Technical field
The present invention relates to milling with whirling cutter technical field, refer in particular to the hard milling method of a kind of leading screw or worm screw.
Background technology
In the mid-90 in last century, high-speed milling technique is introduced into Making mold, is particularly a major transformation of technology of die manufacturing with firmly processing that the high-speed milling technology be associated applies in mold manufacturing industry.By high-speed hard milling technique, comprehensive process is carried out to the mould under clamped one time, not only process time be can significantly reduce, the surface quality of profile and machining accuracy improved, and can the technological process of production be simplified, thus significantly shorten the manufacturing cycle of mould, reduce the production cost of mould.
Adopt high-speed hard milling processing mold, in most cases can save and manufacture electrode, spark machined and polishing three process.At the end of the nineties, high-speed hard milling instead of spark machined in many processing occasions (except the interior angle processing of some narrow slits, deep trouth and minimum radius).But existing hard Milling Process is difficult to leading screw or the worm screw of producing high slenderness ratio, cause the leading screw of high slenderness ratio or the processing cost of worm screw and production efficiency to remain high always.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hard milling method reducing manufacturing procedure, raising crudy and production efficiency for leading screw or worm screw, except saving cutter expense, also reduce number of changing knife, thus decrease the non-cutting time of 30%, whole process time only needs 99 minutes, and process time decreased 26% than originally.Add and adopt micro lubricating man-hour, decrease tool wear.。
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The hard milling method of a kind of leading screw or worm screw, whirling mill cutterhead adopts alloy milling cutter, tell that Milling Process obtains leading screw or worm screw to the steel column after quenching, the hardness of described alloy milling cutter is 58 ~ 68HRC, and cutting speed during Milling Process during the hard milling of alloy milling cutter is 200 ~ 350m/min.
Preferably, the cutterhead external diameter of described whirling mill cutterhead is 150 ~ 155mm, and during Milling Process, the rotating speed of whirling mill cutterhead is 450 ~ 700r/min.
Preferably, the hardness of described alloy milling cutter is 60HRC, and cutting speed during Milling Process during the hard milling of alloy milling cutter is 300m/min.
Preferably, the feed of every rotation of described whirling mill cutterhead is 0.1mm ~ 0.2mm.
Preferably, described alloy milling cutter is made up of CBN material.
Preferably, on described whirling mill cutterhead, the quantity of milling cutter is 12 or 16.
Beneficial effect of the present invention is:
The invention provides the hard milling method of a kind of leading screw or worm screw, whirling mill cutterhead of the present invention is carrying out in Milling Processes, high temperature is produced when alloy milling cutter high-speed cutting leading screw or worm screw, 40HRC or lower is reduced at high operating temperatures by the cutting place hardness of milling workpiece leading screw or worm screw, and now, the hardness of the alloy milling cutter adopting CBN material to make still can remain on the hardness close to 60HRC, the difficulty of processing of milling is greatly reduced when carrying out milling in this condition, reduce alloy milling cutter wearing and tearing and by the mismachining tolerance of milling workpiece leading screw or worm screw, extend the service life of milling with whirling cutter cutterhead and alloy milling cutter, machining accuracy is higher, practicality is stronger.
