Abstract
The utility model relates to a right-angled plane hobbing which uses four-corner blade to process a vertical step surface, wherein, four common (1) blades on the cutter body are fastened in the four cutter grooves of the cutter body by four double-end screws and wedge blocks. A common blade and a smoothing blade are fastened in another cutter groove by a double-end screw and a wedge block. A cutter disk of the smoothing blade is provided with a wedge-shaped groove (7), and the inner part of the cutter groove is deepened 0.2 millimeters in a radical direction; thus, after the positioning is assured, an entering angle is 87 DEG, axial protrusion is 0.2-0.3 millimeters, and radical retraction is 0.2 millimeters. An included angle between the main cutting edge and the radical direction is 15 DEG, and the cutter disk and the cutter body are connected together by five M8 screws.
Description
The present invention relates to a kind of indexable right angle face mill of side set that uses positive four jiaos of carbide chips of processing metal vertical stand terrace, use when especially adapting to the roughing of vertical stand terrace.
Existing known on the right angle milling cutter of competent big cutting output processing metal vertical stand terrace, the blade of paperback is triangle or rhombus.When the cutting edge equal length, triangular blade is big not as four jiaos of blades and cutter hub contact area, and it is good that the poor reliability of clamping, the intensity of cutter hub own also are not so good as four jiaos of blades; Diamond shaped insert can only be used two acute angle cuttings owing to be subjected to the restriction of geometric angle, has reduced the blade utilization rate.
The right angle milling cutter that the positive four jiaos of blades of paperback carbide alloy on the milling cutter tooth are also arranged at present, but the negative bias angle of cutter tooth must be zero degree or negative value, this just causes the whole pair of cutting edge will be in working angles, friction on finished surface, the very big heat of generation, reduced the durability of blade, and cause vibrations easily, the roughness of finished surface is worsened.
The face milling cutters that the purpose of this invention is to provide the processing right angle platform terrace of four jiaos of carbide chips of a kind of use, it can prevent in working angles effectively, and front cutting edge and finished surface friction produce very big heat, thereby improved the durability of blade, improved machined surface roughness.
The object of the present invention is achieved like this:
Right angle face mill uses six four jiaos of blades, and one as the smoothing tooth, and five as full depth tooth, has five cutter grooves by what radial width equated on cutter hub; Wherein in four cutter grooves, four ordinary blades are fastened in the cutter groove of cutter hub by dowel screw, voussoir; In another cutter groove, a full depth tooth blade and smoothing teeth cutter blade are housed simultaneously; Two blades are with being fastened in the cutter groove of cutter hub by a dowel screw, a voussoir; But the inclined-plane of fastening smoothing teeth cutter blade voussoir radially becomes 15 ° of angles with cutter hub; And on the cutterhead bottom surface as datum level, for the smoothing teeth cutter blade is opened a wedge-like groove, width is identical with blade thickness, direction also radially becomes 15 ° of angles with cutter hub, after wedge groove depth capacity will satisfy smoothing teeth cutter blade location, tool cutting edge angle is 87 °, (because of usefulness be four jiaos of blades, so auxiliary angle is 8 °.), blade is in the axial direction than five full depth tooth blades, an outstanding △ value (△=0.2-0.8 millimeter) and in the cutter groove, on smoothing teeth cutter blade position radially than 0.2 millimeter of full depth tooth indentation.
Said structure makes the smoothing tooth not participate in radial cutting, and full depth tooth is not participated in axial cutting, and axially the smoothing cutting is then finished by the wiper edges of smoothing tooth separately, has guaranteed the roughness requirement of machined surface.
So just having solved because of the positive four jiaos of blades of paperback, is the contradiction of zero degree or negative value and make the negative bias angle of right angle face mill, can obtain four transpositions, can process accurate right angle platform terrace again.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.Accompanying drawing 1 is the concrete structure figure of embodiment;
Accompanying drawing 2 is that A-A is to cutaway view;
Accompanying drawing 3 is that Q is to expanded view;
After accompanying drawing 4 is smoothing teeth cutter blade and full depth tooth blade location, radially, the axial location comparison diagram.
Disc cutterhead (6) and cutter hub (5), connect together by five M8 screws (8), the radially first-class width of cutter hub (5), equidistantly have five rectangular aperture cutter grooves, full depth tooth blade (1) is fastened in the cutter groove of cutter hub (5) by dowel screw (3) voussoir (2) in four cutter grooves, corresponding main cutting edge has arc chip area (9) on cutter hub.Main cutting edge, cutter hub radially angle are 0 °; In the remaining cutter groove, utilize same dowel screw (3) voussoir (2) simultaneously a full depth tooth blade (1) and a smoothing teeth cutter blade (4) to be fastened in the cutter groove of cutter hub (5), but the gradient of voussoir (2) one end faces should guarantee full depth tooth blade (1) main cutting edge (10) and cutter hub (5) radially angle be 0 °; Other end inclined-plane gradient guarantees that then smoothing teeth cutter blade (4) main cutting edge (10) and the radially angle of cutter hub (5) are 15 °, and this voussoir (2) has arc chip area (11).
Cutterhead (6) is gone up corresponding smoothing teeth cutter blade (4) position, is processed with radially the wedge-shaped slot (7) at penta 15 ° of angles, and the width of groove equates that with blade thickness the degree of depth is to guarantee an axial △ value, the △=0.2-0.8 millimeter of giving prominence in back, smoothing teeth cutter blade (4) location; The cutter groove is radially deepened 0.2 millimeter, and after this had just structurally guaranteed wiper inserts (4) location, 87 ° of tool cutting edge angles, auxiliary angle were 8 °, and the footpath is upwards than 0.2 millimeter of full depth tooth blade (1) indentation, wiper edges L=2 ± 0.3 of smoothing teeth cutter blade (4) millimeter.
Claims (3)
1, use positive four jiaos of carbide chips, processing vertical stand terrace, the indexable right angle face mill of side set, it is made up of cutter hub [5], cutterhead [6], dowel screw [3], voussoir [2], wiper inserts [4], ordinary blade [1], it is characterized in that: radially wait width to have five opening cutter grooves on the cutter hub [5], in four cutter grooves, ordinary blade [1] is fastened on the cutter hub [5] by dowel screw [3], voussoir [2]; In the remaining cutter groove cutter, an ordinary blade [1] and a wiper inserts [4] are fastened on the cutter hub [5] by dowel screw [3], voussoir [2].Cutter hub [5] is connected together by five M8 screws [8] with cutterhead [6].
