• 4# - Spindle head and pneumatic cylinder for ATC

  Adrian Prinz • 08/25/2021 at 13:46 • 0 comments

  The spindle head is made of lasered plates and holds the spindle cartridge (old version of the spindle flansh in the picture below)
  

  Assembled spindel head (old version of the water cooling):

  Spindle belt drive:

  Self engineered pneumatic cylinder for the draw bar:

  All assembled and painted (cylinder fixture is temporary..):

• 3# Spindle head and X-Y-table

  A belt pulley was adapted to the 2.2 kW Spindle motor (China Spindle - used as motor) to drive the spindle cartridge

  Components for the X-Y-table were machined on the lathe

  Side stiffeners for the z column (lasered plates)
  

  Assembled Z-axis, side stiffeners and X-Y-table

• 2# Z-Axis and Spindle

  The back of the Z-Axis was casted in UPH concrete

  At this point i decided to go full in and build up the overall machine from scratch. I designed it in CAD and continued with the Spindle cartridge, since it is the most difficult part.

  Turning the cartridge
  

  Grinding the cartridge

  Turning the spindle shaft

  Machining the draw bar

  Finished draw bar (hardend to about 54 HRC - C45k)
  

  Spindle watercooling mandrel

  Finished spindle cartridge (after some iterations.. :) )
  

  Assembled in the spindle holder

• 1# Base material and first parts - project idea

  Adrian Prinz • 08/22/2021 at 14:31 • 0 comments

  Without the actual intention to build this machine at the beginning, I started of with random cut offs from ebay. (Just planed to improve my former CNC milling machine)

  I cut the components roughly to length..

  First I  used the bench top lathe (that was borrowed to me for a different project :) ) to get the dimensions of the parts on point

  First finished parts...
  

  Critical dimensions (bearing seats) were machined on the bench top lathe

  All components were machined just by using basic tools and the bench top lathe - no milling machine involved :)
  Test fit of the components..
