Notes
Outline
The Axtrusion™ Concept
a new linear motion building block
Motive power and a precision
guide into ONE unit
Very Low Error Motion
Scales in Size Easily
ONE moving part
Very Robust
Background Material
Axtrusion Components
How the Axtrusion™ Works
The Bench Level Prototype
Bearing Selection
Way Surface Selection
Motive Power Selection
Carriage Load Capacity
Carriage Stiffness
Manufacturing the Carriage Base
(the casting)
Manufacturing the Carriage Base
(the machining)
Carriage Fixturing
Replicating the Bearing Pads into the Carriage
Assembly Lessons Learned
Center Fixturing Holes on Bearings
Two Fill Holes Per Bearing
No Vent Holes Needed
Design Carriage to use 1-2-3 Blocks for Fixturing
Build removal features into carriage base
DO NOT overfill the one of the bearing pockets and glue the carriage to the way.
