 Positioning method and the knife point: positioning methods can be divided into two; one is in the position of the porous CNC drilling, two outer positioning. Positioning for craft makers are also very important, usually in pre-production on the board shall determine the location of the program. Locating the most general method. The so-called internal positioning is to choose the mounting holes in the sieve CNC PCB drilling, pluggable holes or other non-metallic hole as a positioning hole. Sought the relative position of the hole on the diagonal and possible selection of large diameter holes. You can not use metalized holes. Because of differences in the hole plating thickness will affect the consistency of your chosen positioning holes, while when taking board is likely to cause damage to the hole and the hole surface coating edge CNC drilling, to ensure that the conditions under PCB positioning pin number The less the better. Generally small plates using two pins, the board using three pins, the advantage of accurate positioning, plate shape deformation good shape small CNC precision drilling, milling speed. Its shortcomings boards of various kinds of multi-aperture pin of various diameters need to get ready, as there is no available position within the plate hole, when discussing the need for pre-production board with positioning holes in the more, the more cumbersome and customers. Meanwhile paneling template for each different management board is more troublesome, expensive. Cooling alloy drill Features: Alloy drilled from the structure as a whole can be divided and split (Figure 1 in the split cooling alloy drill). Monolithic carbide materials used in all, split only the head with carbide, then still part of the guide portion and holding high-speed steel. Since the cemented carbide drill material mainly containing W, Ti, Ta earth metal element, and therefore the hardness of cemented carbide drills, wear resistance and heat resistance are higher than those of ordinary tool steel. In general, hardness of cemented carbide in 90HRA above, heat resistance above 850 ℃.
