Abstract
The utility model discloses a form-relieved grinding wheel of a thread milling cutter, which comprises a cylindrical base. An annular groove is arranged on one side of the base, the cross section of the annular groove is V-shaped, the bottom of the annular groove is circular, and the included angle alpha of the annular groove ranges from 29.45 degrees to 30.55 degrees. The form-relieved grinding wheel is simple in structure and reasonable in design, can be used for grinding tooth form of the thread milling cutter with a helical chip flute, can not only guarantee consistency of internal grinding capacity and external grinding capacity of the tooth form of the milling cutter but have higher precision of the tooth form of the milling cutter, and accordingly is quite practical.
Description
Technical field
The utility model relates to the grinding tool of process tool cutting edge, particularly relates to a kind of screw cutter teeth emery wheel.
Background technology
At present; The teeth grinding wheel section shape structure of known screw cutter is according to being added what the stagger of emery wheel on lathe obtained by the thread form shape of relief grinding; When such teeth emery wheel has the screw cutter thread form of straight trough at relief grinding, can obtain higher processing precision.But for the ease of chip removal; Many screw cutters need have helical flute, like the teeth emery wheel of still constructing with common section shape its thread form are carried out relief grinding processing, and helicla flute can make the milling cutter cutter tooth outside contact earlier with emery wheel; Contact behind inboard and the emery wheel; Cause the inside and outside side stock removal of milling cutter tooth form different, cause the profile of tooth deviation of milling cutter, and then influence screw processing quality.
The utility model content
The technical problem that the utility model will solve provides a kind of screw cutter teeth emery wheel; When the screw cutter with helical flute being carried out the thread form grinding; The inside and outside grinding amount that not only can guarantee milling cutter tooth form is identical, and can obtain higher milling cutter tooth form precision.
For solving the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of screw cutter teeth emery wheel, comprise matrix, and said matrix is cylindrical; The side of said matrix has an annular groove; The cross section of this annular groove is V-shaped, and the bottom of annular groove is a circular arc, and the angle that this annular groove forms is 29.45 °-30.55 °.
Further technical scheme, the outer surface of said matrix is coated with abrasive material.
Technical scheme further, said abrasive material is any one in metal-bonded diamond layer, metal binder cubic boron nitride layer, resinoid bond diamond layer or the resin cement cubic boron nitride layer.
Technical scheme further, said matrix is steel or aluminium.
Compared with prior art; The beneficial effect of the utility model is: simple in structure, reasonable in design; When the screw cutter with helical flute being carried out the thread form grinding; The inside and outside grinding amount that not only can guarantee milling cutter tooth form is identical, and can obtain higher milling cutter tooth form precision, and is very practical.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model screw cutter teeth emery wheel;
The view that Fig. 2 grinds for the utility model double thread milling cutter.
Among the figure: 1-matrix, 2-annular groove, 3-screw cutter.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1, a kind of screw cutter teeth emery wheel comprises matrix 1, and said matrix 1 is cylindrical, and matrix 1 is steel or aluminium.The side of said matrix 1 has an annular groove 2, and the cross section of this annular groove 2 is V-shaped, and the bottom of annular groove 2 is a circular arc, and the angle that this annular groove 2 forms is 29.45 °-30.55 °, in the present embodiment is 30 °.The outer surface of said matrix 1 is coated with abrasive material.Said abrasive material is any one in metal-bonded diamond layer, metal binder cubic boron nitride layer, resinoid bond diamond layer or the resin cement cubic boron nitride layer.
As shown in Figure 2, the view when Fig. 2 grinds for the utility model double thread milling cutter 3.As can be seen from Figure 2, when the screw cutter 3 with helical flute being carried out the thread form grinding, the inside of annular groove 2 contacts with the cutter tooth of screw cutter.The inside and outside grinding amount that not only can guarantee milling cutter tooth form like this is identical, and can obtain higher milling cutter tooth form precision.
Need to prove at last; The above is merely the preferred embodiment of the utility model; Rather than, anyly be equal to replacement or corresponding improvement to what the utility model technical characterictic did to the qualification of the utility model technical scheme, still within the protection domain of the utility model.
