The abrasives may be used also in powder form by charging the grinding surfaces with the abrasive in a premixed slurry or suspension. SiC particles, particularly with the finer size papers, embed easily when grinding soft metals, such as Pb, Sn, Cd and Bi (see Figure 3.1). Embedding of diamond abrasive is also a problem with these soft metals ...

May 13, 2016· Yeah, im doubting youd be work on a "green" PM part doing grinding. It would just crumble. It has to be sintered to have any mechanical properties. Heat treating is a different ball of wax. If its normalized, it should be just fine. Go to town. But you still need to know what the material is that youre grinding.

Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder …

The CA glue will flow through the narrow spaces between the bits of metal in a process called capillary action. If you ground the powder too fine, the CA glue will not be able to penetrate the powder, and it will sit on top of the powder. If this happens, you may need to grind a new batch of powder. Do not oversaturate the powder.

Powder metallurgy processes use sintering to convert metal powders and other unique materials into end-use parts. Sintering typically takes place in a single, elongated furnace with different temperature zones. To facilitate the process, alloying elements or pressing lubricants may be added to the metal powder.
