How should the machining challenges of CNC deep-hole drilling and boring machines be addressed?

Release time:

2016-12-29

CNC deep-hole drilling and boring machines are characterized by high precision, high efficiency, and a high degree of automation. When equipped with advanced drill bits such as gun drills, BTA drills, and jet–suction drills, they can complete in a single continuous operation processes that would normally require separate drilling, reaming, and broaching on conventional machine tools. However, during deep-hole drilling, these machines face challenges such as poor heat dissipation and difficult chip evacuation; moreover, the slender drill rods often exhibit poor rigidity, making them prone to bending and vibration. To address these issues, a hydraulic cooling system is typically employed.

How should the machining challenges of CNC deep-hole drilling and boring machines be addressed?

CNC deep-hole drilling and boring machines are characterized by high precision, high efficiency, and a high degree of automation. When equipped with advanced drill bits such as gun drills, BTA drills, and jet–suction drills, they can complete machining operations—such as drilling, reaming, and broaching—that would normally require multiple separate processes on conventional machine tools—in a single continuous cutting pass. However, during deep-hole drilling, these machines face challenges such as poor heat dissipation and difficult chip evacuation; moreover, the slender drill rods often exhibit poor rigidity, making them prone to bending and vibration. To address these issues, a hydraulic cooling system is typically employed.

In machining, holes with a depth-to-diameter ratio greater than 6 are generally classified as deep holes. Twist drills can be used for such operations, as they facilitate coolant penetration and produce fine chip curls that are efficiently evacuated by the drill.
