A Lathe Thru Chuck (also called a through-hole chuck or hollow chuck) is a special type of chuck used on a lathe machine that has a hole through its center, allowing long workpieces (such as rods, pipes, or shafts) to pass through the chuck and spindle.

What Makes It Different?

• Standard chucks grip the workpiece at one end, but a thru chuck allows the material to extend through the chuck and spindle bore.

• It's especially useful when working with bar stock or long shafts.

• Often used in CNC lathes, automatic bar feeders, or production setups.

Key Features:

A Dog Chuck with 4 jaws and double slots is a type of mechanical workholding device used in lathe machines to hold irregular or round workpieces securely while they rotate. It's designed to grip workpieces either symmetrically or asymmetrically, and the double-slot feature adds versatility for holding drive dogs or faceplate accessories.

🔩 Key Features: ✅ 1. Four Independent Jaws:

• Each jaw moves independently of the others.

• Ideal for holding irregular, square, or non-cylindrical workpieces.

• Allows for off-center turning and precise centering of odd-shaped objects.

✅ 2. Double Slot Faceplate:

• Two radial slots on the chuck face.

• These are used for clamping lathe dogs (which drive the workpiece when mounted between centers).

• Also allows mounting of custom fixtures or securing awkward shapes.

✅ 3. High Clamping Force:

• Independent jaws can be tightened individually for strong grip.

• Good for heavy-duty or rough machining.

✅ 4. Material and Construction:

• Usually made from hardened steel or cast iron for durability.

• Precision-machined for accuracy and reliability.

A 4-Jaw Independent Dog Chuck is a type of lathe chuck designed to hold irregular, non-cylindrical, or square workpieces securely for machining. Unlike self-centering chucks, each jaw in a 4-jaw independent chuck moves separately, allowing for precise manual centering of the workpiece.

It’s called a “dog chuck” because it can also be used with a lathe dog to drive the workpiece when mounted between centers.
