The following process measures can be taken during processing depending on the specific processing requirements:
(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) When starting drilling, first open the cutting fluid pump, then start the lathe, cut the cutter, end the drilling or when the fault occurs, stop the cutter first, then stop, and finally close the cutting fluid pump.
The cutting force is evenly distributed, and the breakability and chip breaking performance are good, the drilling is stable and reliable, and the deep hole drilled is good in linearity.
1. Deep Hole Drilling Machine can't directly observe the cutting condition of the tool. Therefore, the wear and the tool wear condition can only be judged by listening to sound, looking at the chip, observing the machine load and cutting fluid pressure.
2, processing heat is difficult, must use effective and reliable cutting thermal cooling.
3, processing is difficult, such as the occurrence of cutting block is very easy to damage the tool, so the cutting amount must be reasonably selected to ensure reliable chip breaking, smooth chip removal.
4. The hole is easy to be skewed during processing. Therefore, the guiding device and measures should be considered in the design of the tool and the inlet structure.
5. When the CNC Deep Hole Drilling Machine is processed, the drill pipe is long, the rigidity is poor, and it is easy to vibrate, which will directly affect the machining accuracy and production efficiency. Therefore, it is very important to choose the cutting amount reasonably.
