We have developed a CNC turning SPM, which does the OD turning, ID trepanning and end threading in a forged tube. It can enlarge the bore and makes the existing bore deeper. The bore produced by the SPM is smoother, uniform, and concentric. No drifting of the centre occurs, unlike in gun drilling, due to the self-guiding type specially developed tooling. The machine and the tool are robust to withstand extremely high cutting forces.Being a CNC SPM, it offers all the advantages of a CNC machine like operator friendly, HMI enabled quick & easy part programming, very high level of positioning accuracy & repeatability.High pressure, through coolant & generously large gashes in the cutter facilitates rapid chip evacuation from the cutting zone.
