The method of processing the corners and faces of the parts is different for each position. But do you know what methods are available for machining flat contours for precision parts? (1) Plane contour processing method: The plane contour is composed of straight lines, arcs or intermediate curves. These planes are parallel or perpendicular to the bottom lower plane of the fixture. Usually two semi-axes are used for coordinate machining on a three-axis milling machine. (2) Fixed bevel plane processing method: Fixed bevel refers to the bevel that forms a fixed angle with the plane. When the size of the part is not large, the oblique shim can be flattened and processed. Precision parts processing can also use a three-axis machining center, using end mills, ball-end milling cutters or drum milling cutters in the form of linear or arc interpolation to perform layered cleaning processing to remove residual areas. What are the processing methods for precision parts processing flat contours (3) Oblique plane processing method: For inclined surfaces with small curvature changes, use a four-axis linkage machining center with a swingable spindle for processing. When machining, please make sure that the bevel plane of the cutting tool and the part is always suitable. For bevel angles with large curvature changes, the five-axis machining center should be used to process the angle by circular interpolation. The above is the method for processing the contour of the precision parts. When processing, ensure that the conditions for plane processing can be selected and then choose what method to process to ensure the damage of the parts.
