materials and so on.
| Grit Size | Machining Type | Application |
| D22 | Rough | Regeneration grinding a blade edge, profiling and sharpening of worn inserts. |
| D15 | Universal | Standard grain size - there is a possibility of obtaining a high sharpening efficiency and good quality machined surfaces by taking advantage of additional spark-out passes. |
| D9 | Finish | Finishing grinding - obtaining a very good quality of machined surfaces. |
| D6 | Superfinish | Superfinish grinding - obtaining a brilliant quality of machined surfaces. |
Any nonstandard size and grits size can customised.
The hardness of the sintered matrix is mainly related to the properties of the metal powder particles, structural uniformity, interface bonding strength and densification degree (porosity). The oxygen content of metal powder has no significant effect on the hardness of sintered samples. If the oxides inside the powder are distributed in a dispersed state, it will increase the lattice distortion energy inside the powder particles and increase the hardness of the particles.
