CNC horizontal deep hole drilling machine is a machine tool that relies on specific drilling technology (such as gun drill, BTA drill, spray and suction drill, etc.) to drill deep hole series and precision shallow holes with a length diameter ratio greater than 10. The horizontal structure operating system uses CNC control, which is called CNC horizontal deep hole drilling machine.

How do horizontal deep hole drilling machines process ejector holes?

Then, how to use the horizontal deep hole drilling machine to process the ejector hole? Please continue to see:

1. Before machining the core shape with CNC deep hole drill, determine the position of the hole according to the coordinates of the workpiece hole. Using cnc deep hole drill to process the ejector pin hole from one side of the core is a common processing method of zui, which can ensure the accuracy of the hole.

2. When the core surface is complex, the location of the ejector pin hole should be determined according to the complexity of the surface. The shape of the core can be machined first to determine the position of the ejector pin hole. When machining holes with deep hole drills, the guide sleeve shall be consistent with the curved surface. However, there is a prerequisite that the curvature of the surface should not be too large. It is difficult for the guide sleeve to closely fit with the curved surface, and cutting oil will spray out, so it is not applicable.

3. When the requirements for the position accuracy of the ejector pin hole are not very strict, or when the pipe jacking structure is adopted, in order to ensure that the holes of the movable template, core, ejector pin fixing plate and movable template fixing plate are completely concentric, these plates can be fixed together. The fixed plate side of the driven template country uses a deep hole drill to process the hole. When the hole is only connected with the drill head from the core side, the cutting speed should be appropriately reduced to prevent the drill bit from breaking.
