Lapping: Lapping is a precision machining process that involves rubbing two surfaces together with an abrasive slurry between them. This process is used to flatten, smooth, or refine the surface of a workpiece to achieve tight tolerances and improve surface finish. Lapping removes material from the workpiece surface through abrasive action, typically using abrasive particles suspended in a liquid or paste. The process is performed using specialized lapping machines equipped with flat lapping plates or wheels. Custom lapping services tailor the lapping process to meet specific dimensional requirements, surface finish specifications, and material properties of the workpiece. This may involve selecting the appropriate abrasives, lapping compounds, and process parameters to achieve the desired results.

Polishing: Polishing is a finishing process that involves smoothing and shining the surface of a workpiece to improve its appearance, reflectivity, and surface quality. Polishing removes surface imperfections, scratches, and roughness, resulting in a smooth, glossy finish. Polishing can be performed using abrasive materials such as polishing compounds, pads, or abrasive slurries applied to rotating polishing wheels or belts. The process may also involve chemical or electrochemical polishing techniques for specific materials. Custom polishing services cater to the unique requirements of each workpiece, including surface finish specifications, material composition, and application-specific criteria. This may involve selecting the appropriate polishing materials, techniques, and equipment to achieve the desired surface characteristics.

Quality assurance: Custom lapping and polishing services often include stringent quality control measures to ensure that the finished components meet customer specifications and industry standards. This may involve precision measurement and inspection techniques, such as surface profilometry, optical metrology, and visual inspection, to verify dimensional accuracy, surface finish, and overall quality.
