3. What is Bench Vice A bench vice is a type of vise that is used to hold an object in place while it is being worked on.  Most bench vises are bolted to a workbench, and they stay stable while the work is being done. Bench vises are adjustable and allow you to change the amount of pressure exerted on the item you are working with. Bench vises are common in mechanical workshops, machine shops, woodworking shops, and metalworking shops.

6. Components and Functions Fixed Jaw The "fixed jaw" (a type of jaw) is one of the surfaces on which a workpiece wedges during clamping to hold it in place. It is not movable to provide stability and strength to the clamp.

7. Movable jaw The "movable jaw" is the second surface of contact of the vise with the workpiece . It is a part that can move when the vise is tightened with the screw or handle to press the workpiece against the fixed jaw and immobilize it.

8. A clamping surface In order for a vise to remain in place when clamping a workpiece , it must be clamped to a larger or heavier surface to ensure a good clamping force and hold. A clamping surface is therefore provided for this purpose.

9. Main Screw The main screw is one of the most important parts of the bench vice. When pressure is applied to the handle, then it is converted into the movement of the sliding jaw that moves toward the static jaw. The main screw is vital if it is not manufactured then the vice will not be able to hold objects well.

10. HANDLE The handle of an Apex bench vice is a crucial part of the tool’s mechanism, enabling the user to apply torque to the lead screw, which in turn moves the sliding jaw to grip or release a workpiece . It is designed for ease of use and durability, allowing for efficient operation of the vice.

11. Screw The most common uses of screws are to hold objects together. Screws might be inserted into holes to hold the vice with the table. Round Headed Machine screw Sq.15x2Counter sunk screw Sq.10x2

13. Assembly and Dismantling Process 5. Dismantle the Base: Finally, unbolt the base from the workbench. 6. Cleaning and Storage: Clean all parts using a cloth and apply lubricant to prevent rust. Store all components in a dry place. 7. Safety Precautions Always wear safety gloves to protect your hands. Use proper lifting techniques when handling heavy components. Ensure that the vice is properly secured to the workbench to avoid accidents. Apply appropriate force when tightening bolts to avoid stripping threads. Dismantling 1. Remove Jaw Plates: Unscrew and remove the jaw plates using the appropriate screwdriver. 2. Disassemble the Movable Jaw: Loosen and remove the guide rods. Unscrew the lead screw and pull out the movable jaw. 3 . Remove the Lead Screw: Once the movable jaw is removed, unscrew and pull out the lead screw from the fixed jaw. 4. Detach the Fixed Jaw: Unbolt the fixed jaw from the base. 5. Dismantle the Base: Finally, unbolt the base from the workbench.

14. 5. Attaching the Movable Jaw: Slide the movable jaw onto the lead screw and attach the guide rods to ensure proper alignment. 6. Securing Jaw Plates: Attach the jaw plates to both the fixed and movable jaws using screws or bolts. Tighten the screws to ensure a secure grip on the workpiece . 7. Final Adjustments: Ensure that the movable jaw moves smoothly by turning the handle. Apply lubricant to the moving parts to reduce friction. Assembly 1.Preparation: Ensure all parts are clean and free from debris. Gather the necessary tools for the assembly process. 2. Mounting the Base: Place the base on a solid workbench. Align the holes in the base with the workbench and secure it with bolts using a wrench. 3. Installing the Fixed Jaw: Attach the fixed jaw to the base using bolts and secure them tightly. 4. Installing the Lead Screw: Insert the lead screw through the fixed jaw’s screw hole and secure it to the handle.
