Cutting Materials
Added value with SPK cutting materials.
Due to unbeatable wear resistance hardness and hot hardness SPK-Ceramics established itself as an ideal cutting material for mass production of cast iron parts, hard rolls and hardened steel. Machining speed is increased, production time shortened, output, productivity and efficiency are highly improved.
A wide range of products for SPK-WURBON® is completing the range of cutting materials for high performance machining of cast iron and hardened steel.
SPK-Cermets achieve best surface qualities and dimensional accuracy of the work pieces in finishing steel. They are ideal suited for finishing and fine finishing operations with low chip cross sections and uniform depths of cut.
SL 500
Universal silicon nitride grade particularly suited for roughing and finishing of grey cast iron materials performed with both continuous and interrupted cuts.
SL 808
This new silicon nitride is ideal suited for high-performance rough milling of cast iron, The outstanding wear resistance in combination with excellent toughness promise good process reliability under the roughest conditions.
SL 854 C
is a coated all purpose milling grade for roughing and finishing operations of cast and ductile cast iron.
SH 2
Grade offering an extremely homogenous submicron structure which enables high mechanical and thermal resistance and highly precise cutting edges. Mixed ceramic grade for hard fine machining in continuous cutting.
WBN 100
Poly crystalline boron nitride for milling of chilled cast iron, hardened cast iron, sintered metals and hard coatings.
SC 7015
SPK-Cermet grade with an Al2O3 coating. Its main applications is finish turning and semi rough turning of cast iron and steel at elevated cutting speeds.
SC 60
SPK-Cermet grade for finishing to light rough milling steel and ductile cast iron.
