Manufacturing aids designed to make a process repeatable.

How Spartan approaches tooling

We design tooling around the real manufacturing process: locating strategy, clamping, access, inspection, operator use, repeatability, maintenance, and changeover. A fixture is successful when it consistently creates acceptable parts without unnecessary complexity.

Our standards

There is no single universal tolerance for every fixture. The standard follows the function. Machined tooling features use our standard CNC machining defaults unless the drawing or tooling requirement calls for tighter control.

• Critical locators and datum relationships are identified before manufacture.
• Mating and repeatability features are inspected to the agreed drawing or functional requirement.
• Sharp edges are deburred unless they are intentionally functional.
• Replaceable wear items, service access, and operator handling are considered when appropriate.
• When tooling must prove a part or process, acceptance criteria are agreed before final signoff.

Where the tooling includes fabricated structures, formed parts, or welded elements, the applicable fabrication standards are used for those portions of the assembly.
