CNC Tube Plate Deep Hole Drilling

CNC tube plate deep hole drilling are mostly surrounded by the working surface of the tool. Therefore, there are problems such as rigidity, chip removal, guiding and cooling lubrication of the tool.

CNC Tube Plate Deep Hole Drilling

CNC Tube Plate Deep Hole Drilling:

(1) Before drilling, pre-drill a shallow hole with the same diameter as the drill bit, which can guide the centering when drilling. This step is especially necessary when machining small holes with high straightness requirements.

(2) When installing and debugging the machine tool, ensure that the center axis of the workpiece hole coincides with the center axis of the drill pipe.

(3) According to the material of the workpiece, the cutting amount is reasonably selected to control the degree of chip curling, and C-shaped chips which are favorable for chip removal are obtained. When machining high-strength material workpieces, the cutting speed V should be appropriately reduced. The amount of feed has a great influence on the formation of chips, and a small feed can be used under the premise of ensuring chip breaking.

(4) In order to ensure the drainage and cooling effect, the cutting fluid should maintain proper pressure and flow. High pressure and small flow rate can be used when processing small diameter deep holes, and low pressure and large flow rate can be used when processing large diameter deep holes.

CNC Tube Plate Deep Hole Drilling

ALLES CNC tube plate deep hole drilling are mostly surrounded by the working surface of the tool. Therefore, there are problems such as rigidity, chip removal, guiding and cooling lubrication of the tool. The drill bit of the deep hole drilling machine has poor rigidity and is easy to "bias" when drilling. This is because the diameter of the drill bit is limited by the machining hole, and the drill bit is generally long, and at the same time, it is required to have the largest possible chip on the drill bit. The groove facilitates chip evacuation, which makes the core thinner and thus less rigid. Due to the rigidity and guiding of the drill bit (drilling, only two narrow edges of the drill bit are in contact with the hole wall), the two main cutting edges are difficult to be symmetrical, and the radial forces cannot cancel each other out. Moreover, the first contact with the machined surface during drilling is the chisel edge with a large negative rake angle, which makes it difficult for the drill bit to enter the cutting. Therefore, the drill bit is prone to "biasing" when drilling, resulting in the axis of the drilled hole. Skewed or enlarged aperture, not rounded, etc.
