How can deep hole boring head machining technology be improved?

Rocket body, artillery barrels, cylinder holes and axial oil holes of the shaft have high requirements for machining accuracy and surface quality, most of which are implemented using deep hole boring head machining technology. However, this technology is not everything, it still has a lot of places need to be improved.

Deep hole boring head machining in the toolholder by the limitations of the hole diameter, there is a length of large, small diameter characteristics, resulting in poor rigidity, low strength, cutting will also produce vibration, ripples and taper, which will affect the straightness and surface roughness in the deep hole machining is engaged in the machining of manufacturers should focus on solving the problem.

Deep hole boring head drilling and reaming, in order to reduce resistance, most of the use of lubricant to play a lubricating role, but there is no special device for cooling lubricant is difficult to enter the cutting zone, resulting in low tool durability, chip removal difficulties, which also requires deep hole machining manufacturers to pay more attention to and make improvements.

In addition, deep hole boring head machining requires experienced workers to operate, because the machining process can not directly observe the cutting of the tool, not experienced enough workers can not correctly determine whether the cutting process is normal or not, which also affects the smooth running of the cutting.
