Choosing parts for a diy milling head

As an update / FYI for others on this spindle cartridge: this cartridge does not come with a sleeve and LMS does not sell the casting or sleeve for the KX3 () CNC mills. Unlike other cartridges, this one can not be used without the sleeve because it has exposed bearings (which are meant to fit into the sleeve). You can't see the bearings on "complete" cartridges.



In other words, that $250 for an R8 spindle cartridge is not such a good deal for a diy milling head (unless you are capable of milling your own sleeve). I couldn't find this part available anywhere else either.




LMS does sell the spindle and sleeve with casting for the KX1 CNC mill but it is a 2MT one that is only rated for a 500watt motor....

Now I am thinking that the Tormach spindle cartridges might be a better choice as they come ready to mount. You just need to buy the pulley and drawbar (which are cheap and available to buy). Their BT30 and R8 cartridges for the look to be good deals compared to any other option.




There are Chinese BT30 spindle cartridges available for less on eBay but by the time you pay for shipping from China, they end up the same price.




The R8 cartridge for the 770 is a little more expensive but it comes with the pulley and it is rated for 10,000 rpm. I haven't seen any 10,000rpm spindle cartridges available for anything close to the same price anywhere else, not even used ones.




Any deals on used cartridges on eBay are usually for 40 taper spindles and my assumption is that these are too big for your average small homemade mill....




A Tormach BT30 cartridge plus a used 1.5hp spindle motor with a diy cast iron mount sounds like a nice affordable and achievable diy milling head project.
