Open Source CNC Spindle

Basics

• The Core of a CNC Mill
• Uses various toolheads to cut, mill, finish, and otherwise change blanks into filalized parts
• Can acheive high speeds, while at the same time having high torque
• Also can incorperate some sort of Automatic Toolchanging Chuck to hold various endmills/milling cutter/bit (Need a standardised word to be agreed upon before the page can be made), measuring devices such as an Edge Finder or Indicator (Measurement Tool), or a cleaning device such as an vaccum cleaner hose, an air nozzle, or a brush for automatic cleaning of chips/dust
• May also include lubrication outlets, or attachment points for these hoses
• Can be air cooled or liquid cooled

Minimum Viable Product

• Air cooled and liquid cooled options
• Options with and without toolchangers
• Optional toolchanger adapter add-on
• Can handle cutting cold rolled steel in a similar extent to high end models (as well as do other challenging tasks of a similar level)

Basic Design

Motor

• Three Phase?

Bearigs

• These are the real key to stability from the strong axial and radial loads
• Air Bearings and Axial Ball Bearings

Seals

• Labyrinth Seals as well as minor positive pressure via air/gas pump
• This is key to keep dust out, as cnc mills are an inherently dusty enviroment due to chips and dust being produced

Air Cooler

• Passive, Active (Compressed Air Flow)?

Water Cooler

• Internals are most likely custom, but the externals can easily be bought as plumbing parts, or PC Watercooling Parts
• See Also Open Source Water Chiller

Chuck

• Either a manual chuck
• or an Automatic Toolchanging Chuck

Cap

• Has air, suction, (Water if included), and power/data inputs
