Inspection capability depends on part geometry, feature size, measurement method, and required uncertainty. Using structured light scanning, J&L can verify features with tolerances as small as 5–6 microns. Our coordinate measuring machines (CMMs) can verify dimensions with accuracies supporting tolerances of approximately ±0.0005 inches. For specific applications, our team can review your drawing requirements and recommend the most appropriate inspection method.
J&L typically provides layout inspection results using AS9102 Form 3 reporting. We can also accommodate customer-specific reporting formats when requirements are provided in advance. Documentation supporting our ISO/IEC 17025 accredited laboratory is available upon request and can also be accessed through our website.
J&L is not currently NADCAP accredited for FPI. However, our quality management system and inspection processes are designed to support customer-specific requirements, and we are prepared to pursue NADCAP accreditation when supported by long-term customer demand and business requirements.
Yes. When approved tooling and work instructions are provided by the customer, J&L has successfully reworked parts that failed Fluorescent Penetrant Inspection (FPI) and helped restore them to a passing condition. Our team evaluates each situation individually to ensure all rework is performed in accordance with the customer’s specifications and quality requirements.
J&L performs precision hand finishing on a wide variety of metals and aerospace alloys, including stainless steels, nickel-based superalloys, titanium alloys, aluminum alloys, and other specialty materials. We do not currently process magnesium components.
Yes. J&L has extensive experience supporting investment-cast components through a variety of salvage and rework operations. Our skilled finishing technicians have successfully performed core-break repair, excavation preparation, weld preparation, weld blending, and other dimensional restoration activities. Each salvage opportunity is reviewed individually to determine technical feasibility and compliance with customer requirements.
Whether you need dimensional inspection, investment casting finishing, or fluorescent penetrant inspection services, J&L Dimensional is ready to support your project with responsive communication, precision workmanship, and trusted quality standards.
