Info v c / f z Product Finder 4.1 Characteristics and advantages of thread milling Thread milling – A technology which can reduce your production costs considerably! With the more and more widespread use of CNC technology, the basic conditions for a future-oriented technique of producing internal and external threads have been created. Thread milling can be practiced without any trouble and with a high degree of process safety if your CNC machine is provided with a control for 3D-interpolation. In addition to that, you need stable and vibration-free tool and workpiece clamping, and internal coolant supply. In case you should have little or no experience with the programming of the control, our technicians will be happy to help you by word and deed. We are also ready, at any time, to provide in-house or on-location training for you with practical machining examples. Please contact our sales personnel. Thread milling is, in a multitude of application cases, a highly recommendable alternative to tapping or cold-forming of threads, with the following advantages: • Short production times • High degree of process safety • Very good surface quality • Combination of different machining jobs with one tool • Usable thread depth down to the very bottom of the hole • No expensive lubricants are needed • No chip problems, since only short milling chips are created • No axial miscutting (overcut) of the thread • Universal use in the most different materials up to approx. 60 HRC • Blind hole and through hole threads produced with one tool • Thread production independent of thread size and tolerance • One tool only for right-hand and left-hand threads • Low cutting forces • Suitable also for thin-walled components 4.2 Our EMUGE thread mill types BGF Solid carbide drill thread mills • For the production of internal threads • For the complete machining of thread hole, chamfer and thread in one work process • Tool for one single thread size with corrected thread profile Designs: 2-fluted: For work in solid material 3-fluted: For work in pre-cast thread holes and in solid material ZBGF Solid carbide circular drill thread mills • For the production of internal threads • For the machining of thread hole and thread in one work process • Tool for different thread sizes but for one pitch only, with corrected thread profile Designs: ZBGF-T: For thread depths up to 3 x D in aluminum and cast iron ZBGF-H: For hard machining from 44 HRC ZBGF-W: For the most different materials up to 44 HRC
