Norton 61463650287 Surface Grinding Segment 30 Grit

Product Description

The NORTON 61463650287 is a surface grinding segment engineered for heavy-stock removal on surface grinding machines. It is composed of aluminum oxide abrasive grain bonded in a vitrified bond matrix, producing a rigid, dimensionally stable segment suited to demanding wet or dry surface grinding operations. At 30 grit, this segment falls in the very coarse range, making it effective for aggressive stock removal rather than finish grinding. The hardness code F and grain structure 12 combine to deliver controlled breakdown of the abrasive grain as the segment wears. Specification code 86A30-F12VBEP captures all key parameters. Licensed grinding professionals and tool room operators handle installation and setup.

This segment is sized at 11.25 inches wide, 6 inches high, and 2.25 inches thick, fitting segmented-wheel surface grinder configurations that accept large-format segments. The Cortland application designation from the supplier data indicates a specific grinding machine or fixture family for which this segment is designed. Blueprint number ME30777 should be referenced when cross-checking fit on the target machine. This product is suited for industrial and commercial environments where high-volume material removal on ferrous or compatible workpiece materials is required.

Key Features

• Aluminum oxide abrasive provides durable, consistent cutting action on a wide range of ferrous materials
• 30 grit very coarse grade optimized for aggressive stock removal applications
• Vitrified bond offers rigidity and resistance to heat and coolant, maintaining segment shape under load
• Porous structure promotes coolant flow and chip clearance during grinding
• Hardness code F with grain structure 12 supports controlled, self-dressing wear behavior
• Blueprint ME30777 provides traceable dimensional reference for machine fit verification

Compatibility

This segment is designated for the Cortland application per supplier data, with blueprint number ME30777 used to confirm dimensional fit. Verify machine segment holder dimensions against the 11.25 inch width, 6 inch height, and 2.25 inch thickness before installation.

Installation Notes

Segmented grinding wheels must be installed and dressed by qualified personnel following the machine manufacturer guidelines and applicable ANSI B7.1 safety standards for abrasive wheel use. Power down and lock out the grinding machine before removing or mounting segments. Inspect each segment for cracks or chips before mounting — do not use a damaged segment. Perform a ring test where applicable and run the machine at operating speed without load for the recommended break-in period before engaging the workpiece.
