New thread mills from Gühring

When it comes to hole making and threading, Gühring is an industry leader with a wide, extensive product portfolio.

Now, the product range has been expanded with the arrival of the MTMH3-Z. An expansion of the Drifter series of thread mills, the new MTMH3-Z Drifter helical drilling thread mill demonstrates impressive performance levels when processing materials up to 66HRc.

Combining core drilling and threading in a single operation, the new addition delivers excellent machining results and process reliability when wet or dry cutting all material types. With two oil grooves on the shaft to provide optimum cooling with cutting fluid or air, the range also has a left-hand cutting geometry that stabilises performance during climb milling. This is complemented by a fine-grain high-performance carbide composition that offers stability and high performance.

The carbide is characterised by its high hardness and is optimally suited for hard machining. Supplementing this is Gühring’s special temperature resistant TiSiN coating that prolongs tool life and performance whilst making wet, as well as dry machining possible. Furthermore, the MTMH3-Z Drifter incorporates a special face geometry with hollow grinding and this generates process-safe core hole drilling and thread milling possible in almost all material types.

With a shank diameter from 3mm to 12mm and a neck relief from 5mm to 40mm, the new thread milling series is suitable for creating threads from M2 to M16 on a material range that includes all steels and stainless, Duplex, cast and graphite iron, aluminium and titanium alloys. Suitable for drilling and threading holes up to 2.5xD in a single operation, the MTMH3-Z Drifter can drastically reduce set-ups, cycle times, tool inventory and costs for end-users.

CNC Guhro thread mill software
To simplify the process further, Gühring has also developed its CNC Guhro thread mill software that is free to download for Gühring customers.

This innovative software enables users to specify the thread data by selecting from all current thread standards and then inputting the material to be machined. At this stage, the software provides the optimal parameters.

The software also allows users to record the CNC data according to their required milling strategies and parameters. From here, users receive the desired CNC programming code and datasheets. The user simply has to import the programming data that is automatically recognised in CNC control units such as Siemens Sinumerik, Heidenhain, Fanuc, Philips, Mazatrol or Hurco.
