What is Indexing chuck?
An indexing chuck is a special type of workholding device used on lathes, milling machines, and grinding machines. It allows you to rotate the workpiece to precise angular positions (e.g., 30°, 45°, 60°, 90°) without removing it from the chuck.
In simple terms:
- A regular chuck holds the workpiece and spins it continuously.
- An indexing chuck holds the workpiece and can lock it at specific angles so you can machine different faces or features accurately.
Common uses:
- Cutting gear teeth
- Drilling holes spaced evenly around a part
- Milling flats or slots at exact positions
How it works:
The chuck has a built-in indexing mechanism (like a dividing plate or a lock pin) that lets you rotate the workpiece in fixed steps. Once you turn it to the desired position, you lock it in place and perform the machining operation.
