Fine Grinding

Westmoreland Plastics has the ability to finish any molded product that requires special flatness, parallelism, surface finish, and size specifications.

 Traditional lapping is one type of technology that we offer:

• Loose abrasive is added to the table for stock removal using a rolling action.
• A lapped surface is dull and crater-like.
• Lapping compound cannot be recycled.
• Lapped parts are somewhat dirty and require cleaning.
• Although very accurate, stock removal rates are slow.

Fine-Grinding, a more advanced technology, offers several advantages over the traditional lapping process, while maintaining similar levels of precision:

• Stock removal is performed by fixed super abrasive plates using a scraping action.
• A fine-ground surface has irregular crossing marks.
• The coolant used on the table can be recycled and creates a more positive impact on the work environment.
• This process can average between 3-20 times faster than lapping.

Fine-grinding at Westmoreland consistently provides precise and repeatable results at significantly lower costs.

Part applications:

• Seal rings
• Metering devices
