Sine Plate

A Sine Plate is a precision tool used in machining and inspection processes. It is a flat plate with two accurately machined surfaces at a specific angle to each other, typically 45 degrees. The primary purpose of a Sine Plate is to provide a precise and repeatable method for setting up workpieces at specific angles for machining or inspection.

Sine Plates are commonly used in conjunction with other measuring tools, such as dial indicators or height gauges, to accurately measure and set angles. They are often used in applications where precise angular measurements are required, such as in the manufacturing of precision parts or in the inspection of machined components.

The two machined surfaces of a Sine Plate are used in combination with a sine bar or sine block to create a precise angle. By placing the workpiece on the Sine Plate and adjusting its position, the desired angle can be achieved. The accuracy of the angle is determined by the precision of the Sine Plate and the measuring tools used in conjunction with it.

Sine Plates are typically made from high-quality materials, such as hardened steel, to ensure durability and accuracy. They are available in various sizes and configurations to accommodate different workpiece sizes and applications.

In summary, a Sine Plate is a precision tool used in machining and inspection processes to accurately set up workpieces at specific angles. It is an essential tool in the field of precision manufacturing and is commonly used in conjunction with other measuring tools to ensure accurate and repeatable results.
