Machining tool machining mainly on what to choose? Below small for everyone to explain:
 Milling tool selection. Parts machining surface, in order to ensure cutting edge and contour cutting point tangent, but avoid interfering contour of the blade and the workpiece, the general ball knives, edged cutter with roughing, semi-finishing and finishing with four-blade cutter; when milling larger plane, in order to increase productivity and improve the surface roughness, the general mosaic disc cutter blade; commonly used generic milling cutter when a small plane or a stepped surface; when milling keyways, in order to ensure the dimensional accuracy of the groove, usually with a two-edged groove cutter.
Of cut back (or side of cut) is determined. In ensuring the quality of the machined surface of the premise, the back of cut (ap) should, according to the machine tool, workpiece and tool rigidity to decide, in the stiffness of the permit conditions, should be possible to take the knife back allowance amount equal to the workpiece, this can reduce the number of passes, and improve productivity.

Hole machining tool selection. CNC machine tools in general no drill hole machining mode, due to the rigidity of the drill cutting conditions and poor selection of drill diameter D L / D≤5 (L for drilling depth) conditions should be met; first diamond drill before positioning the center to ensure that the hole positioning accuracy machining; former fine twisted optional floating reamer, reaming before opening to be chamfered; boring should try to use a symmetric multi-blade cutting head boring, boring to balance vibration; try to choose a thicker and Arbor shorter to reduce cutting vibration. CNC machining in the economy, due to sharpening knives, measuring and replacement, mostly carried out manually, taking auxiliary longer, therefore, must arrange the order of the tool.
