Why should the lathe drive
3, with the vertical milling process, will also be due to the milling cutter grinding the actual size of the change; installed knife, not necessarily completely with the spindle concentric, resulting in changes in the size of the cutter when the rotation.
Vertical, which will cause the disk cutter in the rotation will produce left and right deflection, resulting in the actual cutting width is greater than the cutter marked knife size (or measurement size).
2, with the horizontal milling, the knife row (also called the arbor) always radial runout, which will cause the disk cutter in the rotation when the actual size of the turn; disk cutter in the installation can not guarantee completely with the spindle
1, the accuracy of the machine is always impossible to 100% accurate, especially the screw drive, the gap is not exempt.
