APPi Machining concentrates on complex, close tolerance and finely finished components parts, manufactured to your specifications and requirements. At APPi we know how to make all the pieces come together. Whether your needs are for parts to print or manufacturing recommendations we have the equipment and experience to provide a sound business solution.

We have the ability to translate your CAD data into CNC Turning, Milling and Swiss Machined components from the simple to highly complex. We work with all materials. Our parts range in size from microscopic to a 15" cube, with tolerances to .000010.





CNC MACHINING CENTERS- Horizontal and Vertical Milling and drilling up to 4 axis. Complex components, Plastic to Exotic materials. We are your single source for a complete product.

CNC TURNING CENTERS- Swiss style turning to 20mm in 5 axis. Mill/Turn Centers with a bar capacity of 2-3/4" diameter with the ability to manufacture complex parts in 7 axis.

SECONDARY OPERATIONS- Precision Grinding and Lapping on metals and ceramics to close tolerances and fine finishes down to 2 micro inches. We can achieve special finishes by polishing, bead blasting, Electro Plating, and painting. We assembly components into sub assemblies and assemblies for OEM manufacturers.

Precision machined components represent a major design commitment. We match that commitment with equipment and processes capable of machining virtually any material into finished parts. Listed below is a matrix of machining processes and the tolerance we can achieve in production on a sample of different materials.
