Comprehensive Metal Finishing
Services for Precision and Quality

As part of our full-service approach, Precision Resource offers a full range of high-precision finishing services to ensure that every component meets the exact specifications required for integration into final assembly. From refining surfaces to enhancing durability, our advanced finishing capabilities add value at every stage of production.

CNC Machining

Our CNC machining capabilities provide the precision and consistency needed to refine components to exact specifications. Using advanced multi-axis CNC mills, lathes, and technology, we achieve tight tolerances, complex geometries, and superior surface finishes. This process enhances functionality, reliability, and overall performance, making our components production-ready. Learn more about our CNC machining services.

Surface Finishing

To meet strict flatness, thickness, and surface finish requirements, our range of surface finishing techniques, including conventional grinding, fine grinding, and lapping allow us to refine component surfaces to the highest standards. Our conventional grinding methods – double-side, single-side, through-feed, plunge, and rotary carousel – deliver cost-effective improvements in flatness and finish. Fine grinding uses fixed abrasives to achieve tolerances and finishes comparable to lapping while eliminating cleanliness concerns. Lapping, available in both double-side and single-side processes, ensures exceptional precision for critical applications.

Heat Treating

Many of the components we manufacture require post-processing heat treatment to enhance strength, hardness, and wear resistance. Precision Resource ensures precise heat treatment through a combination of internal capabilities and partnerships with approved suppliers, carefully managing the process to maintain dimensional integrity and mechanical performance. 



Our deep expertise allows us to develop optimized processing techniques that achieve the necessary material properties while minimizing distortion. We apply this knowledge to both in-house and outsourced operations, ensuring defect-free, high-quality components. 



Our Mexico division features in-house hardening, carburizing, and nitro-carburizing capabilities, utilizing two UBC batch furnaces and a continuous belt furnace for efficient high-volume production. Additionally, we offer induction hardening across multiple locations.

Laser Cutting and Laser Welding

Precision Resource’s laser cutting and welding services provide high-precision joining and shaping solutions for a variety of materials. Laser cutting delivers clean, intricate cuts with minimal heat-affected zones, preserving material integrity. Our laser welding process produces strong, seamless bonds with superior accuracy, ensuring high-performance components that meet exacting assembly requirements.

Honing, Broaching and Plastic Overmolding

We offer honing and broaching services to refine internal diameters, keyways, and other intricate features with exceptional precision. Honing improves roundness and surface finish, while broaching creates highly accurate, repeatable profiles in complex parts. Plastic overmolding enhances functionality by integrating durable polymer coatings, improving grip, insulation, or wear resistance.


Assembly

Our assembly services streamline production by combining precision components into fully integrated subassemblies. Whether through mechanical fastening, press-fitting, or welding, we ensure each assembly is built to meet specific performance and reliability standards. By delivering ready-to-install components, we help customers reduce in-house labor costs and improve manufacturing efficiency. Learn about our assembly services.

Deburring and Cleaning

Deburring and cleaning are essential final steps in preparing components for our customers, ensuring each part meets the highest quality standards. These processes remove any sharp edges, burrs, or contaminants, enhancing component safety and functionality. We offer a variety of deburring capabilities to handle the diverse requirements of the many parts we manufacture, including high-energy deburring, tumbling, polishing, belt sanding, brushing, and more, allowing us to deliver components that are free of imperfections and contamination. With our attention to detail and expertise, we confirm that every part is thoroughly cleaned and deburred to meet precise specifications.
