About American Modular Tooling
AMT© is the world's finest and most comprehensive modular fixturing system for CMM workholding. Made of high tensile strength aircraft aluminum, every element has been carefully designed for maximum efficiency and cross-system adaptability.
Agile parts fixturing, rapid tool development, flexible machining and fast assembly make the American Modular Tooling system an ideal addition to the worldwide movement for lean, efficient methods of manufacturing. Components are available individually, in kits or as custom fixtures designed and built per your part print.

AMT Advantages:
- Fixtures may be built rapidly and modified easily, resulting in an immediate savings of time and money.
- All components are completely reusable, unlike welded fixtures.
- Aluminum is light in weight, resists corrosion and will not rust.
- Modular elements make it easy to duplicate, or repeat, designs.
- Large fixtures, such as body cubes may be built in sections which can be assembled or dismantled quickly, permitting work at multiple locations.
- Parts on a body cube may readily appear in body position.
- A fixture may be assembled away from its site without blocking a CMM.
