Tool and Die Machining — Close Tolerance Capabilities
JPT’s tool and die machining capabilities are built around close tolerance machining processes — grinding, EDM wire, EDM sinker, CNC turning, CNC milling, and CMM inspection. Our tool and die machining services support both new die builds and replacement component programs.
Close tolerance machining for tool and die applications requires process discipline, material knowledge, and the right equipment. JPT holds the tight tolerances required for precision die components in demanding production environments — routinely machining tool steel components to tolerances measured in tenths of a thousandth of an inch.
Our close tolerance machining capabilities include:
- CNC internal grinding — precision bore grinding for die components
- CNC external grinding — OD grinding for punches, inserts, and wear components
- EDM wire cutting — complex profiles in hardened tool steel
- EDM sinker — blind cavities and complex forms in hardened materials
- CMM inspection — full dimensional verification before shipment

JPT has been manufacturing tool and die components for Michigan manufacturers since 1971. Our facility in Macomb, Michigan is equipped with precision CNC grinding, EDM wire, EDM sinker, CNC milling, CNC turning, and CMM inspection — giving us the complete capability to manufacture complex die components from raw material to finished, fit-up ready parts. We work with tool rooms, die shops, and stamping operations across Michigan and the Midwest, delivering replacement die components, new die builds, and prototype parts with the speed and accuracy demanding production environments require.
Whether you need a single replacement die insert on a rush basis or a complete set of precision die components for a new progressive die build, JPT delivers. Our engineering team reviews your prints, confirms material specifications, identifies any concerns before machining begins, and delivers fully documented, inspection-verified tool and die components ready for immediate installation. That is the JPT standard — and it is why Michigan tool and die shops, stamping operations, and precision manufacturers have trusted JPT for tool and die components for over 50 years.

The JPT Way
Most tooling problems aren’t solved by buying off the shelf. They’re solved by understanding the application, the machine, and the process — then engineering the right solution.
Cutting tools. Fixturing. Complete production solutions. That’s been the JPT way since 1971. No catalogs. No guessing. Just engineering.
