The Pinnacle CNC machining process


Each project coming into our Southern California headquarters receives maximum attention and care from the Pinnacle Precision team. It starts with our Customer Support team, which excels in translating customer needs into actionable plans for our Technical, Production, and Quality Assurance teams.

Finishes & Treatments: We provide a range of finishes, including vibratory and barrel-type deburring, line graining, cyclone bead blasting, and more, to enhance the product’s appearance and performance.

Prototype to Production: Our team is adept at turning prototypes into high-quality, mass-produced components and assemblies, optimizing for efficiency and precision at every stage.

Manufacturing: Pinnacle’s Production team leverages the power of CNC laser cutters and punch presses to fabricate precision sheets sent to our machining, forming, bending, and welding crews. From there, our Finishing and Assembly teams handle electromechanical assembly, hardware installation, and seal applications before our Quality team inspects the final product. 

The difference between Pinnacle and any other company is our team-forward integrated approach and solutions-first mentality. We look forward to proving our promise to you.
