What Cutting Oil Is Used for Deep Hole Drilling Metal?

Deep hole drilling (gun drilling) is a deep hole processing process developed in recent years. Traditional deep-hole processing (hole depth to aperture ratio greater than 5), the need for drilling, boring, coarse articulation, grinding and other multi-process ingestion to process more high precision and lower surface roughness of the hole. The new process is the use of special lying tools and high-pressure cooling lubrication system, which can be reduced to a continuous walking knife to complete a very deep high-precision and low surface roughness of the hole processing, this process is high efficiency, significant economic benefits.

The high-performance deep hole drill cutting fluid is one of the key semen drilling technology, and the deep hole drill cutting fluid must have the following properties:

1) Good cooling, eliminate the heat generated by deformation and friction, inhibit the formation of debris tumor.

2) Good high temperature lubricity, reduce the friction alt-cutting wear of the cutting edge and support, to ensure that the tool in the cutting area of high temperature to maintain a good lubrication state.

3) Good permeability, chip removal, so that cutting fluid can penetrate into the cutting edge in time, and ensure that chips can be smoothly discharged. Therefore, deep hole drill cutting fluid requires high extreme pressure and low viscosity.
