SPK® Precision Tools for Boring
Boring Tools with Fixed Insert Seatings and Cassettes
CeramTec is constantly developing new tool systems, ceramic cutting materials and insert geometries for milling operations that feature excellent performance in roughing and finishing together with safe and easy handling.
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.
