Threads of quality – internal or external
Millions of external and internal threads have to be made for countless mass-produced parts in all kinds of machines and motors. In most cases manufacturers use extremely strong materials that withstand the heaviest of stresses – tempering steel, for instance. The IQ-Plus tap drill from LMT Fette illustrates the kind of innovations that the LMT developers bring to these demanding requirements. The basic idea of its "intelligent" IQ-Plus coating is astonishing. The development engineers have combined an extremely hard, wear-resistant base layer with a somewhat "softer" carbide layer. This adapts itself to the particular stresses during the run-in phase of hole tapping.
The method of cold-forming threads and profiles with roller systems, now proven millions of times over, was also developed by LMT Fette. Since that time the technology and the rolling heads have continuously been further developed and improved.
Whether for tap drilling or for chipless internal thread forming, and whether machining with cooling lubricant, using minimal lubrication or dry machining – for every method of manufacture, LMT offers you the optimum tool concept.
