Abstract
The invention discloses a step mill cutter, which comprises a cutter handle and a cutter body, wherein the cutter body is provided with a step blade and a chamfering blade; the cutter body has a spiral groove and a chute which are crossed; and the step blade is a spiral blade arranged on the groove wall of the spiral groove, and the chamfering blade is a linear blade arranged on the groove wall of the chute. In the step mill cutter, the spiral groove and the chute are formed on the cutter body to form a spiral cutting edge and a linear cutting edge, respectively, wherein the spiral cutting edge serves as the step blade of the step mill cutter and the linear cutting edge serves as the chamfering blade of the step mill cutter. Compared with the linear blade, the spiral blade has the advantages of ensuring cutting stability, enlarging the actual working rake of the cutting edge and consequently improve the processing precision and surface quality of the workpiece effectively due to the gradually-changing of the feeding and withdrawing of the cutting edge.
Description
Technical field
The present invention relates to a kind of milling cutter, especially relate to a species stage milling cutter.
Background technology
The form optical panel of digital product part extensively adopts PMMA (methyl methacrylate), PC (Merlon) material at present, and this material stock is a larger size panel, reaches the various sizes that meet the digital product designing requirement through Milling Process.This series products processes undercut ss for satisfying matching requirements when all needs are processed the edge simultaneously, as shown in Figure 1.Usual process tool and the processing mode that uses, as shown in Figures 2 and 3, remove the material of half on the top of cutter hub 100, processing generates the plane cutting edge on remaining second half material, the chamfering blades of promptly cutting the ladder sword of straightway and cutting chamfering section is in a plane, so two sections cutting edge cutting edges cut simultaneously in the actual cut process, cutting force radial component maximum influences stable cutting, precision and surface quality.
Summary of the invention
It is steady that technical problem to be solved by this invention provides a kind of working angles that makes, improves the ladder milling cutter of crudy.
The objective of the invention is to be achieved through the following technical solutions:
One species stage milling cutter comprises handle of a knife and cutter hub, and this cutter hub is provided with ladder sword and chamfering blades, offers spiral grooves and skewed slot on the described cutter hub, and this spiral grooves and this skewed slot intersect; Described ladder sword is the helical edges on this spiral grooves cell wall, and described chamfering blades is the straight line sword on this skewed slot cell wall.
Above-mentioned ladder milling cutter forms helical cutting edge respectively as the ladder sword of this ladder milling cutter, the straight line edge chamfering blades as this ladder milling cutter owing to offered spiral grooves and skewed slot on cutter hub; The straight sword of helical edges, the incision of cutting edge is gradual change with cutting out, and has guaranteed the stationarity of cutting, has increased cutting edge real work anterior angle, and then has effectively improved workpiece machining accuracy and surface quality; Spiral grooves and this skewed slot are the smoothnesses that intersects chip removal in the time of guaranteeing cutting, and in sum, this ladder milling cutter has not only possessed the advantage of skew cutting cutter but also solved the shape problem of chamfering place cutting edge.

The specific embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments.
The present invention includes handle of a knife and cutter hub 200, as shown in Figure 4, this cutter hub 200 is provided with ladder sword 211 and chamfering blades 221, offers spiral grooves 210 and skewed slot 220 on the described cutter hub 200, spiral grooves 210 and skewed slot 220 intersect, and described ladder sword 211 is the helical edges on these spiral grooves 210 cell walls; Described chamfering blades 221 is the straight line swords on these skewed slot 220 cell walls.
Present embodiment is intended to by offer spiral grooves 210 and skewed slot 220 on cutter hub 200, uses the ladder sword 211 of formation helical cutting edge on cutter hub 200 and the chamfering blades 221 of straight line edge.Helical edges 211 straight swords, had cutting edge inclination, cutting edge inclination makes cutting edge cutting force resolve into the synthetic of radial load and axial force by radial load completely, the incision of cutting edge is gradual change with cutting out, overcome the ropy deficiency of vibration, precision and surface to be machined that plane sword tooth shape milling cutter causes greatly because of radial cutting force in working angles, guaranteed the stationarity of cutting, also increased cutting edge real work anterior angle, and then effectively improved workpiece machining accuracy and surface quality.Spiral grooves 210 and skewed slot 220 intersects, and promptly ladder sword 211 and chamfering blades 221 are positioned at the same side, and the same side design is a chip removal smoothness in order to guarantee to cut.All the above, institute's invention cutter has not only possessed the advantage of skew cutting cutter but also has solved the shape problem of chamfering place cutting edge, thereby makes working angles steady, product to be processed element precision and surface quality are guaranteed.
During making, stairs of knives sword 211 cutting edges are formed by the wall scroll spiral grooves 210 that wheel grinding processes, this process has guaranteed that stairs of knives sword 211 cutting edges are helical edges, promptly as the helical angle ω that has formed ladder sword 211 among Fig. 7, the anterior angle γ (see figure 6) of ladder sword 211.But because the external diameter section of having of ladder sword 211 cutting edges and chamfering blades 221 cutting edges is poor, so only a helicla flute 210 can cause chamfering blades 221 cutting edge places not straight because of external diameter changes, thereby influence processing is by the product size precision.For solving this contradiction, 221 places grind skewed slot 220 in chamfering blades, have promptly guaranteed chamfering blades 221 oblique angle θ and the long L1 of ladder sword 211 swords in Fig. 7, and this process has guaranteed that cutter chamfering blades 221 is the straight line sword.After the oblique angle θ of the anterior angle γ of the helical angle ω of ladder sword 211, ladder sword 211, chamfering blades 221 and the long L1 of ladder sword 211 swords finished, primary clearance α 1, front clearance α 2 by grinding ladder sword 211 finished ladder sword 211 external diameters
And the control of the long L1 of ladder sword 211 swords, realized the making of ladder sword 211 cutting edges in the product processing; By grinding chamfering blades 221 relief angle α 3, realized the making of chamfering blades 221 cutting edges in the product processing.
As preferably, below provide each parameter area of ladder sword 211 (helical edges) and chamfering blades 221 (straight line sword):
The helical angle ω scope of ladder sword 211 is: 3 °～15 °.
The anterior angle γ scope of ladder sword 211 is: 5 °～20 °.
Primary clearance α 1 scope of ladder sword 211 is: 8 °～15 °.
Attached angle α 2 scopes of ladder sword 211 are: 16 °～30 °.
The oblique angle θ scope of chamfering blades 221 is: 30 °～60 °.
Relief angle α 3 scopes of chamfering blades 221 are: 8 °～15 °.
Below only expressed several embodiment of the present invention, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
