    Study Notes

    Holding Devices

    • Holding tools, also known as work-holding devices, are used to hold components in bench work.
    • Common devices include vises with fixed and movable jaws.
    • Choose a vise appropriate for the strength required for the work.
    • Wear safety glasses or goggles, or a face shield when using tools or machinery on items held by a vise.
    • Securely attach the vise to the workbench.
    • Position workpieces close to the vise jaws to prevent vibrations.
    • Support long workpieces using saw horses or other supports.
    • Keep mechanical parts lubricated and free of debris.

    Bench Vises

    • Bench vises are a common work-holding device.
    • They are mounted firmly to a workbench using nuts and bolts.
    • Vises typically have a fixed jaw and a movable jaw.
    • The movable jaw is adjusted using a handle.
    • The jaws are used to hold workpieces.

    Pipe Vises

    • Pipe vises resemble bench vises.
    • Pipe vises are designed for holding cylindrical components.
    • Their shape accommodates the curvature of existing components.
    • Workpieces can be securely clamped between the jaws.

    Toolmaker's Vises

    • Toolmaker's vise is used when a strong clamping force is needed.
    • Fixed jaw and movable jaw.
    • Movable jaw is tightened by a screw.
    • Made from hardened alloy steel.
    • Jaw surfaces are precisely ground, square, and parallel.

    Hand Vises

    • Hand vises are designed to hold work pieces between its jaws.
    • The wingnut tightens the vise in one direction.
    • The wingnut loosens the vise in the other direction.

    Safety Precautions

    • Inspect tools before use for any damage.
    • Ensure a secure grip on tools to prevent slippage.
    • Maintain good posture and balance while working.
    • Use appropriate personal protective equipment (PPE).
    • Follow instructions on tool operation for added safety measures.
