Value Collection SC09130113 Compound Precision Sine Plate

Product Description

The VALUE COLLECTION SC09130113 is a compound precision sine plate designed for high-accuracy angular setups in machining, inspection, and toolroom environments. Measuring 6 inches wide and 3-1/4 inches high, this sine plate holds parallelism and squareness tolerances of 0.0002 inches, making it suitable for precision layout and grinding operations where angular accuracy is critical. The compound design allows for two-axis tilt, enabling complex angle setups without repositioning the workpiece. Machinists, toolmakers, and quality control technicians are the primary users of this type of equipment.

This compound sine plate is used in toolrooms, machine shops, and inspection departments for setting precise angles on surface grinders, optical comparators, and CMM setups. It is well suited for both production and prototype work where repeatable angular positioning is required. The 0.2-inch minute angle step specification supports fine angular adjustments across a wide range of setups. Applications include fixture building, jig grinding, and precision part inspection.

Key Features

• Compound design allows simultaneous two-axis angular adjustment for complex setups
• Parallelism tolerance of 0.0002 inches for high-accuracy work holding
• Squareness tolerance of 0.0002 inches ensures reliable angular reference
• 6-inch wide working surface accommodates a range of part sizes
• 0.2-inch minute angle step supports fine, repeatable angular increments
• Weighs 27 pounds, providing stable mass for vibration resistance during grinding operations

Compatibility

Designed as a general-purpose compound precision sine plate compatible with standard surface grinder tables, inspection surface plates, and toolroom fixtures that accept magnetic or mechanical workholding accessories.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician familiar with precision angle plate equipment. Ensure the mounting surface is clean and free of burrs or debris before placing the sine plate to maintain accuracy. Use precision gauge blocks of appropriate size to set the desired angle according to standard sine bar calculations. Avoid exceeding the rated load capacity and handle with care to protect precision-ground surfaces from nicks or corrosion.
