Value Collection SC09130063 Precision Sine Plate

Product Description

The VALUE COLLECTION SC09130063 is a precision sine plate used for accurate angular setups in machining and inspection work. This non-compound single-axis plate measures 6 inches wide and 2.5 inches high, with a roll centerline distance of 10 inches. Parallelism and squareness tolerances are both held to 0.0003 inches, making it suitable for high-accuracy workholding and layout tasks. At 37 pounds, the plate provides a stable, rigid base on surface plates, milling machine tables, and grinding fixtures. Machinists, tool-and-die makers, and quality technicians use this type of plate when angular positioning must meet tight tolerance requirements.

This sine plate is intended for use in machine shops, tool rooms, and metrology environments where repeatable angular setups are required. Typical applications include precision grinding, inspection fixturing, and layout work on ferrous or non-ferrous workpieces. The 10-inch roll centerline distance allows the plate to be set to specific angles using gage blocks in accordance with standard sine bar calculations. It is suited to both production and inspection environments where non-compound single-axis angular holding is sufficient.

Key Features

• Parallelism tolerance of 0.0003 inches for high-accuracy angular setups
• Squareness tolerance of 0.0003 inches ensures consistent reference alignment
• 10-inch roll centerline distance supports standard gage block sine calculations
• Non-compound single-axis design simplifies setup for single-plane angular work
• 37-pound mass provides a stable, vibration-resistant base during machining or inspection

Compatibility

Designed as an OEM-style precision workholding accessory suitable for use on standard surface plates, surface grinder tables, and milling machine tables that can accommodate a 6-inch-wide sine plate.

Installation Notes

Installation and setup of sine plates is typically performed by machinists or metrology technicians. Power down and lock out any machine tool before mounting or adjusting the sine plate on its table. Gage blocks used to set the desired angle should be wrung together and placed under the roll in a clean, burr-free condition. Verify the reference surface is clean and flat before seating the plate to maintain accuracy within the stated tolerances.
