Selection Requirements for Cutting Fluids for Deep-Hole Drilling Machines

Release time:

2016-12-23

Deep-hole drilling machines are specialized machining equipment designed for three-axis drilling, characterized by high efficiency, high precision, and a high degree of automation, and they employ external chip evacuation to drill small-diameter holes. With a single setup, these machines can achieve the same machining results that would normally require multiple operations—such as drilling, reaming, and broaching—on conventional machine tools. The machining accuracy of deep-hole drilling machines ranges from IT7 to IT10, with a surface roughness of Ra 3.1 to 0.04 μm and straightness tolerances of no more than 0.05 mm per 100 mm. Given these numerous processing advantages, what requirements does a deep-hole drilling machine impose on cutting fluids?

Selection Requirements for Cutting Fluids for Deep-Hole Drilling Machines

First, it must provide effective cooling. This is essential for mitigating workpiece deformation and the heat generated by friction between the workpiece and the machine tool cutting tools, as well as for suppressing built-up edge formation.

Second, it exhibits excellent high-temperature lubricity, ensuring that the cutting tool maintains effective lubrication even under the high temperatures in the cutting zone, thereby reducing wear on the cutting edge support.

Third, excellent penetration and chip evacuation are essential; ensuring smooth chip removal is the most fundamental and critical function of cutting fluid. The cutting fluid must exhibit good penetrative properties to promptly reach the cutting edge, thereby facilitating efficient chip evacuation.
