A surface plate is a flat, precision-ground surface used for inspecting, measuring, and marking workpieces in machining and manufacturing processes. It is typically made of granite or cast iron and is used to ensure the flatness and accuracy of a workpiece.

An angle plate, on the other hand, is a tool used for holding and supporting workpieces at a specific angle for machining operations. It is typically made of cast iron or steel and has precision-ground surfaces to ensure accuracy. Angle plates are commonly used in milling, drilling, and grinding operations to hold workpieces at precise angles for machining.

In summary, the main difference between a surface plate and an angle plate is their primary function: a surface plate is used for measuring and inspecting flatness and accuracy, while an angle plate is used for holding workpieces at specific angles for machining operations.

Surface Plate:

- A precision ground, rectangular or round metal plate used for surface layout, inspection, and precision measuring.
- Provides a flat and accurate reference surface for measuring, scribing, and assembling components.
- Typically made of granite, cast iron, or steel.

Angle Plate:

- A rigid, L-shaped metal plate used to hold and position workpieces at precise angles relative to a surface plate or machine tool.
- Has one side at 90 degrees to the other, providing a vertical reference surface.
- Typically made of cast iron, steel, or aluminum.

Key Differences:

- Purpose: Surface plates are used as reference surfaces for measurement and layout, while angle plates are used for precise positioning of workpieces at angles.
- Shape: Surface plates are flat and rectangular or round, while angle plates are L-shaped.
- Precision: Surface plates have higher precision than angle plates, with a flatness and accuracy within thousandths of an inch. Angle plates typically have a precision of within a few thousandths of a degree.
- Uses: Surface plates are used in metrology, inspection, and precision manufacturing. Angle plates are used in machining, welding, and assembly operations.
