The difference between milling and reverse milling in cnc CNC machining center
The direction of rotation of the contact between the milling cutter and the workpiece is the same as that of the workpiece feed direction, and vice versa.
There is always a large or small gap between the nut and the screw of the milling machine. If the table moves to the right, the screw and nut are close to the left and the gap is on the right side, and the horizontal milling force To the right, so when the horizontal milling force to a certain extent will push the table and the screw together to the right to move
eave the gap on the left; as the screw continues to rotate, the gap back to the right, in this The moment the table to stop the movement; when the horizontal milling force is large to a certain extent, there will be to promote the table and the screw again to the right of the movement.
This periodic movement makes the table movement is very unstable, easy to cause the knife Teeth in the milling, forging, the first contact with the black teeth, aggravating the tool wear; but the vertical milling of the milling force will force the workpiece to the table, the tooth and the machined surface sliding
