hi,
my name is matt and i am new to your community. i work for a sign company and we have a larken 24x24 CNC router. it is equiped w/ a technomotion 3hp spindle and it has a er-25 collet. i machine face of signs and it takes forever w/ a 1in end mill. (thats the biggest i can find for my collet). i was looking into shell mills but i see that the bigger ones (3in and above) need to be used in a r8. my question is can i convert my spindle into an r8?
thansk in advance,
matt
