A vertical rotary table is a precision device used in CNC machining or conventional milling machines to rotate a workpiece around a vertical axis. It allows the operator or CNC machine to perform complex operations like indexing, circular cutting, or machining at specific angles on a workpiece.
Here are the key points:
-
Orientation:
-
The axis of rotation is vertical (perpendicular to the machine table).
-
Workpieces are typically mounted on top of the table.
-
Purpose:
-
Enables rotational positioning of the workpiece for multi-angle machining.
-
Useful for operations like milling arcs, drilling evenly spaced holes, gear cutting, or creating circular patterns.
-
Types:
-
Manual Vertical Rotary Table: Operated with a hand crank or worm gear.
-
CNC Vertical Rotary Table: Motorized and controlled by the machine’s CNC system for precise positioning and automation.
-
Applications:
-
Drilling holes at precise angular intervals.
-
Machining circular slots or patterns.
-
Milling complex geometries requiring rotation around a vertical axis.
