Так как обрабатываемое отверстие может иметь изношенную поверхность, а также не иметь круглой формы, требуется выставить резец на минимальное касание (0,1 мм) к отверстию, и с чистовой подачей (0,05 мм/об.), провести обработку отверстия 2-3 раза.
Because processed hole may have worn out surfaces, and does not have a round shape, you want to set the cutter to the minimum touch (0.1 mm) to the hole, and with base flow (0.05 mm/Rev.), If you want to process the holes 2-3 times.
Since the hole can be processed by the wear surface, as well as not having a circular shape to expose the cutter requires a minimum landing (0.1 mm) to the opening, and a finishing feed (0.05 mm / rev.) To process the hole 2 - 3 times.
As processed by the opening can be worn surface, as well as does not have a circular shape, the cutter is required to obtain a minimum contact (0.1 mm) to the port, and finishing with the accelerator pedal (0.05 mm/on. ),A processing holes 2 or 3 times.
