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.
