Tap's Chipbreaking Geometry Promotes Versatility, Reliability
The Hoffmann Group has added the MasterTap high-performance tap to its Garant Master tool series. This product is the result of a development concept for the design of universal taps, achieving high process reliability and efficiency in a wider range of materials including steel, stainless steel, aluminum, brass and cast iron.
The key to MasterTap’s versatility is its effective chip removal enabled by a new cutting edge geometry as well as optimized flutes. These features are said to consistently eliminate winding chips and loose swarf.
When reversing in blind-hole machining, the Garant MasterTap promotes reliability by shearing off chips and smoothing the chip roots with a specially-designed tooth back. The tool excels in particular when machining high-strength steel materials thanks to its rounded cutting edges, according to the company. This rounding also insures defined and continuous wear behavior without breakouts and thus a longer service life.
The tool’s HSS-E-PM cutting material and AlTiX coating help it to achieve high performance and longevity. The ultra-smooth coating protects against premature wear and enables high cutting speeds, even in aluminum-wrought alloys, because the low friction values prevent material sticking and thread corrosion. Thanks to its special guide thread, the tool achieves precise results without axial slicing even in ductile copper alloys.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
Drill more productively by making a few strategic changes to the process. Those same changes may also let you drill dry.
Let's face it. When most shops go looking for process improvements, turning is seldom at the top of the list. Sure, many shops these days are doing fine work in such areas as reducing lathe setup, combining milling and turning operations on a single machine, and automating workpiece handling functions. But for all the talk of high speed machining and other milling and drilling process improvements, precious little of that kind of thinking is being applied to the turning process itself.
