How to Select Deep Hole Drilling?

Deep hole drilling is used for the hole of high precision, low surface roughness, need adopt drilling, boring, rough cutter, grinding and other procedures. Deep hole drilling process exists heat and chip difficult problem, meanwhile, the elongated rod leads to poor rigidity, easy to produce bending and vibration, therefore it needs a cooling system to solve the problem of cooling and chip removal. How to choose deep hole drilling?

1. Good cooling effect, eliminate the drill pipe deformation and heat generated by friction, prevent BUE.

2. Good high temperature lubrication, reducing friction and wear of the tool and the support frame, at a high temperature of cutting zone, ensure that the tool can still maintain good lubrication.

3. good permeability and chip evacuation capacity.
