Abstract
The utility model discloses a spiral slot forming end milling cutter, which comprises a handle portion and a blade portion. A spiral angle of the blade portion ranges from 25 degrees to 35 degrees, and a front angle of the blade portion is larger than zero degree. After adopting the structure, the front angle of the cutter is enlarged, thereby resistance and cutting scrap deformation in cutting are reduced, and a blade opening is sharpened. Additionally, since a spiral slot more effectively favors discharge of iron scraps than a straight slot, scrap discharging speed is accelerated, and large feeding processing can be adopted, thereby the spiral slot forming end milling cutter improves mechanical processing efficiency.
Description
Technical field
The utility model relates to a kind of moulding slotting cutter, especially relates to a kind of spiral flute type moulding slotting cutter.
Background technology
The moulding slotting cutter is mainly used in the processing of complex-shaped workpieces as an important component part in the machining usefulness cutter, and the copying of forming surface.Along with popularizing of Digit Control Machine Tool, Computerized Numerical Control processing technology increasingly mature, the user is to having proposed high requirement at delivery date of the crudy of product, process reliability, working (machining) efficiency, cutter etc.Tradition moulding slotting cutter mainly is the straight trough type, is processing on the cutter and tool grinding machine or on optical contour grinder.To straight trough type moulding slotting cutter shown in Figure 2, its shortcoming is: 1, the cutting edge of cutter is not sharp, chip removal has some setbacks, chip deformation is big when cutting, resistance to cutting is big as Fig. 1; 2, tool wear is fast, can not cut by roughing feed, and cutter life is low, machining efficient is low.
The utility model content
The purpose of this utility model provides a kind of spiral flute type moulding slotting cutter by numerically control grinder processing, has overcome the above-mentioned shortcoming of traditional straight trough type moulding slotting cutter, can effectively increase work efficiency, and reduces production costs.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of spiral flute type moulding slotting cutter is made up of shank and blade.
The helical angle of blade is between 25 ° to 35 °, and anterior angle is greater than 0 °.
The beneficial effects of the utility model are:
After adopting said structure, the anterior angle of cutter increases, thereby drag and chip deformation when having reduced cutting make cutting edge become sharp.Because helicla flute is more conducive to the discharge of iron filings than straight trough, chip removal speed accelerates, and can adopt roughing feed processing, thereby improve machining efficient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of known straight trough type moulding slotting cutter;
Fig. 2 is the A-A section partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of spiral flute type moulding slotting cutter of the present utility model;
Fig. 4 is the B-B section partial enlarged drawing of Fig. 3;
Among the figure: 1, blade; 2, shank.
The specific embodiment
A kind of spiral flute type moulding slotting cutter is made up of shank (2) and blade (1).
The helical angle of blade (β) is between 25 ° to 35 °, and anterior angle (r) is greater than 0 °.
This utility model is to utilize numerical control five-axle interlock grinding machine, independently writes the moulding knives routine and processes automatically.High and suitable batch process the in batches of contour accuracy; Because the grooved of spiral flute type moulding slotting cutter described in the utility model is a screw type, can accurately control its grinding track by special processing equipment, compare traditional manual operations, improved the stability of machining accuracy and batch process, because helical angle and anterior angle increase, make cutting edge become sharp, cutting edge becomes gradual some contact with contacting by original line contact of workpiece, drag and chip deformation when having reduced cutting, the cutter friction is little, can adopt roughing feed processing, helicla flute is more conducive to the discharge of iron filings than straight trough simultaneously, thereby has improved the service life of machining efficient and cutter.
Claims (1)
