Boring and surfacing complex PIONER RNK is designed to restore worn out holes. It allows not only boring, but also surfacing. The work is done in three stages:
1. Boring a worn hole to eliminate ellipse.
2. Surfacing to restore the metal layer.
3. Final boring to the required size.
The machine is mobile, so all work can be done at the location of the special equipment.
Mobile surfacing machine Sarmat NK750 is used to repair worn holes. To eliminate ellipse, a boring machine is used, and after that, surfacing is performed. It is for this stage that a surfacing machine is required. Unlike the mobile machine Sarmat NK450, this machine performs not only internal surfacing, but also external one.
Minimum quantity for "Mobile surfacing machine SARMAT NK750" is 1.
Mobile surfacing machine Sarmat NK450 is used to repair worn holes. The hole needs to be bored first to eliminate ellipse. After that, the surfacing machine can be used. For the final restoration of the original diameter, boring is again used.
