Value Collection SC09130659 Precision Sine Plate 6x2 in

Product Description

The VALUE COLLECTION SC09130659 is a precision sine plate used for accurate angle setups in machining and inspection work. The plate measures 6 inches wide by 2 inches high, with a roll centerline distance of 5 inches. Parallelism and squareness are both held to 0.0002 inches, making this suitable for high-accuracy fixturing and layout tasks. It is a non-compound design, meaning it operates on a single axis of angular adjustment. Machinists and toolmakers use this type of plate in surface grinding, CMM setup, and precision inspection environments where angular positioning must be repeatable and verifiable.

This sine plate fits typical applications in machine shops, tool rooms, and quality control departments. Its 20-hole pattern supports clamping and workholding configurations across a range of part sizes. The non-compound configuration keeps setup straightforward for single-angle work. At 12.75 pounds, it is substantial enough to remain stable on a surface plate or magnetic chuck during use. Suitable for both production and inspection environments where angle accuracy is critical.

Key Features

• Parallelism tolerance of 0.0002 inches for high-accuracy angular work
• Squareness tolerance of 0.0002 inches ensures reliable perpendicular reference
• 5-inch roll centerline distance supports precise sine bar calculations
• Non-compound design for single-axis angular adjustment
• 20-hole pattern for versatile clamping and workholding
• Weighs 12.75 pounds for stable positioning on surface plates or magnetic chucks

Compatibility

Designed as a standard-format precision sine plate compatible with typical surface plate and magnetic chuck setups in machine shop and inspection environments.

Installation Notes

Sine plates are typically set up and used by machinists or metrology technicians. Before placing work on the plate, ensure the reference surface is clean and free of burrs or chips that could affect flatness. Use gauge blocks of known height with the roll centerline distance to calculate and set the desired angle. Do not exceed the plate's rated load capacity or apply side forces that could shift the roll pins during a grind or inspection operation.
