Considerations of Deephole Drilling Processing

There are some considerations during deephole drilling processing.

1. Deephole drilling processing can not observed tool cutting conditions directly, can only listen to the sound, see the chip, observe the machine load and cutting fluid pressure to determine the chip and tool wear.

2. Deephole processing cooling is difficult, we must use effective and reliable cutting heat cooling.

3. Deep hole processing chip removal is difficult, if chip jamming damage the tool easily, therefore, it must be a reasonable choice of cutting parameters to ensure reliable chip breaking and smooth chip.

4. When carry out deep hole machining, hole prone to deflection, so we should consider during design of the tool and into the fluid structure.

5. Long rod, poor rigidity and vibration will directly affect the machining accuracy and production efficiency, therefore a reasonable choice of cutting parameters is very important.
