Abstract
The utility model relates to a cutting tool for printed circuit board (PCB), which comprises a cutter arbor (1) and a blade (2). The cutter arbor (1) is provided with a locating hole (3), one side of the blade (2) is positioned in the locating hole (3). Then the cutter arbor (1) is connected with the blade (2). The cutter arbor (1) can be connected with the blade (2) through the direct connection of the end faces. Because the PCB cuttingtool comprises two parts made separately, the grinding allowance is decreased, and the utilization ratio of the material is improved, and the cost is effectively reduced.
Description
Affiliated technical field
The utility model relates to the machining of printed circuit board (PCB), mills the cutting tool of processing in particular for the printed circuit twist drill.
Background technology
Along with constantly popularizing of technology such as the development of printed circuit board industry, particularly SMT, printed circuit board (PCB) develops to fine and closely woven wire pitch, micro hole, narrow and small ring width, multiple stratification direction, and is more and more higher to the requirement of the cutting tool of processing printed circuit board.For adapting to the processing request of printed circuit board (PCB), the printed circuit board (PCB) cutting tool generally all adopts high rigidity, the moulding of wear-resistant, expensive carbide alloy bar integral grinding at present, exist problems such as grinding allowance is big, manufacture difficulty is big, spillage of material is big, cause the cost of cutting tool high.
Summary of the invention
The purpose of this utility model provides a kind of printed circuit board (PCB) cutting tool, under the situation that does not reduce cutting ability, effectively reduces cost, reduces manufacture difficulty, improves working (machining) efficiency.
For achieving the above object, solution of the present utility model is, the printed circuit board (PCB) cutting tool is made up of knife bar part and knife edge part, knife bar part and knife edge part adopt respective material separately, machine-shaping respectively partly is provided with locating hole at knife bar, and an end of knife edge part is in the locating hole, partly be connected with knife bar, form one.
The knife bar part of the utility model printed circuit board (PCB) cutting tool is connected with the mode that knife edge part also can adopt end face directly to link to each other, and the end face of an end of knife edge part is connected with the end face of knife bar part, forms one.
Profitable effect of the present utility model is: because the printed circuit board (PCB) cutting tool is made up of two parts, so account for the knife bar part that the printed circuit board (PCB) cutting tool divides extremely greatly, the material that available rates is lower is made, adopt the knife edge part of carbide alloy then can select corresponding Hardmetal materials according to the size of its diameter, thereby reduced grinding allowance, reduce manufacture difficulty, improved stock utilization, reduced cost effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the side view of first kind of embodiment of the utility model printed circuit board (PCB) cutting tool.
Fig. 2 is the side view of second kind of embodiment of the utility model printed circuit board (PCB) cutting tool.
