After several years of development, in 2016 Schumacher brings new high-performance geometry for universal use in a wide range of materials to the market. During the course of extensive redesign and after extensive testing with leading German users, one of the strongest currently available universal geometries has emerged at a compelling price performance ratio.
Based on an analysis of the most popular materials, the F&E Team of Schumacher Precision Tools GmbH has redefined a requirement profile for a novel Universal Geometry. Objectives here had greater flexibility in use, improved tool life in a specified range of target materials and a reduction of the cost per thread for the user.
During extensive redesign, one of the strongest currently available universal geometries has emerged.
Drawing on Schumacher's design modules ToolDesign and ToolSimulation, since the end of 2013, the engineers and application engineers of Schumacher developed a tool for creating threads in the most common categories of material. Compared to the previous geometry all essential geometry parameters were devised and further developed. In addition to design and relationship of web and flutes, these include the section geometry, the surface treatment and the deburring, grinding and buffing procedure.
For the new high performance geometry, the most popular materials were subjected to analysis. Compared to the previous geometry, all significant parameters were processed and developed further.
The variants were tested repeatedly in several development steps against the strongest available threading tools. With the conclusion of the project, two of the most powerful universal tools for the premium segment have emerged. Prominent features of the new design are the optimization of the ratio of thread and groove as well as the adaptation of the conicity of the threaded part. A complete renewal of the cutting geometry (as a combination of groove geometry, adjustment of cutting and clearance angles), improvement of the surface technology with tuning of the vaporization process as well as a new coordination of the grinding processes for optimized machining of target materials are equally important features of the new UNIVERSAL line of threading tools.
