A Lock Down Jaw Machine Vice, also known as a "lock down" or "pull down" vice, is a precision clamping tool used in milling, drilling, and CNC machining operations. It securely holds workpieces in place, ensuring accuracy and stability during machining processes. The lock down mechanism minimizes jaw lift, enhancing clamping force and maintaining the workpiece's position even under heavy machining loads.

1. Lock Down Mechanism:

   • Equipped with a lock down or pull-down mechanism that prevents jaw lift when the vice is tightened.
   • This feature ensures that the workpiece remains firmly in place, improving machining accuracy and reducing vibrations.

2. Jaw Design:

   • Fixed and Movable Jaws: The fixed jaw remains stationary, while the movable jaw is adjustable to accommodate different workpiece sizes.
   • Hardened and Ground Jaws: Made from high-quality steel, the jaws are hardened and precision-ground to ensure durability and high clamping accuracy.
   • Replaceable Jaw Plates: Some models offer replaceable jaw plates for flexibility in handling different materials.

3. Body Construction:

   • Made from high-grade cast iron or steel, the body provides strength and stability.
   • Precision-machined surfaces ensure parallelism and perpendicularity, crucial for accurate machining.

4. Clamping Force:

   • Capable of exerting a high clamping force, often ranging from 1 ton to 3 tons, depending on the size and model.
   • Adjustable clamping pressure for delicate or heavy-duty operations.

5. Swivel Base (Optional):

   • Some models feature a swivel base, allowing the vice to rotate 360 degrees for angular machining and easy positioning.

6. Precision Ground Bed:

   • The bed of the vice is precision-ground, providing a smooth and accurate surface for the movable jaw to travel along, reducing wear and tear.

7. Alignment Features:

   • Side grooves or key slots allow for precise alignment on the machine table, ensuring consistent setup and reducing setup time.
