Description

The dedicated tool in hole is intersected in a kind of processing with flash removed
Technical field
The utility model relates to cutting tool field, particularly the shaping ball-end mill of one, specifically refers to that the dedicated tool in hole is intersected in a kind of processing with flash removed.
Background technology
In the process of metal product, often need to use CNC (Digit Control Machine Tool) to process.After adopting CNC to process two crossing holes, intersect hole bottom outlet and have water caltrop, the position between holes can be jagged.At present, still adopt the method for artificial removal's burr in actual production, namely operative employee removes crossing hole bur with file, and not only deburring is difficult in handwork, production efficiency is low, and easily easily there is again the situation of leaking flash removed in scuffing product, so that affect product quality.
Along with the development of Chinese process technology level, overseas enterprise progressively moves on to China mach product manufacturing center of gravity, and the demand of product constantly increases, processing mode in the past, and working (machining) efficiency does not reach the requirement of output far away.Original cutter is also difficult to complete processing tasks smoothly efficiently.Therefore, need to design and a kind ofly process crossing hole and there is the cutter of flash removed function, thus reduce aft-loaded airfoil operation, enhance productivity.
Utility model content
The purpose of this utility model is that the shortcoming overcoming above-mentioned prior art is with not enough, provides a kind of and can process the cutter that crossing hole site burr can be removed again in crossing hole, thus solve artificial deburring difficulty, easily scuffing product and leak the problems such as flash removed.
The purpose of this utility model intersects the special realization in hole by the processing as follows with flash removed.
The dedicated tool in hole is intersected in a kind of processing with flash removed, it is characterized in that: it comprises the cutter body that centrally axle rotates, described cutter body leading portion is provided with bulb cutting portion, and cutter body stage casing is provided with helicla flute chip removal portion, and the back segment of cutter body is provided with shank section; Described bulb cutting portion is provided with two bulb cutting edges, the bulb cutting portion end between bulb cutting edge is provided with two and is conducive to cutting the helical flute of discharging.
Described bulb cutting portion 1 diameter is greater than helicla flute chip removal portion 2 diameter, and helicla flute chip removal portion 2 diameter is greater than the diameter of shank section 3.
The utility model compared with prior art has following outstanding advantage:
1, the utility model devises and a kind ofly can make the round and smooth dedicated tool can removing again crossing hole site burr in intersection area, processed crossing hole, once realizes processing and flash removed function, improves working (machining) efficiency, reduces product and scratches and leakage flash removed risk;
2, the utility model structure is simple, easy to operate, and can be widely used in, in the processing in crossing hole, has actual application value, easily apply in industry.
Accompanying drawing explanation
Fig. 1 is the dedicated tool structural representation being with the processing of flash removed to intersect hole;
In figure: bulb cutting portion 1, helicla flute chip removal portion 2, shank section 3.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the dedicated tool in hole is intersected in a kind of processing with flash removed, comprise the cutter body that centrally axle rotates, its feature is that described cutter body leading portion is provided with bulb cutting portion 1, cutter body stage casing is provided with helicla flute chip removal portion 2, the back segment of cutter body is provided with shank section 3, described bulb cutting portion is provided with two bulb cutting edges, bulb cutting portion 1 end between bulb cutting edge is provided with two helical flutes, and the design of helical flute is more conducive to the discharge of cutting.In order to avoid the shank section 3 of ball-end mill is interfered with workpiece hole, described bulb cutting portion 1 diameter is greater than helicla flute chip removal portion 2 diameter, and helicla flute chip removal portion 2 diameter is greater than the diameter of shank section 3.
Ball-end mill is arranged on common handle of a knife by the shank section 3 of cutter body back segment, then is arranged on numerically controlled lathe by common handle of a knife.When program brings into operation, drive ball-end mill action by spindle of numerical control lathe action; Subsequently, ball-end mill vertically enters in rough machined hole, and because rough machined bore dia is larger than ball-end mill bulb cutting portion 1 diameter, ball-end mill can not carry out secondary operations to hole wall; When the bulb cutting portion 1 of ball-end mill arrives the bottom of intersecting hole, namely ball-end mill rotates, and starts again with certain radius circular motion, therefore, the bulb cutting portion 1 of ball-end mill is processed and is intersected hole bottom outlet, makes bottom outlet become round and smooth and removes the burr intersected in hole.When after process finishing, ball-end mill axle center returns along workpiece hole axle center, avoids secondary operations.
