Norton 61463650291 Grinding Segment 36 Grit Aluminum Oxide

Product Description

The NORTON 61463650291 is a vitrified-bond surface grinding segment designed for heavy-stock removal on horizontal-spindle surface grinders. Manufactured from aluminum oxide abrasive at a 36 grit (very coarse) rating, this segment cuts aggressively on ferrous metals and hard toolroom materials. It measures 11-1/4 inches wide, 6 inches high, and 2-1/4 inches thick and weighs 12 pounds. The E hardness code and open grain structure (grade 12) allow the bond to release dull grains under load, maintaining a free-cutting action without excessive heat buildup. Specification code 86A36-E12VBEP identifies the full abrasive formulation. Licensed grinding technicians and toolroom machinists are the primary installers.

This segment is engineered for Cortland-application surface grinding operations, where large segmented wheel heads require a consistent, uniform abrasive block. The 36 grit designation makes it best suited for initial stock removal passes rather than finish grinding. The vitrified bond performs well in wet or dry grinding environments common in production and toolroom settings. At 11-1/4 inches wide, the segment covers a broad grinding path per pass, reducing cycle time on flat-surface operations. Blue Print reference ME30777 identifies the OEM specification for this geometry and abrasive combination.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous metals and hardened steels
• 36 grit (very coarse) for aggressive stock removal in roughing passes
• Vitrified bond construction allows use in both wet and dry grinding conditions
• E hardness code with open grain structure (grade 12) promotes free-cutting action and reduces heat
• Porous structure improves coolant penetration and swarf evacuation during wet grinding
• Blue Print ME30777 and spec code 86A36-E12VBEP for traceability to OEM grinding requirements

Compatibility

Designed for Cortland-application horizontal-spindle surface grinders requiring segments per Blue Print ME30777. Verify segmented wheel head geometry and clamping dimensions against the 11-1/4 x 6 x 2-1/4 inch block size before installation.

Installation Notes

Grinding segments must be installed by a qualified grinding machine operator or toolroom technician following the machine manufacturer's wheel-mounting procedures. Power down and lock out the grinder before removing or seating any segment. Inspect the segment for cracks or chips prior to mounting; never install a damaged abrasive block. Dress the segment face after installation and before first use to ensure flat, even contact across the grinding path.
