Lathe faceplate

A lathe faceplate is a circular, typically cast iron plate attached to the end of a lathe spindle, used to hold workpieces during turning. It can be secured using various methods: threads and cones, threaded studs with a recess, or camlock studs for rapid exchange. The faceplate allows attaching workpieces via t-slot nuts or threaded holes. Historically, it evolved into chucks but remains essential due to its flexibility and accuracy.

Faceplates come in types like dog plates (with slots for bolts) and slotted plates (accepting wedged holders). They are often customizable through drilling additional holes. Temporary faceplates made of wood or alloy can be used for specialized tasks, such as attaching thin materials for trepanning. Despite being considered primitive, faceplates remain crucial for their adaptability in holding diverse workpieces accurately.
