Norton 61463650289 Surface Grinding Segment 30 Grit

Product Description

The NORTON 61463650289 is a vitrified bond surface grinding segment designed for heavy-stock removal on industrial surface grinding equipment. Measuring 11.25 inches wide, 6 inches high, and 2.25 inches thick, this segment uses aluminum oxide abrasive at a very coarse 30 grit rating. The hardness code G designation and grain structure 12 indicate a relatively soft, open wheel that releases abrasive grains efficiently under load. At 12 pounds, this is a substantial segment suited for large reciprocating surface grinders operated by trained grinding machine operators in industrial and manufacturing environments.

This grinding segment is specified for the Cortland application and carries blueprint number ME30777 with specification code 86A30-G12VBEP. It is intended for use in production grinding operations where aggressive material removal rates are required. The porous structure promotes coolant flow and chip clearance, reducing heat buildup during extended grinding passes. Industrial grinding technicians and machine operators working in job shops, tool rooms, and production facilities are the primary installers and users of this segment.

Key Features

• Aluminum oxide abrasive with 30 grit for very coarse, high-removal-rate grinding
• Vitrified bond construction provides rigidity and consistent performance under load
• Porous grain structure promotes coolant flow and reduces thermal buildup
• Hardness code G for efficient grain release and reduced glazing
• Blueprint number ME30777 allows direct OEM cross-reference for replacement orders
• Full specification code 86A30-G12VBEP for precise identification

Compatibility

Specified for the Cortland application per blueprint ME30777. Designed as a replacement or production segment for large reciprocating surface grinders accepting segments of 11.25 inches wide by 6 inches high by 2.25 inches thick.

Installation Notes

Surface grinding segments must be installed by qualified grinding machine operators following the machine manufacturer's mounting and clamping specifications. Always power down and lock out the grinder before removing or seating a segment. Inspect the segment for cracks or chips before installation and perform a ring test where applicable. Follow applicable ANSI B7 grinding wheel safety standards during handling, mounting, and operation.
