Abstract
The invention discloses a method for processing a super short groove printed board. The method is characterized by comprising the following steps of: (1) during edition of a printed board pattern file, rotating a super short groove pattern of the printed board pattern file, wherein the rotating amount is 1.0-2.0mil; (2) during drilling operation on the super short groove, pre-drilling a central hole of which the diameter is the same as the groove width at the central position of the super short groove; and (3) performing super short groove drilling operation by using a special type drilling tool: drilling a start hole, a tail end hole, a middle hole I and a middle hole II in sequence to form the super short groove finally. According to the method, the super short groove pattern is rotated during edition of the printed board pattern file, and a corresponding drilling program is output for directly processing, so that manual adjustment in a drilling procedure is not required, the stability of product quality is enhanced greatly, and the production efficiency is increased.
Description
Technical field
The present invention relates to a kind of processing method of ultrashort groove printed board, specifically, relating to a kind of flute length is the drilling method of tool diameter 1.1-1.5 ultrashort groove printed board doubly.
Background technology
Along with modern electronic product day by day to miniaturization, high integrated, high performance trend development, the aperture of boring is more and more less, borehole accuracy is more and more higher, ultrashort slotted eye and long slotted eye also get more and more, quality requirements is also more and more higher, the particularly making of ultrashort groove, its quality directly have influence on installation and the use of client's product, and the technical barrier that industry all is faced with ultrashort groove distortion is made at present printed board.When making flute length less than twice tool diameter even shorter ultrashort groove, because flute length is less, so that ultrashort groove two ends in boring procedure are subjected to force direction inconsistent and the problems such as distortion, the hole is large, the hole is little very easily occur, thereby affect quality; And because drill bit will bear very large radial load and the double action of moment of torsion in the going down process of drill flute, make that cutter is easier to fracture, particularly when processing ultrashort groove below 1.5 times, it is more outstanding that problem just seems, flute length is shorter, and the radial load that cutter bears and axial moment are just larger.When in machine drilling, running into the slotted eye of ultrashort groove or length, not only have a strong impact on production efficiency and quality, and also thereupon raising of production cost, be to suffer untold misery.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of processing method of ultrashort groove printed board.Described method is selected special drilling tool, ultrashort groove place figure is rotated when the Document Editing, and adjusts drilling parameter, make flute length be tool diameter 1.1-1.5 doubly ultrashort groove is after boring, dimension control is at ± 4mil, namely ± 0.1mm in.The technological means that the present invention adopts is as follows:
A kind of processing method of ultrashort groove printed board is characterized in that may further comprise the steps:
1) when printed board figure file is edited, the ultrashort groove figure of printed board figure file is rotated, its rotation amount is 1.0mil-2.0mil;
2) ultrashort groove is when carrying out bore operation, the measure-alike centre bore of diameter of heart position preboring and groove width therein, and technical parameter is as follows:
| The technical parameter item | Control criterion |
| Rotating speed S | 60-100krpm |
| Feeding F | 100-180ipm |
3) select the specific type drilling tool, namely the cutter of 160 ° of drill point angles, helical angle 20-30 °, the long 4mm of sword bores ultrashort groove operation, and technical parameter is as follows:
| The technical parameter item | Control criterion |
| Rotating speed S | 30-50krpm |
| Feeding F | 50-90ipm |
The described process of selecting the specific type drilling tool to bore ultrashort groove operation is as follows: the order according to starter hole, end aperture, interstitial hole I, interstitial hole II is holed, and finally forms ultrashort groove.
Compare with prior art, advantage of the present invention is apparent, and is specific as follows:
1, ultrashort groove figure is rotated when printed board figure file is edited, and exports corresponding drilling program and directly process, need to artificially not adjust at drilling operating, improved greatly stability and the production efficiency of product quality.
2, flute length be tool diameter 1.1-1.5 doubly ultrashort groove is after boring, flute profile control is good, without distortion, become large or the problem that diminishes, dimension control is at ± 4mil, namely ± 0.1mm in.

Among the figure: 1, ultrashort groove, 1a, ultrashort groove arc center, 1-1, ultrashort groove rotating graphs, 1-1a, ultrashort groove rotating graphs arc center, 1-2, ultrashort groove center, 2, centre bore, 3, starter hole, 4, end aperture, 5, interstitial hole I, 6, interstitial hole II
The specific embodiment
The processing method of a kind of ultrashort groove printed board as depicted in figs. 1 and 2 may further comprise the steps:
1) when using printed board figure Document Editing special-purpose software GENESIS system that printed board figure file is edited (the present invention describes as example with the GENESIS system), ultrashort groove figure to printed board figure file is rotated, and drilling program corresponding to output;
2) use conventional cutter that prebored hole is carried out in the center of ultrashort groove, technical parameter is as follows:
| The technical parameter item | Control criterion |
| Rotating speed S | 60-100krpm |
| Feeding F | 100-180ipm |
3) select the specific type drilling tool to bore ultrashort groove operation, technical parameter is as follows:
| The technical parameter item | Control criterion |
| Rotating speed S | 30-50krpm |
| Feeding F | 50-90ipm |
Described ultrashort groove figure rotates when printed board figure file is edited in the direction of the clock, and its rotation amount is 1.0-2.0mil, decides according to the thickness of slab of printed board and the flute length of ultrashort groove.Described ultrashort groove when carrying out bore operation, the measure-alike centre bore of diameter of heart position preboring and groove width therein.160 ° of the drill point angles of described cutter, helical angle 20-30 °, the long 4mm of sword.
The ultrashort groove that the below is 1.5 times take a flute length as tool diameter further specifies content of the present invention as specific embodiment:
As shown in Figure 1, when printed board figure file was edited, take ultrashort groove center 1-2 as initial point, 2.0mil turned clockwise to ultrashort groove 1, form ultrashort groove rotating graphs 1-1, namely ultrashort groove rotating graphs arc center 1-1a rotates 2.0mil in the direction of the clock with respect to ultrashort groove arc center 1a.
When carrying out the bore operation of ultrashort groove, at first use conventional cutter to bore a centre bore 2 in ultrashort groove center 1-2 position, then use the specific type drilling tool, order by starter hole 3, end aperture 4, interstitial hole 15, interstitial hole II6 is holed, and finally form ultrashort groove 1, as shown in Figure 2.
