hi. everybody
i have problem with setting zero point on the subspindle on my HT20SII cnc lathe with seicos multi control , i have this lathe for while and no need to use subspindle since today , i have to machine some parts and i need to do transfer part from main spindle to sub spindle , setting "0" point for B axis is no the problem but i don't know how to set "0" point datum on the subspindle i have no manual for subspindle , so anybody might have subspindle manual for hitachi seiki HT20SII seicos multi control , or any advice how to set datum on subspindle.
many thanks for any reply
