Backplate fitting

Backplates are supplied machined to fit to the appropriate lathe spindle.

Backplate machining will be required on the other side to suit your particular application, which is a straightforward procedure:

• To ensure absolute accuracy, it is necessary to machine a suitable spigot on the backplate to match the register in the back of the chuck.
• Due to the various chuck PCDs, it is also necessary to drill and possibly tap the backplate to accept whichever chuck is being mounted.

Collet chucks

• Back plates are ideal for mounting a collet chuck to a lathe.

• Collet chucks available in ER 25, ER 32 or 5C size here.

WM 290V note

• There are two versions of the WM 290V lathe.
• The most recent model numbered 2900D has a D1-4 fitment, so this is the compatible backplate. This version of the lathe was sold from 2022 onwards.
• The previous version of the WM 290V was numbered 2900, this is not D1-4 - the backplate for that model can be found here.
