METAL PREPARATION POLISHING PADS

Many companies have the need to prepare samples of the materials or metal products they manufacture. Analysis of a material's metallographic microstructure will show if the material has been processed correctly. It is a critical step for determining product reliability. After samples have been cut, ground or lapped they will need to be polished. Spartan Polishing Pads can be employed to remove the necessary bulk material while maintaining excellent flatness. A softer polishing pad can be used to improve the surface quality prior to examination.

Another example of metals polishing is when a primary component needs to be taken from an “as-lapped” surface to a polished surface. Aluminum disk polishing, valve seals, spacers and other specialty parts require precision surfaces. Careful selection of Spartan Polishing Pads in conjunction with the proper abrasive and suspension agent will provide a highly polished surface.

POLISHING PAD DETAILED INFORMATION

All pads are available plain and perforated. Embossing is available, but limited. Please inquire about specific applications.

All pads are available with our own specially developed PSA, magnetic or loop backing to be used with various hook attachments. We currently have 2 types of PSA that cover 2 specific markets. Our standard is for the glass industry is one that resists temps up to 120F, peels easily from the plate and can actually be reapplied. Our second type of PSA is a 3M product that is temperature resistant up to 160F, resistant of Ph changes from 5 to 10, but may leave some adhesive on the plate (depending on how it is run and removed).
