Aluminum Oxide Precision Tool Grinding Wheel

Product Features:

This product is made from high-purity white aluminum oxide abrasive,which is hard and features sharp grains.During grinding,dulled grains are quickly shed,exposing new,sharp edges.This"self-sharpening"property ensures consistently high grinding efficiency.Its unique crystal structure aids in heat dissipation,minimizing adverse effects on the workpiece's metallurgical structure caused by heat buildup,thus preventing annealing or grinding cracks.The wheel has a uniform structure and excellent balance,ensuring smooth operation and resulting in high workpiece surface finish and dimensional accuracy,making it perfectly suited for precision-sensitive tool sharpening and tool manufacturing.

Product Specifications:

This product's outer diameter ranges from 100mm to 300mm,with common thicknesses of 10mm,13mm,20mm,and 25mm.The bore is typically 31.75mm or 50.8mm to fit standard tool grinders.The abrasive is Grade A White Aluminum Oxide.The grit size ranges from coarse 46#to fine 120#.The hardness grade is mostly K or L(medium-soft),providing a balance of moderate cutting force and good self-sharpening.The bond is a Vitrified bond,known for high strength and stability.The maximum safe operating peripheral speed is typically 60 m/s,complying with international safety standards.The wheel may be reinforced with fiberglass mesh for enhanced safety.

Product Applications:

Widely used in machine shops and tool manufacturing.Primarily used for sharpening and re-sharpening metal-cutting tools such as milling cutters,reamers,lathe tools,drill bits,and taps.It is also suitable for surface grinding,cylindrical grinding of precision parts,and fine polishing of mold cavities.When machining steels prone to burning,it outperforms standard brown aluminum oxide wheels,making it a reliable choice for ensuring the quality of high-value tools and components.
