About Double Spindle Deep Hole Skiving Roller Burnishing Machine

1. Machine overview

Our deep hole skiving roller burnishing machine machine is an alternative to conventional deep hole boring machine. By combining rough boring, precision boring and roller burnishing into a single integrated process, this machine completes rough and fine boring during forward feeding, and performs burnishing during retraction, showing significant advantages:

Ultra-high efficiency, fewer processes. Completes all steps in one pass, drastically cutting cycle time.
Superior accuracy & surface finish. IT8 dimensional tolerance, with surface roughness down to Ra 0.050.4 m.
Enhanced surface hardness. Burnishing improves the workpiece surface hardness by more than 50%, boosting wear resistance and service life.
Eco-friendly & labor-saving operation. Low noise, zero pollution, and minimal manual intervention.

The machine has two spindles, capable of machining two workpieces a time. The machine bed is manufactured by high quality cast iron, with strong rigidity and strong stability. It is also equipped with large capacity automatic chip removal machine, drum magnetic separator, collect automatically iron intoattle box, cooling fluid can be recycled by precision filtration. The optional CNC systems such as SIEMENS, GSK, FANUC.
