How about the milling technology of CNC precision parts processing

CNC precision parts processing still involves a wide range of fields. How can you say that? In fact, everyone sees it in everyday life. The effect is remarkable, and it will be more applied in some industrial equipment. Understanding the machining requirements of CNC precision parts machining is also high. Why, because the customer is specifying the quality, and the advantages of this kind of part machining are great, so it is necessary to guarantee a stronger and more trustworthy customer. This is CNC precision. Parts processing needs to be guaranteed.

CNC machining center milling the cutting surface of a plan view part

When milling flat parts, the side edge of an alloy milling cutter is generally used for drilling. In order to reduce tool marks and ensure the surface quality of the part, the in and out procedures of CNC inserts need to be carefully planned.

When milling the outline of the outer surface, the cut-in and cut-out points of the turning tool should be cut into and out of the surface of the part along the extension line of the contour curve of the part, and the part should not be cut in reverse immediately to prevent the production and processing surface from being scratched and ensure that the parts are generally lubricated.

When milling a closed inner surface, if the inner surface is in line with the extension, it should be cut in and out tangentially. If the inner contour curve is different from the unexpected ductility, the CNC insert can only cut in and out in the opposite direction of the inner contour curve and set its in and out points at the intersection of the two elements.

Partial outline. When some internal elements intersect without intersecting points, in order to prevent gaps at the general corners when the tool compensation is canceled, the entry and exit points of the CNC blade should be avoided at the corners.

When the arc tool radius compensation is used to mill the outer circle, it is displayed as the infeed road surface. After the full circle production and processing is completed, the tangent point is not fed, but the CNC blade is strengthened by a distance along the tangential direction to prevent the CNC blade of the machining center from colliding with the surface of the workpiece. Cancel the product workpiece at the time of tool damage stop, and cancel the product workpiece.

When milling internal arcs, the rule of cutting in from the radial direction should also be followed. A better method is to connect the mechanism from an arc to an arc-shaped production machining path, there by improving the machining accuracy and production machining quality of CNC precision parts with internal thread surfaces.
