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

Industry Standards

High End

Budget

Existing Open Source Designs

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

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

Outer Casing

Cap

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

BOM
