COST-EFFECTIVE AND STABLE
Walter AG maximises process reliability and productivity with its new copy turning system
With the W1011-P, Walter is bringing a copy turning system to the market which will maximise process reliability and cost-efficiency compared to conventional systems. This is primarily thanks to its much greater stability when copy turning with relief grooves of up to 50°. Unlike VCMT and DCMT inserts, the system’s new three-edged WL25 indexable inserts are precisely secured in the toolholder by a prism in the insert seat and on the insert itself. This ensures that the insert cannot move in the toolholder. In addition to high process reliability and precision thanks to highly accurate indexing – both when turning the inserts to the next cutting edge and when replacing them – this provides over 50% greater accuracy when compared to ISO inserts. In addition, the system has an increased tool life thanks to the option to machine in both directions of movement, meaning that the two cutting edges can be used.
The copy turning system also uses WL25 indexable inserts, which further increases its cost-efficiency. Three cutting edges (rather than two cutting edges on VCMT inserts) with wear-resistant cutting tool materials in addition to precision cooling improve the tool life. The same also applies to the universal usability of the W1011-P system. Its four insert types (neutral, left-hand, right-hand and full-radius versions) for different profiling angles and applications fit into the same toolholder and mean that it can be used for all ISO materials (P, M, S and K). Potential areas of application include copy turning (for example, for drive shafts, ball bearings, valves, etc.) and dynamic turning – particularly for operations which use a different or alternating machining direction. This allows users to increase cost-efficiency by up to 75% in finishing up to medium machining operations.

50% LONGER TOOL LIFE FOR TURNING
Walter Tiger·tec® Gold grade with multi-layered, highly textured MT-TiCN coating
With the WPP10G, WPP20G and WPP30G grades, Walter presents the new Tiger·tec® Gold indexable inserts, specially designed for turning operations. The aim was to reduce flank face wear by 30 to 60%. In reality, the tool life increased by an average of 50% according to the results of over 130 customer tests. The primary application is steels with a tensile strength of 600 to 900 N/mm2. The lightweight components made of steels with a high tensile strength of 1000 to 1400 N/mm2, which are on trend at the moment, can also be machined with the new grade. The indexable inserts are sure to be of particular interest to mass producers in the automotive, energy and general mechanical engineering sectors, where the inserts significantly reduce the cost per component. Wherever a range of materials are used, such as in the mechanical engineering industry, users can benefit from their versatility: Walter is bringing the grades with nine geometries for optimised chip breaking on long-chipping, low-carbon materials (MP3) and for interrupted cuts (RP7) to the market.
Another key feature of the Tiger·tec® Gold inserts for turning is their outstanding process reliability. This, alongside their performance and tool life, is the result of their unique layer structure: A patent-pending, highly textured MT-TiCN layer reduces flank face wear and increases toughness due to its multi-layered structure, which optimises elasticity. The highly textured Al2O3 layer additionally increases the product’s resistance to crater wear. The gold-coloured top layer improves wear detection. The final multi-stage post-treatment of the inserts ensures a smooth rake face, less friction and high level of toughness. The individual alignment of the grades makes the indexable inserts outstandingly versatile: WPP10G for continuous cuts and light interrupted cuts, WPP20G as a universal grade for 50% of applications and the tough WPP30G grade interrupted cuts as well as unstable or unfavourable conditions.
