Norton 61463650304 Surface Grinding Segment 30 Grit

Product Description

The NORTON 61463650304 is a vitrified-bond aluminum oxide surface grinding segment designed for heavy-stock removal on rotary surface grinders. Measuring 11.25 inches wide, 8 inches high, and 3 inches thick, it weighs 12 pounds and carries a 30-grit, very coarse grade suited for aggressive material removal passes. The vitrified bond provides rigidity and porosity that aids coolant flow and swarf clearance during wet or dry grinding operations. Licensed grinding shops, tool-and-die professionals, and industrial maintenance machinists are the primary installers and operators of this segment.

This segment fits rotary surface grinder heads that accept large-format segments for flat-surface stock removal. The very coarse 30-grit specification makes it appropriate for initial breakdown passes on ferrous and non-ferrous workpieces where surface finish is secondary to material removal rate. The open grain structure (grade 12) supports free cutting and reduces loading on harder or tougher workpiece materials. The porous structure promotes coolant penetration, making the segment equally functional in wet-grinding environments common to production-floor applications.

Key Features

• Aluminum oxide abrasive for versatile grinding performance on ferrous and non-ferrous metals
• 30-grit very coarse grade for high material removal rates
• Vitrified bond maintains segment form and supports consistent cut geometry
• Porous structure aids coolant flow and reduces heat buildup at the grinding interface
• Grain structure grade 12 promotes free cutting and resists loading
• Large-format segment dimensions suit heavy-duty rotary surface grinder heads

Compatibility

Designed as an OEM-style replacement or direct-fit grinding segment for large rotary surface grinders that accept segments measuring 11.25 inches wide, 8 inches high, and 3 inches thick. Norton specification code 86A30-G12VBEP identifies the abrasive, grit, grade, grain structure, and bond for cross-reference purposes.

Installation Notes

Surface grinding segments are installed and dressed by qualified grinding machine operators or industrial maintenance machinists following the machine manufacturer's mounting procedures. Always inspect the segment for cracks or chips before mounting, and ensure the machine is fully de-energized and locked out before changing segments. Segment mounting torque and flanging requirements must follow the grinder manufacturer's specifications. Operators should perform a ring test and allow the wheel to run at operating speed for at least one minute before bringing the workpiece into contact.
