DEPRESSED CENTER WHEELS

Transcription

1 Norton Company s depressed center wheels are the industry s most advanced line of performance and value products for weld and flame cut grinding, pipe notching and steel and non-steel metal fabrication applications. TYPICAL INDUSTRIES AND APPLICATIONS Storage tank and general metal fabrication Petrochemical maintenance All weld grinding Shipbuilding Foundry notching and removing gates and risers Pipeline - root pass grinding, pipe bevelling and repair M6 NORZON THE ABSOLUTE FORCE WHEELS The world s two most advanced abrasives, NorZon (zirconia alumina) and Norton SG (seeded gel-ceramic aluminum oxide) have been combined to produce NORZON The Absolute Force. This patented performance product outperforms all wheels available today. These superior wheels let you cut faster and smoother all the way to the hub. NORZON The Absolute Force Depressed Center Wheels Patented combination of NorZon/Norton SG grain 50% better cut rate advantage over aluminum oxide Up to 9X the life of aluminum oxide and up to 2X the life of competitive zirconia alumina Excellent performance on all grinding jobs from gray iron to exotic alloys and stainless steel An advanced bond system Free cutting, easy on the operator and machinery Exceptional balance Minimal vibration; no workpiece bouncing Less operator fatigue Unique, patented mini mount for 4-1/2" wheels Up to 30% more wheel life because the hub covers just a small surface area, providing maximum grinding area exposure and usage 700% 500% Abrasive Life and Cut Rate Relative Performance Charts RELATIVE WHEEL LIFE CHART RELATIVE WHEEL CUT RATE CHART 200% 650% 165% 150% 300% 100% NORZON THE ABSOLUTE FORCE 360% COMPETITIVE ZIRCONIA 230% CHARGER 130% GEMINI 100% COMPETITIVE STANDARD ALUMINUM OXIDE 100% 50% NORZON THE ABSOLUTE FORCE 130% 120% 100% 100% COMPETITIVE ZIRCONIA CHARGER GEMINI COMPETITIVE STANDARD ALUMINUM OXIDE

3 GLOBAL WHEELS Quality Norton aluminum oxide wheels you can depend on for the results you need grinding alloys, steels and ferrous metals. Ideal where low initial cost is important. Global Depressed Center Wheels Manufactured to ANSI standards in Norton plants worldwide Resin bond Versatile Low initial cost per wheel Consistent quality, wheel-to-wheel Cool, free cutting Excellent results on stainless steels, alloys and ferrous metals Ideal for on-site and small unit jobs M8 AVOS TYPE 29 WHEELS AVOS - Allows View of Surface - Type 29 depressed center wheels join Norton Company's revolutionary system of products for right angle grinders that let you see the surface while grinding. These new, patented wheels produce superior surface finishes and complete work quicker - with more accuracy. AVOS Depressed Center Wheels - TYPE 29 Ideal for grinding / blending Innovative shape and patented slot design Provide complete vision of the grinding zone Operator can grind more accurately with less re-work Allow interrupted cut which reduces heat on workpiece Uniquely patterned face Cooler operating; prevents loading Type 29 shape - used at a 15-degree angle Shallow grinding angle permits larger contact area with less gouging of workpiece

4 BLENDING / FINISHING WHEELS GEMINI FLEXIBLE WHEELS These newly-formulated Gemini Flexible wheels are specifically designed for blending and finishing a wide variety of materials. Gemini Flexible Wheels Improved formulation Flexible Available in 36 grit Available in 60 grit Better blending, finishing and polishing of stainless steel, structural steel, cast iron welds and burrs Cool cutting; leaves no burn marks Meets nuclear industry standards Excellent control of finish quality and removal rate in light stock removal applications Ideal for light stock removal Designed for finishing applications COTTON FIBER BFR2 WHEELS The unique cotton fiber and abrasive blend found in BFR2 wheels make these some of the most versatile metal removal and finishing grinding wheels available. Cotton Fiber BFR2 Wheels Unique combination of cotton fibers, abrasive and flexible bond material Superior balance Available in 24 and 36 grit Very versatile; ideal for grinding and finishing bronze, aluminum and thin sheet metal Cushion-like action for uniform finishes No vibration or chatter marks 24 grit - ideal for light stock removal/blending Use 36 grit for finishing M9 Tech Tips For maximum performance, run the grinder at the highest possible speed marked on the wheel. Hold your right angle grinder at a: 90 angle with 1/16", 3/32".125" and 1/8" thick discs 30 angle with 1/8" and 1/4" thick grinding discs 15 angle with saucers and Type 29 wheels It is the user s responsibility to refer to and comply with ANSI B
