Abstract

The utility model discloses a round-nose vertical milling cutter for machining, which solves the problems that an existing vertical milling cutter is unsmooth to discharge scraps, and the point of the milling cutter is easy to tipping. The round-nose vertical milling cutter has the advantages of easy scrap discharge and high strength of a cutter edge through arranging a plurality of cutter teeth (2) and a scrap discharge groove (3) on a cutter body in a helix angle of 35 degrees.

Description

The round nose slotting cutter

Affiliated technical field the utility model relates to a kind of metal cutting tool, especially relates to a kind of round nose slotting cutter of being made up of handle of a knife, cutter hub, cutter tooth and chip area.

Background technology is present, a kind of like this slotting cutter is disclosed on the market, its design feature is: by handle of a knife, cutter hub, cutter tooth and chip area are formed, the cutter hub of handle of a knife one end is provided with several cutters tooth and chip area, chip area is arranged between the two adjacent cutters tooth, cutter tooth and chip area shape in the shape of a spiral are arranged on the cutter hub, its several cutters tooth are arranged on the cutter hub with chip area with identical helical angle symmetrically, because the cutter tooth helical angle is 25 °-30 ° and easily causes chip removal not smooth, again because angle, cutter tooth front and back is excessive, when impulsive force is big, easily produce point of a knife tipping phenomenon, influence milling cutter service life.

The summary of the invention the purpose of this utility model provides the round nose slotting cutter that a kind of chip removal is easy, be difficult for the generation tipping, enhance productivity.

For achieving the above object, the utility model round nose slotting cutter, form by handle of a knife, cutter hub, cutter tooth and chip area, the cutter hub of handle of a knife one end is provided with several cutters tooth and chip area, chip area is arranged between the two adjacent cutters tooth, cutter tooth and chip area shape in the shape of a spiral are arranged on the cutter hub, and several cutters tooth and chip area are 35 ° of helical angles and are arranged on the cutter hub.

The back of tooth of cutter tooth is made up of the major first flank and the second back knife face, and major first flank is arranged between the blade and the second back knife face of cutter tooth.

Between the circumference sword of milling cutter and end face, arc transition is set.

After adopting this structure, owing on cutter hub, be provided with the cutter tooth that is 35 ° of helical angles, make chip removal more freely suitable, again owing to the back of tooth of cutter tooth is made up of the major first flank and the second back knife face, major first flank is arranged between the blade and the second back knife face of cutter tooth, thereby has increased the toughness and the intensity of blade, simultaneously, between the circumference sword of milling cutter and end face, arc transition is set again, has avoided milling cutter when machining, to cause the tipping phenomenon owing to point of a knife is too sharp.

The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.

Fig. 1 is the main cross-sectional schematic of the utility model round nose slotting cutter.

Fig. 2 be Figure 1A-A to cross-sectional schematic.

Among the figure: 1. cutter hub 2. cutters tooth 3. chip areas 4. handle of a knifes.

The slotting cutter of the utility model round nose shown in the specific embodiment accompanying drawing, form by handle of a knife 4, cutter hub 1, cutter tooth 2 and chip area 3, the cutter hub 1 of handle of a knife 4 one ends is provided with several cutters tooth 2 and chip area 3, chip area 3 is arranged between the two adjacent cutters tooth 2, cutter tooth 2 and chip area 3 shape in the shape of a spiral are arranged on the cutter hub 1, and several cutters tooth 2 and chip area 3 are 35 ° of helical angles and are arranged on the cutter hub 1; The back of tooth of cutter tooth 2 is made up of the major first flank and the second back knife face, and major first flank is arranged between the blade and the second back knife face of cutter tooth 2; Between the circumference sword of milling cutter and end face, arc transition is set.
