CBN Lapping Ball End Mills

CBN Lapping Ball End Mills

Our CBN lapping ball end mills are intended exclusively for lapping. Used for the superfinishing process, they ensure high precision and a surprisingly shiny surface finish. Although they are intended exclusively for lapping, they ensure the same high-precision machining as standard ball end mills, with a diameter accuracy of 0µm to -3µm and a radius accuracy of ±2μm.
