How does CNC process oblique holes?

CNC machining is the most widely used method for hand model making, among which CNC machining center is the most widely used. CNC machining center is under the control of the machine tool control system of the automatic tool changer, through the setting of the workpiece processing program, in the case of unattended , complete complex three-dimensional space processing such as boring, drilling, reaming, tapping and milling at one time. How does the CNC hand factory process oblique holes during production?

First, rotate first and then translate

Second, first translate and then rotate

3. Combination of first translation and then rotation and first rotation and then translation

  Then, when the CNC prototype factory is doing processing, there are still several issues that need to be paid attention to:

Before drilling, the end surface of the workpiece must be turned flat.

When the drill is about to penetrate the workpiece, the feed rate must slow down.

When drilling small holes or deep holes, since the chips are not easy to discharge, the drill bit must be withdrawn frequently to remove chips.

When drilling small holes, the speed should be increased.

When finishing the inner hole, the blade should be kept sharp.

When turning flat-bottomed holes, the tool tip must be aligned with the center of rotation of the workpiece.

When machining oblique holes in CNC handboard factories, which of the above methods should be used depends on the dimension of the workpiece drawing, and the processing requirements and shape and position tolerances marked on the oblique holes in the drawings shall prevail, in order to improve the processing accuracy and processing efficiency. Purpose, flexible choice. When CNC machining holes, once the positioning method of the part is determined, it is only necessary to correct the X, Y, Z mechanical coordinates of the positioning pin or the positioning surface and the rotation angle B of the leveling tooling table, and the irregular machining can be carried out. The processing of the inclined hole is done.
