Quality Assurance Through Advanced Measurement Technology
Quality control forms the foundation of our precision CNC machining services. Our investment in advanced measurement technology demonstrates our commitment to delivering parts that consistently meet or exceed your specifications.
Our quality assurance capabilities include:
- Mitutoyo CRTPM574 CMM for detailed dimensional verification
- Hexagon Global S 07.10.07 Automated CMM for high-volume inspection efficiency
- TESA Electronic Height Gauges for rapid dimensional checks
- Comprehensive first article inspection reports
- In-process quality monitoring protocols
This sophisticated measurement infrastructure enables us to maintain true position tolerances of 0.002 inches for standard holes and surface-to-surface tolerances of ±0.0005 inches for dimensions under 6 inches. For larger dimensions exceeding 6 inches, we maintain ±0.001-inch tolerances, ensuring your parts meet the most demanding specifications.
Graphicast’s Engineering Staff & Software Capabilities
Our entire engineering staff brings years of relevant experience to every project, offering consultation and collaboration throughout the manufacturing process. We understand that successful CNC machining services require more than just equipment; they demand expertise in design optimization, material selection, and process refinement.
Engineering Software:
- SolidWorks
- CREO
- FeatureCAM
- Predator
We work seamlessly with your existing CAD files using our comprehensive software suite, ensuring smooth data transfer and eliminating potential errors that can occur during file conversion. Our engineers can review your designs for manufacturability, suggest modifications to reduce costs without compromising quality, and optimize tool paths for efficient production.
The combination of engineering expertise and advanced software capabilities allows us to tackle complex projects that other machine shops might find challenging. Whether you’re transitioning from prototype to production or need assistance optimizing an existing design, our team provides the technical support necessary for project success.
Single Source Services and Finishing Options
Beyond precision CNC machining, we offer comprehensive value-added services that eliminate the need for multiple vendors, streamlining your supply chain. Our single-source approach ensures consistent quality across all operations, simplifying your vendor management requirements.
Single Source Services:
- Painting
- Chromating
In-House Capabilities:
- Dot peen part marking for permanent identification
- De-burring and tumbling with both plastic and ceramic media
- Light assembly services, including pins, PEMs, bushings, and bearings
Additional Finishing Options:
- Powder coating through trusted partners
- Protective finishes
- Cerakote and e-coat applications
These integrated services mean you receive fully finished parts ready for implementation, reducing your administrative burden and accelerating time to market.
ISO 9001:2015 Certified Quality Management
Our ISO 9001:2015 certification represents more than compliance; it demonstrates our systematic approach to quality management and continuous improvement. This certification covers both our casting and precision machining operations, ensuring consistent quality across all services.
The ISO framework guides our processes from initial quote through final delivery, encompassing material traceability, process documentation, and comprehensive quality records. Every part we produce is backed by our quality management system, providing you with confidence in our ability to consistently meet your requirements.
Ideal for Low to Medium Volume Production
Our CNC machining services excel in the economically challenging space of low- to medium-volume production, typically ranging from 100 to 20,000 parts annually. Unlike high-volume operations that require significant minimum orders, we’ve structured our operations specifically for smaller production runs without sacrificing quality or cost-effectiveness.
This specialization enables us to offer competitive pricing for prototype development, pilot production runs, and low-volume ongoing requirements. Our setup procedures, tooling strategies, and scheduling systems are optimized for quick changeovers, allowing us to transition efficiently between different projects while maintaining precision and quality.
For companies seeking an alternative to expensive in-house machining or high minimums with offshore suppliers, our services provide the perfect balance of quality, flexibility, and cost-effectiveness. We understand the unique challenges of low-volume manufacturing and have developed our processes specifically to address these needs.
