Abstract
The utility model relates to an end mill, in particular relates to an end mill for milling on hard materials. An end mill is composed of a cutter part, a neck part and a handle part, wherein the cutter part is arranged in the front of the end mill, the neck part is arranged in the middle of the end mill, and the handle part is arranged on the rear side of the end mill; and the cutter part is provided with four sets of regularly-arranged cemented carbide cutter teeth, the cemented carbide cutter teeth are obliquely arranged on the side face of the cutter part, and an inclined angle between each cemented carbide cutter tooth and a central shaft of the cutter part is 3 degrees, and the front end of each set of cemented carbide cutter teeth is protruded from the front end face of the cutter part. The end mill disclosed by the utility model is used for carrying out milling processing on hard materials, and has the main advantages that the end moll is high in cutter-tooth hardness, suitable for high-strength milling, strong in cutting capacity and good in effect.
Description
Technical field
The utility model relates to a kind of slotting cutter, particularly relates to a kind of slotting cutter that is used in milling on the hard material.
Background technology
Slotting cutter is of a great variety at present, is main with high manganese steel material mainly.These slotting cutters all are that the various workpiece of reply are popularized use; Though it is low to produce cost in batches; But the milling on hard material of this type slotting cutter exposes a large amount of defectives: the cutter tooth hardness and the intensity that at first are this type slotting cutter do not reach requirement, as easy as rolling off a log wearing and tearing or breaking; The cutter tooth of secondly existing slotting cutter is provided with the milling requirement that all can't satisfy on the hard material in the number of teeth and angle, a little less than the cutting power, and weak effect.
Summary of the invention
The goal of the invention of the utility model provides a kind of Milling Process on the hard material that is used in, and cutter tooth hardness is high, is suitable for the high strength milling, and cutting power is strong, effective slotting cutter.
The utility model the technical scheme that will adopt be:
A kind of slotting cutter; Link to each other by the shank of the cutter portion of its front side, middle neck and rear side and to constitute; Cutter portion is provided with 4 groups of regularly arranged carbide alloy cutters tooth; The oblique side that is located at cutter portion of carbide alloy cutter tooth, the angle of the central shaft of itself and cutter portion is 3 °, the front end of every group of carbide alloy cutter tooth stretches out cutter portion front end face.
As preferably, the rear end of shank is provided with screwed hole; Screwed hole is used for equipped slotting cutter, makes this slotting cutter high speed rotating working stability, not lifts.
As preferably, the said front end face that stretches out the carbide alloy cutter tooth of cutter end surface is the plane.
Adopt a kind of slotting cutter of technique scheme design, select the processing of carbide alloy cutter tooth reply hard material for use, hardness is strong, not easy to wear or breaking; Since the carbide alloy cutter tooth is oblique be located at cutter portion the side and with the angle of the central shaft of cutter portion be 3 °, the quantity of carbide alloy cutter tooth is 4 groups, when cooperating 3 ° of slanted angles can keep cutting power strong, makes the slotting cutter stable working again, cutting effect is good.
Description of drawings
Fig. 1: the structural representation of the utility model embodiment.
The specific embodiment
Be to combine the technical scheme of 1 pair of the utility model of accompanying drawing to describe in further detail below.
A kind of slotting cutter as shown in Figure 1; Link to each other by the shank 3 of the cutter portion 1 of its front side, middle neck 2 and rear side and to constitute; Cutter portion 1 is provided with 4 groups of regularly arranged carbide alloy cutters tooth 11; 4 groups of carbide alloy cutters tooth 11 are 4 thicker carbide alloy vertical bars; Carbide alloy cutter tooth 11 is oblique be located at cutter portion 1 the side and with the angle theta of the central shaft of cutter portion 1 be 3 °, the small angle inclination here be the quantity at analysis-by-synthesis carbide alloy cutter tooth 11 be 4 groups with the workpiece hard material on the going out of required cutting hardness.When angle theta was excessive, cutting hardness weakened, and was inappropriate for the roughing of this hard material workpiece; And angle theta is 0 o'clock, and cutting hardness is excessive, and tool setting height speed stability of rotation degree requires high, easily lifts.During use, 3 ° have the effect of highlighting at this slotting cutter in side or the groove of processing hard material, when both having kept cutting power strong, and working stability again, lifts not, cutting effect is good.The front end of every group of carbide alloy cutter tooth 11 stretches out cutter portion front end face, and the front end face that stretches out the carbide alloy cutter tooth 11 of cutter end surface is the plane, and therefore the slotting cutter end face need not establish complicated cutting edge at the slotting cutter end face generally not in order to the high strength milling.The rear end of shank 3 is provided with screwed hole, and screwed hole is used for equipped slotting cutter, makes slotting cutter high speed rotating reposefully, the high strength processing of reply hard material workpiece.
Claims (3)
1. slotting cutter; It is characterized in that shank (3) by the cutter portion (1) of its front side, middle neck (2) and the rear side formation that links to each other; Cutter portion (1) is provided with 4 groups of regularly arranged carbide alloy cutters tooth (11); The oblique side that is located at cutter portion of carbide alloy cutter tooth (11), the angle of the central shaft of itself and cutter portion (1) is 3 °, the front end of every group of carbide alloy cutter tooth stretches out cutter portion front end face.
2. a kind of slotting cutter according to claim 1 is characterized in that the rear end of shank (3) is provided with screwed hole.
3. a kind of slotting cutter according to claim 1 is characterized in that the said front end face that stretches out the carbide alloy cutter tooth (11) of cutter end surface is the plane.
