Abstract
The utility model provides a special milling-cutter for printed circuited board, comprising a hilt 1, a milling blade 2 and a drilling blade 3. The utility model has the advantages that the surface cut has high degree of finish, the diameter of the tool and the length of the blades can be set as needed and the tool can be used repeatedly and can be used for waste utilization. The milling-cutter has low cost and long service life and can save considerable capitals for enterprises and create good economic benefits.
Description
Technical field
The utility model relates to the milling tool technical field, specifically a kind of special-purpose milling cutter for printing circuit board.
Background technology
In PCB (printed circuit board) industry, adopt diamond pattern tooth or helical tooth cutter during each factory process plate periphery usually.The milling ability of a milling cutter generally only is about 40 meters.Costing an arm and a leg of milling cutter, and can not regrind, cost is high.From being cut face fineness: expensive high-grade CNC milling machine milling effect is better, but it is few in number to have high-grade CNC milling machine factory; The CNC milling machine milling effect of general class can not show a candle to high-grade CNC milling machine, this class milling machine just that can present most of factories adopts.Moreover, be generally to satisfy and produce needs, factory's storehouse is stocked the milling cutter of plurality of specifications, multiple model, and fund input is bigger for this reason, and needs to be equipped with certain storage area.
The content of utility model
The purpose of this utility model is that design a kind ofly can utilize waste and old bit sub, and blade is the special-purpose milling cutter for printing circuit board that uses of grinding repeatedly.
The utility model special-purpose milling cutter for printing circuit board comprises handle of a knife, milling edge, drill lip.
Milling edge can be single-blade, twolip, three swords.
The tool cutting edge angle of milling edge is 35～75 degree.
The advantage of the utility model special-purpose milling cutter for printing circuit board:
1. it is highly polished to be cut face.Can do experiment as follows: on two milling spindles of twin shaft CNC milling machine, difference clamping PCB milling cutter and conventional milling cutter, the similar workpiece of milling simultaneously.The effect of milling is: the smoothness with PCB milling cutter milling panel edges is higher than conventional milling cutter far away.
2. tool diameter and sword length can set up on their own.Be generally to satisfy and produce needs, factory's storehouse is stocked the milling cutter of plurality of specifications, multiple model, and fund input is bigger for this reason, and needs to be equipped with certain storage area.The PCB milling cutter is then different, its can settle a dispute by the parties concerned themselves at any time according to actual needs specification and relevant parameter problem of milling cutter, thereby can fundamentally avoid drawback such as big such as investment, that buying is loaded down with trivial details.
3. can use repeatedly.Conventional milling cutter belongs to disposable use cutter, and its milling life-span generally only is a rice surplus in the of 40, promptly scraps after the wearing and tearing of milling cutter.The PCB milling cutter then can be realized using repeatedly, and these can be from two phase analyses: the one, and when using for the first time, its milling life-span and conventional milling cutter have no difference; The 2nd, after every processing once, just its life-span increase a life cycle, as handle proper, but milling cutter repeated treatments several times.So, the PCB milling cutter milling life-span can surpass many times on conventional milling cutter.
4. can twice laid.Each PCB factory all uses thousands of or ten hundreds of carbide drills every year.Waste and old bit sub is not worth a farthing, and many producers mostly abandon.The present invention utilizes these waste and scraps not to the utmost that are easy to get, use to make the PCB milling cutter.Drill bit that these are waste and old or waste and old conventional milling cutter use fully, give its new use value, the milling cost of PCB can be reduced more than 90% the annual economic benefit of bringing to enterprise, several ten thousand yuan at least, hundreds of thousands unit at most.
Description of drawings elaborates to implementing patent below in conjunction with accompanying drawing.Fig. 1 is that special-purpose milling cutter for printing circuit board structure chart Fig. 2 is a single-blade milling cutter sectional view.Fig. 3 is a twolip milling cutter sectional view.Fig. 4 is three blade milling cutter sectional views.
Specific embodiment
Embodiment one:
According to Fig. 1, shown in Figure 2, utilize waste and old carbide drill handle on special equipment, to grind the single-blade milling cutter, the tool cutting edge angle β of blade is 50 degree, lip angle α is 130 degree.
Embodiment two
According to Fig. 1, shown in Figure 3, the course of processing is the same with embodiment one.Just grind the twolip milling cutter, the tool cutting edge angle β of blade is 40 degree, and lip angle α is 130 degree.
Embodiment three
According to Fig. 1, shown in Figure 3, the course of processing is the same with embodiment one.Just grind three blade milling cutters, the tool cutting edge angle β of blade is 60 degree, and lip angle α is 130 degree.
Claims (2)
1. a special-purpose milling cutter for printing circuit board comprises handle of a knife (1), milling edge (2), drill lip (3), it is characterized in that milling edge (2) is single-blade or twolip or three swords.
2. special-purpose milling cutter for printing circuit board according to claim 1, the tool cutting edge angle β that it is characterized in that milling cutter are 35～75 degree.
