    Bore oversize - HMC

    in CNC Applications

    Dear Experts

    We have a HMC machine wherein we have problem of bore getting oversized.

    We have checked following:

    Tool clamping force inside Spindle

    Run out on test mandrel for HSK63 checked both at nose as well as at 250mm

    Taper along test mandrel checked

    Component clamping on fixture found alright

    Overhang of boring bar

    Tool replaced with new one

    Cutting parameters checked and found ok vis a vis original program of the machine

    Request to suggest us check points to overcome issues like Bore oversize, Ra,Rz (Surface finish) more than permissible limits, Chattering in Bore and taper along z axis

    Regards

    I am not sure where to start. Is this a job that has been running properly in the past and only now the problem has come up? If so, obviously something has changed, but I cannot comment on what it might be. Sounds like you have checked all the likely potential causes. Maybe the boring bar manufacturer could help?
