Tight Tolerance CNC Machining

High precision CNC machining (Computer Numerical Control) is a manufacturing process in which numerous types of pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control several different types of multifaceted machinery. With custom CNC precision machining services, three-dimensional cutting tasks can be accomplished in a single set of prompts.

Using state-of-the-art technology and years of experience, Petersen Precision provides full-service CNC machining for complex, three-dimensional metal parts and components. With more than 35 CNC machining centers and “lights out” production capabilities, we can deliver the machined parts you need quickly and efficiently, with exceptional precision and great repeatability from the first piece to the last.

Contact us for more information regarding our CNC machined parts finishing capabilities and CNC production machining services, or call us at 650-365-4373 and we will be happy to assist you. We are the proven experts in tight tolerance precision machining services.

What is High Precision CNC Machining?

CNC production machining services produces parts with tight tolerances and excellent material properties. CNC is suitable for both one-off jobs and low-to-medium volume production (up to 1000 10,000 parts a week), due to its high repeatability. Within the CNC machine manufacturing process material is removed from a solid block using a variety of cutting tools to produce a part based on a CAD model. As an added benefit, both metals and plastics can be machined with CNC.

Benefits of CNC Machined Parts Finishing

There are numerous advantages of utilizing custom CNC precision machining services for tool and part creation. The main benefits associated with close tolerance CNC machine manufacturing, include:

  • Provides excellent accuracy and repeatability, while producing parts with very tight tolerances, making it ideal for high-end applications.
  • CNC machined parts finishing materials provide excellent and fully-isotropic physical properties and are suitable for most engineering applications.
  • Established as an extremely cost-effective manufacturing process for producing the low-to-medium numbers of metal parts (from one-off prototypes, up to 1000 units or more)

CNC Machine Manufacturing for High Precision, High Volume Part Production

With multi-axis vertical and horizontal CNC machining technology, Petersen Precision can produce even the most intricate parts with feature-to-feature and profile tolerances of ±0.0005” and positional tolerances of ±0.001” or better. High-speed spindle capabilities (up to 30,000 RPM) allow for fine feature work on parts for medical, aerospace, and other demanding industries. We work with your CAD or other digital design files to deliver precision machined parts that match your exact specifications.

We specialize in high volume CNC tight tolerance precision machining manufacturing (tens of thousands to hundreds of thousands of parts or more), which enables us to run our CNC systems with a single tooling setup for extended periods for faster and more efficient manufacturing. Most parts are run on pallets or tombstones, which enables us to unload finished parts and load in raw materials while other parts are being machined for non-stop production. Our CNC department is equipped for 24/6 non-stop manufacturing, including overnight, lights out work processes.

CNC Machined Parts Finishing Processes

In addition to producing parts from scratch, we also use CNC machining to finish parts we produce via fineblanking and other processes. With CNC machining, we can tap holes, add chamfers, and provide other complex features that our customers’ part designs require.

Materials for Close Tolerance CNC Machine Manufacturing

We work with a broad range of standard and exotic materials in our CNC machining processes. We can produce your machined parts from:

High Precision CNC Machining Integrated Quality Control Processes

At Petersen Precision, our custom CNC precision machining services department is fully integrated with our quality assurance department. We use Zeiss CMM (coordinate measuring machine) systems for in-process and final production checks to ensure the accuracy and quality of finished parts.

Design for Manufacturing (DFM)

We offer DFM services to your R&D and Development teams to optimize your part designs for faster, easier, and more cost-effective manufacturing. Our engineers will work with you to improve the manufacturability of your parts without sacrificing fit, form, or function.

In-House Tooling Shop

Tooling for our high precision CNC machining operations are designed, built, and serviced in-house. This enables us to monitor every step of the process and further guarantee the precision and quality of your machined parts. All tooling is custom-built for each project, and we service and maintain your tooling for the life of your program, whether you need ten thousand parts per year or a million.
