Abstract
The utility model discloses a T-type channeling cutter, comprising an edge part, a cutter neck and a shank. The characteristics are that the edge part is provided with end face teeth, the number of the teeth at the edge part is few, the angle of a sludge slot is big, and a chip flute is big and deep. So the single tooth has large strength, and the sludge is expedite. The utility model is used to process the carbon steel and the stainless steel workpieces and has the advantages of saving time and high work efficiency.
Description
The utility model relates to the T-slot milling cutter that a kind of machining is used.
Known T-slot milling cutter (State Standard of the People's Republic of China GB1126-73) and to scabble the common problem that exists of type staight shank T-slot milling cutter (State Standard of the People's Republic of China GB6124-85) be the blade number of teeth many (8～10 teeth), monodentate intensity is little; Flute angle little (all less than 10 degree), it is not smooth to go out bits; Land diagonal cross and do not have end face tooth, processing time consuming.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of T-slot milling cutter that bits are smooth, monodentate intensity is big and work efficiency is high that goes out is provided.
The technical solution of the utility model is: form a kind of T-slot milling cutter by blade, cutter neck and handle of a knife, it is characterized in that having the end face tooth at the blade of milling cutter, the flute angle is greater than 10 degree (as 20 degree) and the T-slot milling cutter of the more known same specification of the blade number of teeth few (as few 1/3rd), blade is a right-hand screw shape, fillet is about R1.5 at the bottom of the teeth groove, and groove angle is about 65 °, and the end face tooth also is a right-hand screw shape, groove angle is about 25 °, and the bottom land fillet is about R2.
The utility model has following advantage compared to existing technology: chip pocket is big and dark, and monodentate intensity height cut briskly, and it is smooth to go out bits, can improve work efficiency 1/3rd in order to the T-slot of processing stainless steel and charcoal steel workpiece is about.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structure chart of known T-slot milling cutter.
Fig. 2 is a T-slot milling cutter detail of construction of the present utility model.
Now embodiment of the present utility model is described further in conjunction with Fig. 2:
T-slot milling cutter shown in Figure 2 is made up of blade 1, cutter neck 2 and handle of a knife 3 three parts.Its flute angle is greater than 10 degree (as 20 degree), and the blade number of teeth is 6 teeth, and the oblique unanimity of land and the back of tooth are circular arc, and blade has the end face tooth and processes with blade integral body.The teeth groove tool cutting edge angle be 1 ° 30 ', anterior angle 10
°+2 °, 14 ° of relief angles.The Clearance angle of end face tooth is 25 °, and anterior angle and relief angle are all 10 °.The material of blade 1 is a W18Cr4V tool steel, and the material of handle of a knife 3 is a charcoal steel in No. 45, and its heat treatment hardness is respectively HRC63～66 and HRC35～45, and blade 1 and handle of a knife 3 are sentenced butt welding at cutter neck 2 and connected.
Claims (2)
1, a kind of T-slot milling cutter is made up of blade 1, cutter neck 2 and handle of a knife 3, it is characterized in that having on the blade 1 the end face tooth, and the flute angle is greater than 10 degree, and the more known T-slot milling cutter of the blade number of teeth is few, and blade 1 and end tooth are all right-hand screw shape.
2, T-slot milling cutter as claimed in claim 1, it is characterized in that the teeth groove of blade 1 at the bottom of fillet be about R1.5, groove angle is about 65 °.
