Historically, there are two methods of polishing and grinding process for composite materials:
Traditional Method:
Grinding process – 320, 600, 800, and 1200 grits
Polishing process – 6 um (polishing cloth), 3um (polishing cloth), 1um (polishing cloth) along with aluminum oxide powder or diamond suspension fluid
Contemporary Method:
Grinding process – 240 SIC paper
Polishing process – 9um (diamond platen – Golden), 6um (polishing cloth), 1um (polishing cloth) with diamond suspension fluid
Standard Engineering Recommendations:
The below process offers a standard recommendation for polishing and grinding needs. This can be adjusted as needed, depending on your materials and surface finish requirements. Contact our qualified consultants to learn more.
Here is a cost effective
GRINDING:
The most cost-effective consumables option for grinding would include a combination of our 12-inch MAGNEPAD Stainless Steel Magnetic Base Plate – Part #: SSMAG-P12 combined with the following adhesive backed grinding pads. Our recommendation based on your material and relatively smooth starting surface would be to start with:
240 Grit paper – Part #: SIC-240P12-100
600 Grit paper – Part #: SIC-600P12-100
1200 Grit paper – Part #: SIC-1200P12-100
You can always add more grinding paper grits as needed.
NOTE: For optimal convenience, you would require one Steel Magnetic Base Plate per grinding paper.
This combination will allow you to easily switch out your stainless steel magnetic base plates with grinding paper as needed; while benefiting from using the adhesive backed grinding paper, which is much more cost effective than magnetic grinding paper.
POLISHING:
After your grinding procedure, we would recommend using our 12-inch ATLANTIS Polishing Pad with Magnetic Rubber (Part #: ATL-3012-MAG) along with 1 micron DIAMAT Polycrystalline High Viscosity Diamond Abrasive (Part #: PC-1001-500).
The pads can go directly onto the magnetic base plates of the main unit. They are extremely easy to switch out and have a high life-span.
NOTE:
Should better polishing be required, we would suggest moving into the alumina diamond suspensions.
