The following 3 axis base cnc machine had been designed with VariCAD:
- workspace XYZ: 500x500x300
- max 30kg table load
- max feed rate 80mm/s
- positioning accuracy +/-0.01
- repeat accuracy +/-0.02
- max tool diameter 10mm
- usable materials: plastics, light alloys, steel
- max electrical power consumption: ~4000W (3 phase, 400V, 50Hz)
- external dimensions WLH: 1500x1400x1800
The accuracy values must be checked after construction! There is possible to increase the accuracy with more precise parts (e.g. C3 class ball screw instead of C7, etc), more precise machining than the prescribed on the drawings, but this is not sure to be economical in hobby category.
The style is directly were designed as welded steel structure and not aluprofile style light structure, because of more suitability to work with steel.
The size of the workspace makes the machine suitable for general works, equipped with printing head there will be chance to enter more serious possibilities!
Covering the X linear guides and ball screw is a special job, it must be solved individually, because everybody has different "most suitable" parts..
The automatization and electrical system must be perform as You like!
