Im building a 120" x 12" x 12" cnc drilling setup for predominantly steel. i produce alot of linear parts and want a spindle setup that can run along a line as opposed to material movement. i have the majority of it worked out but am having difficulty finding the appropriate spindle/reducer to manage the speeds im looking at. the range im trying to achieve are 350rpm-3500rpm. most of the spindles im finding, the low is at 10000rpm. im not opposed to building in a reducer but dont know enough about how that would affect the torque. Ideally it would incorporate a vpn to dial in the speeds. I have reached out to several companies on alibaba but those that have low speed options seem to be low wattage, again, my knowledge in this is low, but i need something that can match 1.5-2hp for some of the drilling processes that im woring with. Straight drilling im using mostly cobalt, and for drill/tap i use a flowdrill setup.
Is this possible? any advice would be great. Also, this will be a system that will build as it develops, and the programming is taken care of.
