Specification

Description

Resin bond silicon carbide/aluminum oxide blend centerless grinding wheels are engineered for through-feed centerless applications where productivity, thermal control, and versatility are critical. By combining the sharp, free-cutting action of silicon carbide with the toughness and durability of aluminum oxide, these blended wheels provide a balanced grinding solution for operations running a variety of steels, cast irons, and non-ferrous materials. The resin bond system offers excellent shock resistance and controlled wear, making these wheels well-suited for demanding production environments where intermittent contact, part variation, or surface scale can challenge vitrified wheels. The result is a centerless wheel that cuts cooler, resists loading, and maintains consistent performance—helping improve throughput, reduce burn risk, and lower total cost per part in continuous through-feed grinding.

Features

  • Silicon Carbide / Aluminum Oxide Blended Grain System—This hybrid grain formulation delivers a unique balance: silicon carbide contributes sharpness and free cutting, while aluminum oxide supports durability and sustained performance on steels and ferrous alloys.
  • Resin Bond for Toughness and Shock Resistance—Resin bond construction provides excellent resistance to mechanical shock and helps maintain wheel integrity in high-throughput environments where parts may have interrupted contact, scale, or slight dimensional variation.
  • Cool Grinding Characteristics—The blend promotes efficient chip formation and reduced friction, lowering grinding temperatures and helping prevent thermal damage, discoloration, or part burn in continuous grinding.
  • Reduced Tendency to Load—Silicon carbide improves cutting behavior on gummy materials and non-ferrous metals, helping the wheel stay open and productive with less glazing.
  • Tunable Performance for Through-Feed Production—Wheel specification variables (grain ratio, grade, structure, and grit size) can be optimized to prioritize finish, cut rate, or wheel life depending on the part and stock removal requirements.

Application

Application

  • 1

    Through-feed grinding of mixed ferrous parts (mild steel and alloy steel pins, shafts, and dowels) where cooler cutting is needed.

  • 2

    Centerless grinding of cast iron components such as spacers, sleeves, and bushings requiring stable stock removal and finish.

  • 3

    Through-feed grinding of non-ferrous parts (aluminum, brass, bronze) where reduced loading and clean cutting are essential.

Recommendations

  • Use blend wheels when grinding mixed part families (steel, cast iron, and non-ferrous) to reduce wheel changeovers and simplify inventory.
  • Select grit and grade based on stock removal and finish needs—coarser for high removal, finer for improved surface finish and control.
  • Maintain consistent dressing practices to keep the wheel open and stabilize size control in through-feed operation.
  • Ensure proper coolant application to maximize thermal stability and support longer wheel life under continuous production conditions.
  • Avoid excessive pressure or feed changes; blend wheels perform best when grinding parameters remain stable and controlled.
