Norton 61463604490 Surface Grinding Segment 30 Grit

Product Description

The NORTON 61463604490 is a vitrified ceramic surface grinding segment designed for use on rotary surface grinders in industrial and production grinding applications. The segment measures 5 inches wide, 6 inches high, and 1-1/2 inches thick. It is bonded with a vitrified bond and features an open, porous grain structure rated at structure 12, which promotes chip clearance and reduces heat buildup during heavy stock removal. At 30 grit with a G hardness rating, this segment is classified as very coarse and is suited for aggressive material removal passes rather than fine finishing work.

This segment is intended for use on horizontal-spindle, reciprocating or rotary surface grinders commonly found in production shops and tool rooms. It is listed for use on Hanchett, Mattison, and Norton grinding machines, making it a direct fit for those platforms. The ceramic abrasive grain is engineered to fracture and self-sharpen during operation, sustaining cutting efficiency through extended grinding cycles. This type of segment is typically installed in sets of multiple units to complete a full grinding wheel assembly on segmented-wheel machines.

Key Features

• Ceramic abrasive grain with self-sharpening fracture characteristics for sustained cut rate
• 30 grit, very coarse grade — optimized for high stock removal applications
• G hardness code, indicating a relatively soft bond that releases dull grains readily
• Vitrified bond provides rigidity, porosity, and resistance to heat and coolant
• Open grain structure (structure 12) aids chip clearance and reduces grinding heat
• Compatible with Hanchett, Mattison, and Norton surface grinder platforms per blueprint ME20579

Compatibility

Listed for use on Hanchett, Mattison, and Norton surface grinding machines per Blue Print Number ME20579. Consult machine specifications and segment mounting requirements before installation. This product ships in a minimum order quantity of 8 units.

Installation Notes

Surface grinding segments must be installed by qualified personnel following the grinder manufacturer's mounting and balancing procedures. Always de-energize and lock out the grinding machine before removing or installing segments. Inspect each segment for cracks or chips before mounting — never install a damaged segment. Segments must be properly seated and torqued in accordance with machine manufacturer specifications, and the assembled wheel should be dressed before first use.
