Description
Technical field
The present invention relates to a kind of method for grinding of milling cutter anterior angle.
Background technology
Milling cutter is a kind of conventional new structure cutter of Digit Control Machine Tool processed complex curved surface, Making mold, automobile making,
The industries such as space flight and aviation, electronic communication product manufacture have a wide range of applications.
The anterior angle of milling cutter seen by present typically carries out grinding using four-axle linked following simple grinding equipment and added
Work is formed, and its ball sword is flush cut sword, and ball angle of cutting edge is negative rake or part negative rake, and anterior angle and Zhou Ren (i.e. circumferential parts
Point cutting edge, the circumferential section of milling cutter is cylinder, and the circumferential section of milling cutter is circular cone) anterior angle is not smoothly connected, such anterior angle
Milling cutter in process, is also easy to produce vibration, cuts phenomena such as unstable, chip removal is not smooth, with the Product Precision and matter of its processing
Measure poor, use occasion is restricted.Another kind of grinding processing method is sharpened using five-axle linkage grinding machine tool.Should
The five-axle linkage of class grinding machine tool is used and linked between two rotary shafts and three shifting axles, equipment complex designing, equipment
The accuracy of manufacture requires high, and manufacture difficulty increases, and causes equipment price height.Buy that the investment of the kind equipment is big, cause the life of milling cutter
Production and sharpening cost are high.
Again because no Special clamping has, taper reamer is controlled manually, carries out the grinding of anterior angle, cutting edge is everywhere after grinding
Tooth depth, not only presentation quality is bad, and influences Tool in Cutting processing effect.In order to meet actual processing needs, improve
The machining status is, it is necessary to develop a kind of grinding taper milling cutter anterior angle specific purpose tool.
The content of the invention
It is an object of the invention to provide one kind is not likely to produce vibration in process, working angles are steady, chip removal is suitable
Smooth milling cutter, independent of the equipment of complex and expensive, grinding can be completed with existing simple machine, and its precision is not affected by
Any influence.Concrete technical scheme is as follows：
A kind of grinding process of milling cutter anterior angle, comprises the following steps：
(1) milling fixture is arranged on the workbench of lathe and positioned using two bolts, parallelism error exists
Within 0.001mm, flatness error is within 0.001mm；
(2) it is fixed with milling fixture by screw after adjusting milling cutter position；
(3) swinging milling handle makes the axis of milling cutter and milling fixture simultaneously around two bolts rotate in fixed axis；
(4) anterior angle emery wheel is set above fixture and milling cutter, and anterior angle emery wheel is arranged on angle adjusting seat so as to around vertical
Directly being rotated in the horizontal plane in the axis of horizontal plane to adjust the angle of grinding wheel spindle and milling cutter, emery wheel sets two main shafts, and first
The CBN emery wheels that main shaft installation granularity is 120#, emery wheel is resinoid bond straight-type wheel, a diameter of Φ 100mm, grinding speed
For 30m/s, amount of feeding 50mm/min, grinding depth 0.1mm, blade is beated within 0.01mm, circumferential teeth etc. point control
Within 0.01mm, the second main shaft installation 12V9RVD emery wheels, its is a diameter of Granularity is 120#, rotating speed 75000r/
Min, the first and second main shafts are pivotally connected to reducing gear by transmission, and are connected to motor；
(5) protective hood of grinding wheel is set；
(6) location-plate is bolted to milling fixture；
(7) bulk-breaking is set etc. according to the number of teeth of milling cutter and waits the isodisperse of bulk-breaking；
(8) using holding screw will etc. after the adjustment of bulk-breaking and milling cutter it is fixed；
(9) foregoing screw and holding screw are fastened；
(10) anterior angle of one cutter tooth of wheel grinding is used；
(11) alignment pin that bolt extracts location-plate is unclamped；
(12) rotary cutter and location-plate, alignment pin is inserted in another grade bulk-breaking hole adjoined；
(13) screwing bolts, it is ground the anterior angle of two cutters tooth and circulates all cutter tooth anterior angles of grinding；
(14) detect, cleaned when reaching grinding and requiring, be ground again when not required up to grinding；
(15) coating treatment is carried out with TiN coating materials.
Make milling fixture axial line in step (3) with loading the axially bored line of handle of a knife at grade.
Step also includes in (4)：Emery wheel is grinding into the shape of spherical radius needed for Design Milling.
Adjustment uses following steps described in step (5)：
(5-1) rotates milling cutter or moves axially milling cutter；
(5-2) with the inspection of edge of a knife chi, control blank cutter tooth allowance uniformity；
(5-3), which rotates milling cutter, makes before a certain cutter tooth cutting edge be slightly higher than the plane on clamp body, difference for grinding anterior angle plus
Spare time measures.
Make the centre of sphere of cutter tooth blank in step (7) by the axial line of jig main body, and during the bulk-breaking such as alignment pin insertion
It is vertical with the axial line of jig main body before the blank of one cutter tooth.
Adjustment uses following steps described in step (7)：
(7-1) positions fixture according to milling cutter and grinding demand on the table；
(7-2) unclamps holding screw and screw；
(7-3) rotates milling cutter, moves axially milling cutter；
(7-4) with the inspection of edge of a knife chi, control blank cutter tooth allowance uniformity；
(7-5) rotates the plane for the clamping milling cutter that milling cutter makes cutting edge before a certain cutter tooth be slightly higher than fixture.
When the helical pitch that cutter presses blade helix is for the helical movement, the cylindrical envelope of emery wheel large end face goes out the preceding knife of cutter
Face, while the outer conical surface envelope of emery wheel goes out cutter helicla flute.
Compared with currently available technology, equipment of the present invention independent of complex and expensive, it can be completed with existing simple machine
Grinding, and its precision is not affected by any influence.Using special micro mist emery wheel, the cost of emery wheel has greatly been saved.It is vertical
Process time is greatly reduced compared to flat surface grinding in formula grinding, improves production efficiency.Main shaft high-speed rotation, grinding lines is in side
Cyclization around shape, is reduced due to being occurred the situation of micro-crack by unbalanced stress on knife face after sword.Special fixture used can show
Write positioning precision when improving grinding；Step of the present invention is reasonable in design complete, and feasibility is high.
