Re: OKUMA MU400VA OSP-P200 MH Large and heavy tools
hy
... heavy atribute reduces arm swing speed
... large atribute checks for atc neighbour pots to be empty
* thus, neither is related to spindle clamping
does the weight of your toolholder+tool<maximum allowed for your machine ( values should be listed inside the operation&maintenance manual, and also inside machine catalogue ) ? if yes, then maybe :
... your spindle clamping power has reduced; broken elements maybe ?
... your toolholder does not make proper contact with the spindle taper
... pulstud needs to be replaced
... there is a lack of balance, even if rpm is low
if i understood right, that the tool does drop/fly-off, i would recomand checking spindle's retention force, taper contact and claws condition ( those that grip the pullstud ) / kindly
