how we deliver

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.

Pinnacle offers high-quality, high-volume CNC machining, routing, turning, and milling capabilities to meet demanding customer specifications. 

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.

a question we get:

What are the benefits of multi-axis machines in sheet metal machining?

Multi-axis machining centers, like the ones on the Pinnacle Precision production floor, are essential in fabricating precision sheet metal parts because they offer our Production team greater accuracy, flexibility, and efficiency.

There are many benefits to customers when they work with a manufacturing partner who uses multi-axis machines, including:

Higher Productivity: Multi-axis machines give manufacturers the ability to access multiple sides of a part without repositioning, reducing idle time and maximizing machine efficiency

Improved Quality: The precision of these machines produces parts with tighter tolerances and better surface finishes.

Increased Efficiency: More accurately machined parts equals less reliance on secondary operations like grinding, sanding, and polishing.

Reduced Set-Up Time: CNC programming enables a one-time set-up of a multi-axis machine, reducing re-set downtime found in traditional machining methods.

Competitive Advantage: The precision, accuracy, and reliability of parts and components produced via multi-axis machines offer manufacturers better parts, components, and assemblies.

Multi-axis machines accurately and efficiently perform cutting, punching, machining, forming, drilling, milling, tapping, and threading operations.

Pinnacle utilizes several multi-axis machines to produce sheet metal parts and components with complex designs for our customers in the aerospace, defense, medical, and renewable energy industries.
