  • ggod one.

    one Al piece bored at both ends and fitted the collect along with the ball bearings.now how did u lock the collect on the top side.

    and whats the power of the spindle motor

  • Thanks, the spindle housing is steel with an Al heatsink pressed on. The shaft is a straight shank ER16 chuck which has a collar at the bottom that prevents it from being "pushed into" the bearings. A ring is then glued to the shaft above the bearings pushnig the inner races together and preventing the shaft from "falling out" of the bearings. A flange at the bottom holds the outer races and provides preload. I was sceptical about gluing but it has worked years. Motor is 3phase, 1.1kW

  • Henrol ? could you give me the program xD?

    ( Codes and shit ) I want to try it to ^^

  • If you mean the G-code program I'm not sure I have it anymore, besides it would be too long to post here...

    If you mean 'codes and shit' for Mach3 then the answer is no - sorry. There's a working demo available at their site which is more than enough for a testrun and even for most basic home-shop machining.

  • i am wanting to get into cnc milling for my flight sim parts but I don't yet understand alot of it can you tell me what is the tool used is it a router? and what are the bits?

  • Hi,

    The spindle is built from a straight shank ER16 collet chuck, a turned housing and three bearings. It is driven by a 1.1kW three-phase motor via a belt. I did use a BOSCH router at the beginning but it had its drawbacks. Alot depends on what material you're going to cut.

    The 'bits' I use are various types endmills, there's a lot of different types available depending on type of material etc.

see all

  • thanks for the reply.

    it would be much better if you could post a line diagram of the spindle assembly.

    just for understanding.

  • Real nice!

  • Very nice work ! but some coolant fluid nozzles would make it even better
