Precision in the Final Finish
Surface Perfection Through Controlled Abrasion
At A1J Technologies, our lapping services deliver the tightest tolerances and smoothest finishes achievable in precision manufacturing. Using fine abrasive compounds and specialized equipment, we remove minute amounts of material to achieve exact surface flatness and mirror-like finishes.
Lapping is ideal for components where surface perfection directly impacts performance—such as sealing interfaces, optical assemblies, and high-precision mating parts. Our team combines experience, specialized tooling, and rigorous inspection to ensure every part meets your exact specifications.

Precision Finishing for All Scales
Our lapping systems are capable of producing ultra-flat surfaces across a wide range of component sizes.
- Workpieces up to 24″ in diameter
- Micron-level control of thickness and parallelism
- Ideal for small components, wafers, and sealing surfaces
- Suitable for both prototype and production quantities

Applications Built on Accuracy
Advanced Grinding for Critical Applications

Surface Finishing at the Micron Level
Our lapping systems are capable of producing finishes as fine as Ra ≤ 0.1 µm with thickness control measured in microns. By combining controlled pressure, rotation, and abrasive slurry selection, we deliver parts that meet the highest standards for sealing, mating, and optical applications.
We handle materials such as stainless steel, titanium, aluminum, inconel, ceramics, and specialty alloys—each processed under strict environmental and measurement controls. Our team ensures that every component meets exacting tolerances for flatness, smoothness, and parallelism before it leaves our facility.
