Why choose the Halnn Solid CBN inserts to process rolls ?
Compare with common cutting, heavy-duty cutting tool has the characteristics of large cutting depth, relatively low cutting speed and relatively slow feeds, so its processing technology is very different from ordinary mechanical cutting process.These processes Characteristics exist in the rigidity of the machine, reducing the stability of the performance, the choice of tools, tool installation, the choice of cutting condition, workpiece clamping and others; especially processing high hardness heavy parts is most difficult.
Advantage
Halnn recommends solid CBN tools that can withstand large margin cutting. It is more stable than traditional cutting tools, and the production cost is increased. The application of dry cutting greatly reduces the production cost.
