Vertical machining center realizes multi-face machining of parts

The problem of eccentric holes on the end faces of rotary parts is often encountered in production, and the usual method is to process them on a horizontal machining center. Parts with longer lengths are rotated by the table. The coaxiality of the eccentricity at both ends depends on the indexing accuracy of the table. For parts with shorter lengths, the manual rocking table is often used for indexing, and the eccentricity at both ends is the same. The degree of axiality is largely determined by the indexing accuracy of the turntable. Due to the limitation of the indexing accuracy of the turntable, the coaxiality of the two ends is not easy to guarantee for some parts with higher requirements. For this reason, we use the fourth axis rotation on the vertical machining center to better solve the problem of such processing. The specific method is to clamp the face plate with the indexing head on the vertical machining center, and complete the machining of the parts by the rotation of the servo indexing head. The processing method is as shown in the drawing.

This method can extend the processing range of parts to a variety of shaped parts and small box parts with holes and long grooves on the surface. The method of offset setting by the horizontal processing method is convenient to control the size of the part to the reference surface, and then through a series of roughing and finishing operations such as drilling, boring and milling, the drawing requirements can be achieved.

Summarizing the processing experience of various parts, we believe that: in the vertical machining center, by the arbitrary rotation of the angle of the rotating shaft, one-time clamping can realize the processing of drilling, boring and milling on multiple curved surfaces, so that some can only be lying in the past. Parts machined on the machine can also be machined on vertical machines. The processing range of vertical CNC machine tools has been expanded by converting horizontal machining to vertical machining.
