Abstract
A kind of wiring board milling cutter, comprise cylindrical cutter body, the rear portion of cutter hub is set to shank section, the front portion of cutter hub is set to cutting portion, the cylindrical cutter body of cutting portion front portion is evenly provided with seven spiral cutting edges, cutter hub forward end is provided with the anterior angle of seven profiles of tooth, the inner axle center towards cutter hub of anterior angle, anterior angle outer end is connected with cutting edge, has the chip area concaved between anterior angle; Cutting edge and chip area are in turning clockwise, and cutting edge is provided with cone angle.The utility model adds the hardness of milling cutter, reduces and weares and teares, and promotes the precision of gong board size, is provided with multiple chip area and effectively improves chip removal effect, while increase ensures chip removal effect, arrange cone angle on the cutting edge, effective increase cutting surface glossy effect; Also there is long service life simultaneously, after the reduction knife face degree of wear, its gong plate is increased entire life greatly; Verified by Experimental Comparison, while ensuring the quality of products, gong plate cost-per-meter reduces by 45% on the contrary, effectively can reduce production cost, increase work efficiency.
Description
Technical field
The utility model relates to wiring board and manufactures field, particularly relates to a kind of wiring board milling cutter.
Background technology
Along with the broad development of printed circuit board (PCB) production technology and application, various high low side electronic equipment all needs a large amount of printed circuit board (PCB)s, for meeting market production capacity and high precision demand, enterprise constantly increases its equipment, scientific research and personnel and drops into, and increases the competitiveness of enterprise.The printed circuit board (PCB) major part used in electric product in the past has plastics or glass material to make, but, constantly promote along with manufacturing technology and develop, the requirement of the printed circuit board (PCB) that electric product uses is improved gradually, requires more and more higher to the intensity of printed circuit board (PCB), hardness, withstand voltage and corrosion resistance etc.Also can increase accordingly the quality requirement of the milling cutter that printed circuit board (PCB) is processed while the requirements of printed circuit board (PCB) is increased.
At present, the groove of conventional milling cutter is less, and add man-hour requirement Reusability milling cutter and process, cause machining accuracy low, need reprocessabilty, cutter wear degree is high, needs often to change milling cutter, reduces production efficiency, lose time and labour; The cutting portion of milling cutter adds man-hour to printed circuit board (PCB) simultaneously, easily occurs strangling cutter phenomenon, increases the fraction defective of product, and material is produced in waste, increases cost, affects production efficiency.
Utility model content
In view of this, the utility model provides a kind of long service life, and processing section is smooth, the wiring board milling cutter that dust discharge is effective.
The design that the utility model is taked is: a kind of wiring board milling cutter, comprise cylindrical cutter body, the rear portion of cutter hub is set to shank section, the front portion of cutter hub is set to cutting portion, the cylindrical cutter body of described cutting portion front portion is evenly provided with seven spiral cutting edges, cutter hub forward end is provided with the anterior angle of seven profiles of tooth, the inner axle center towards cutter hub of anterior angle, anterior angle outer end is connected with cutting edge, has the chip area concaved between anterior angle; Described cutting edge and chip area are in turning clockwise, and cutting edge is provided with cone angle.
Wherein, described cone angle is in turning clockwise, and the anglec of rotation is 28 degree.
Wherein, the external diameter of described shank section is greater than the external diameter of cutting portion.
Wherein, milling cutter adopts wolfram steel material to make.
Compared with prior art, the utility model adds the hardness of milling cutter, reduce wearing and tearing, promote the precision of gong board size, be provided with multiple chip area and can effectively improve chip removal effect, while increase ensures chip removal effect, cone angle is set on the cutting edge, can effectively adds cutting surface glossy effect; Also there is long service life simultaneously, after the reduction knife face degree of wear, its gong plate is increased entire life greatly.Verified by Experimental Comparison, while ensuring the quality of products, gong plate cost-per-meter reduces by 45% on the contrary, effectively can reduce production cost, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is upward view of the present utility model.
Fig. 3 is the enlarged drawing of the cutting edge in the utility model.
Detailed description of the invention
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further elaborated.
Fig. 1 to Fig. 3 is the wiring board milling cutter construction schematic diagram of the utility model embodiment.As shown in Fig. 1 to Fig. 3, a kind of wiring board milling cutter comprises cylindrical cutter body 1, and the rear portion of cutter hub 1 is set to shank section 11, the front portion of cutter hub is set to cutting portion 12, handle of a knife, 11 and cutting portion 12 be structure as a whole, such design organization is simple, reduce manufacturing cost, be convenient to promote.Rightly better wiring board to be processed, raise the efficiency and machining accuracy, the cylindrical cutter body 1 of cutting portion 12 front portion is evenly provided with seven spiral cutting edges 121, there is the anterior angle 122 of seven profiles of tooth cutter hub 1 front end, anterior angle 122 the inner is towards the axle center of cutter hub 1, and anterior angle 122 outer end is connected with cutting edge 121.Can discharge fast in time to make to add the bits foam that man-hour, milling cutter produced, between anterior angle, having the chip area 123 concaved, the bits foam produced is removed by processing limit, limit, effectively improves operating efficiency.Described cutting edge 121 and chip area 123 are in turning clockwise.In order to add cutting surface glossy effect, be provided with cone angle 1211 on the cutting edge.This cone angle 1211 is in turning clockwise, and the anglec of rotation is 28 degree.
In order to milling cutter is fixed in installation just, the external diameter of described shank section 11 is greater than the external diameter of cutting portion 12.
In order to improve the abrasion resistance of milling cutter, increase the service life of milling cutter, milling cutter adopts wolfram steel material to make.
It is more than the utility model preferably implementation; it should be noted that; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change and are out of shape the protection domain that all should belong to the claim appended by the utility model.
