Product handbook Milling _ SILVER, BLACK, STRONG The new force in machining.

Yesterday, it was machining. Today, it s tigering. Cutting tool materials with the Tiger tec technology brand are setting the standard in machining again and again, in terms of productivity and process stability. With the new cutting tool material, the engineers at Walter have moved another great step closer to the ideal cutting tool material. is ideal for dry and wet machining of steel and cast iron materials, and is at home in important key sectors: the automotive industry and rail vehicle manufacturing, power engineering, the aerospace industry, mechanical engineering and in mold and die making.

The new technology New Tiger, new benchmark: Up to 100 % increase in output Extremely stable cutting edges for high level of process reliability Extremely smooth rake face for excellent wear resistance Silver colored flank face for extremely easy wear detection during use 2

Unique throughout the world With its globally unique CVD coating technology, the cutting tool material is forging ahead into new dimensions. In day-to-day manufacturing, this means that increases in output of up to 100 % are possible in machining. Other features of : Enormous toughness and minimal formation of hairline cracks thanks to optimum residual strength Greatly reduced tribochemical wear thanks to perfect, smooth rake faces Not susceptible to thermal stress variations during wet and dry machining Completely new CVD coating technology: Combines wear resistance and toughness For steel and cast iron workpieces Optimum friction behavior -Al 2 O 3 MT-Ti(C, N) Substrate Greater resistance to flank face wear Excellent hardness to toughness ratio 3

The new technology High level of wear resistance A close-up view of the cutting edges shows it clearly: the new cutting tool material can easily handle even the most difficult machining conditions thanks to its new, revolutionary coating. Hairline cracks, such as those that occur at high cutting speeds, with interrupted cuts and difficult cutting conditions in particular, are decisively reduced with indexable inserts. In the example shown, heat treatable steel 4140 was milled twice, with the existing insert and with the new. With the indexable insert, the high level of wear resistance, the toughness and resistance to temperature reduce negative hairline crack formations and chipping, and therefore costly reductions in service life. Existing 4

Outstanding properties PRODUCT PROPERTIES: Performance increase of up to 100 % Thanks to excellent wear behavior combined with extreme toughness Excellent cutting and chip evacuation behavior Thanks to extremely smooth rake faces Resistant to deformation and oxidation wear Thanks to the new type of aluminum oxide coating Benefits for you: Low production costs Higher cutting speeds thanks to heat-resistant coating High level of process reliability High level of toughness thanks to technology Improved chip flow thanks to extremely smooth rake faces Low cutting material costs Excellent wear detection thanks to indicator coating Unused cutting edges not wasted High level of resistance to flank face wear Thanks to fine-grained, columnar, average temperature titanium carbonitride New dimension in the toughness to wear resistance ratio Thanks to the new type of coating technology 5

Applications and examples THE APPLICATION With the new technology, there is also completely new surface treatment in addition to the special coating combination. Due to the optimal residual stresses, the toughness of the wear-resistant cutting tool material increases exponentially. It is this combination of a high level of wear resistance and toughness that gives superior machining performance.

Technical Information Problem solving Formation of hairline cracks Flank face wear Feature In relation to the cutting edge, vertical small cracks that can result in chipping along the edge and fractures in the indexable insert. Cause Formation of hairline cracks resulting from stresses caused by changes in temperature Due to an interrupted cut (brief contact time between cutting edge and workpiece, long cooling phase) Use of coolant (thermal shock) Remedy / measure(s) Try working without coolant Use a tougher cutting material Reduce the cutting speed Feature The most frequently occurring type of wear, affecting the flank face. Cause Caused by abrasion between the flank face and workpiece During roughing, this often leads to vibrations and increased capacity requirements. During finishing, it can lead to poor surfaces Remedy / measure(s) Use a wear-resistant cutting material Reduce the cutting speed Increase the feed 78

Chips along the edge Plastic deformation Feature Chipping along the edges of small sections of the cutting material in the cutting edge. Cause Mechanical overload leads to small sections of the cutting material in the cutting edge breaking off May be a result of hairline cracks Remedy / measure(s) Select a more stable geometry (longer removal phase) Ensure a stable machining process Use a tougher cutting material Feature Cutting edge deformed in some other, undefined manner. Cause Occurs at high machining temperatures in conjunction with a high mechanical load, because of softening and yielding of the cutting tool material Leads to a sudden and sharp increase in the machining temperature and cutting force, fluctuations in dimensions and poor surfaces on the component, and sometimes fractures in the cutting edge Remedy / measure(s) Use a wear-resistant cutting material Reduce the cutting speed Reduce feed 79
