circular and thread milling advantages of thread milling different diameters and independent tolerances a tool for right and left hand threads no tool holding problems no tool holder changes required no axial deformation of threads small deviation with thin-walled workpieces clean thread flanks full thread to core hole depth easy processing of difficult to machine materials through and blind hole application reduced pockets in tool carousel no reverse and return delay short cycle times due to high speed and feed with conical threads no root diameter remains high positional accuracy following a tool failure problem-free removal of the tool from the workpiece 6 application tips part 1 with thread milling there are two different programme possibilities with the feed motion of the tool on the one hand the machine controls the feed at the diameter of the tool on the other hand the feed control is the tool center line in order to ascertain which method the machine control uses the following method should be employed enter the thread milling routine into the control enter a safety margin into the program so that the tool runs in air run the program through and check the operating time compare the actual time with the calculated theoretical time if the time is longer than the calculated time the feed is controlling the tool center line if the time is shorter than the calculated time the feed is controlling the diameter of the tool www.wnt.com 06 7

circular and thread milling hint for the user part 2 clamp tool with minimum overhang and maximum stability to achieve good runout if poor surface quality in stainless steels results change the revolution direction to attain a better cutting force situation when changing the revolution direction please take care to reposition the start position of the mill examples for right hand thread climb milling from the bottom to the top conventional milling from the top to the bottom if possible start with a 90° or 180° ramp in the milling direction to remove surface witness example of 90° example of 180° end point start point pitch pitch start point end point profile correction in order to achieve the greatest possible stability the new wnt thread milling tools are profile-corrected and possess a very favorable relationship from tool diameter to pitch for example a thread milling cutter for a metric thread m6 has a cutting diameter of 4.8 mm the pitch for such a thread is 1.0 mm which requires a pilot hole diameter of 5.0 mm the difference from drilling to tool amounts in this case to 0.2 mm i.e 0.1 mm radial clearance following the 2/3 rule a thread milling cutter without profile correction would be 3.3 mm in diameter 06 8 www.wnt.com
