II. Scraping
- Hartford’s well trained hand scraping team produces high precision machine tools by exquisite hand scraping skills. We carefully inspect our machines to reach the best quality and ensure that every contact surface is precisely hand scraped.
- Scrapping points comply with optimal usage standard with 10 to 12 points in one square inches
- Platform is maintained monthly by technicians and examined annually by the 3D coordinate measuring machine.
- Hand scraping of key component fixed surfaces
- Key components such as headstock, taper gib, table, bearing housing and motor base are all scraped by our professional technician.
