Technical comparison · Turning (lathe)

The differences that matter
- Price: about 2,900 € against 3,300 € → the 8400B costs 400 € more for the same lathe.
- Mechanics, speed and control: identical → the choice comes down to what the package contains.
Which one to choose
Choose 8400 8" CNC Tabletop Lathe System (LinuxCNC) if…
you want the lathe in its base configuration: an Ubuntu computer with LinuxCNC for 4-axis control, driver board and power supply already fitted, and only a monitor to add. You turn parts up to 200 mm between centers at a maximum of 2,800 rpm, with the tailstock still manual. What Package B contains is not part of this one.
Choose 8400B 8" CNC Tabletop Lathe System Package B (LinuxCNC) if…
Package B is the configuration you need: the lathe is the same, with the same LinuxCNC computer and the same utilities for converting CAD files or TrueType fonts to G-code. What the package adds over the base version should be checked on the manufacturer's page before ordering, because the mechanics do not change.
