Flat and accurate.
At Axxicon, lapping is used in conjunction with other finishing processes, such as polishing and grinding, to achieve the desired finish on tooling parts. We have extensive experience in lapping a wide range of materials to achieve the precise dimensional tolerances and surface finish required.
Our lapping process achieves exceptional flatness and accuracy. we deliver surfaces with extreme flatness and tight tolerances, ensuring optimal functionality and perfect mating of components. By reducing friction end eliminating surface imperfections, lapping enhances the longevity and reliability of mechanical parts and assemblies.
Combining cutting-edge lapping technology with 75 years of experience, our skilled technicians deliver precision and quality.
Lapping at Axxicon is a precision finishing process that involves rubbing two surfaces together with a fine abrasive paste in between them. The back-and-forth motion of the workpiece during lapping helps to ensure that the abrasive particles are evenly distributed across the surface being lapped, resulting in a smooth, flat finish. The process is used to achieve precise dimensional tolerances in flatness.

Lapping and polishing, while both methods are surface finishing processes, they serve distinct purposes and applications in industrial contexts.
Lapping employs a mixture of abrasive particles and a lapping plate to achieve high precision, flatness, and tight tolerances by correcting surface imperfections and ensuring uniformity, often resulting in a matte finish. This method is crucial for components like optical parts, sealing surfaces, high-precision bearings, and semiconductor wafers, where extreme flatness and accuracy are paramount.
In contrast, polishing uses finer abrasives and softer pads to enhance the aesthetic appearance of surfaces, producing a high-gloss, reflective finish. It focuses on smoothing the surface and removing minor defects, making it ideal for decorative metal parts, automotive components, optical lenses, and medical instruments. While lapping emphasizes precision and functional integrity, polishing prioritizes visual appeal and surface smoothness.
One application for lapping is the finishing of HFRR specimen. Proper lapping and finishing of HFRR specimens are critical for obtaining accurate and reliable wear and lubricity test results. At Axxicon, we understand the critical importance of proper specimen preparation as no other and are capable for finishing the specimen needed for
ISO 12156-1, ASTM D6097 and CEC F-06-A-96 test methods, used for measuring lubricity of low-suphur diesel fuel.
