CeramTec’s tools designed for boring cast iron workpieces can be fitted with SPK® mixed ceramics, CBN, oxide ceramics, silicon nitride ceramics, cermets and coated versions.
Boring cast iron workpieces of the type gray cast iron and ductile cast iron takes on a whole new dimension when SPK® cutting materials are used together with the matching boring tool system: In both series and mass production it is possible to achieve cutting values with vc > 1,000 m/min and feed rates > 0.14 mm/z with process reliability. Other advantages include adherence to the tightest tolerances for dimensions and shape. The following machining steps can be shortened or completely eliminated in most cases.
