Hi there! I bought some time ago a ratrig stronghold pro, with a router11, but I find myself limited by the ER11 collet. This limitation opened the pandora box of spindles, clearly. Now I am thinking of getting an aircooled spindle, in particular this setup: - Teknomotor HF Spindle C4147-C-SB-P-ER20-2.2kW-18.000rpm - VFD022E21A 1x230V-3x230V 2.2KW from damencnc.com. They offer to setup the spindle to the VFD, which sounds great. The problem is how to attach this to my Z plate, or better, how to get a plate that would be both compatible with the CNC setup I have and this spindle, or similar. Did anyone got into this rabbit hole and could share how they solved it? Am I totally tripping with these thoughts of getting and air cooled spindle? I excluded the water cooling that Ratrig solution offers because I don't want any water stress on a non professional setup like this, and want to be able to leave the machine to work an hour without stress of water damage/electricity.
1.5kw air cooled 65mm spindles fits the same mount. 2.2kw is quite overkill: How to calculate V-Slot® deflection - frame will flex long before you excert 2.2kw of power into the material (cutting force opposed by rigidity of the frame - otherwise just chatter)
Ah that's super helpful! You seem to have a spindle or two in mind with these specs, could you recommend them? I was hoping to find something in a EU shop, and assumed a fancy German brand would do a better job, but yeah any recommendation welcome!
