Lappers/Lapping Machines (also known as surface finishing machines) are used to achieve high-precision surface finishes and flatness by abrading material with a rotating plate and abrasive slurry. Commonly used in industries like optics, automotive, and aerospace, they are ideal for polishing components such as lenses, seals, and valves. Lapping machines are essential for producing ultra-smooth and precise surfaces.
