Hi Everyone, I own and run an engineering and fabrication company with a high-end Auto tool changing CNC Lathe. We also have a few smaller CNC Mills, I will get to the point.
We are working on designing a BT30 Spindle with a capacity of up to 15,000RPM for a custom Vertical CNC Mill, the work area is roughly 0.95m x 0.95m we are still defining the Z height but we believe we will have a tall height to allow for 4 or even 5 Axis modules.
Right now we are only planning on making the CNC 4 Axis compatible with a controller that has capabilities of up to 6 individual servo motor outputs. We have been doing a lot of research on Servo-style spindles and we believe that is what we want to go with because it will allow us to automatically make threaded holes and allow us to have a lot more tooling capabilities as far as threading goes, the CNC Lathe will be a structure in Steel using 1/4 inch tubing and some rebar which will then be filled in with epoxy to help reduce vibrations and increase structural integrity. With all of those details behind us, we are currently looking at designing a BT30 Spindle with auto tool changing capabilities and forced cooling with air or liquid, We have just begun designing the spindle if anyone has any links to share for designs of the tool holders that would help us. we have found a few but they are all a little bit different. Once we are done with the spindle design we will run physic simulations on the spindle and share the plans here. Good day!
