Gear Grinding Solutions by 3M


Gear Grinding | 3M Precision Grinding and Finishing

Grinding a gear to its final shape and finish requirements demands exceptional accuracy. Choosing the right gear grinding wheel is essential. That’s why 3M precision grinding experts consider the base alloy, tooth geometry and other key application factors when recommending a solution. Whether you need a wheel for continuous gear grinding, bevel gear grinding or single rib gear grinding, 3M has a custom grinding wheel designed to boost performance in your gear manufacturing process.

  • Continuous gear grinding application
    Threaded Gear Grinding

    Threaded grinding wheels enable continuous generation grinding, in which a number of motions occur simultaneously. The worm grinding wheel rotates on its axis while meshing with the gear workpiece which rotates on its axis. 3M™ Cubitron™ II threaded grinding wheels deliver the precision and performance required in the demanding gear manufacturing process.

  • Bevel gear grinding application
    Bevel Gear Grinding

    Along with worm wheels for continuous gear grinding, our product range includes solutions for discontinuous grinding processes, including:

    • Plunge grinding
    • Eccentric grinding
    • Gear profile grinding

  • Microscopic image of 3M Precision-Shaped Grain

    The Power of Precision-Shaped Grain

    For the highest conventional gear grinding performance, trust the long life and consistent cut of 3M Precision-Shaped Grain. This revolutionary abrasive technology powers 3M™ Cubitron™ II Bonded Gear Grinding Wheels. The uniformly sized triangles of ceramic aluminum oxide are designed to fracture as they wear, continually forming sharp points and edges that slice cleanly through the material.

    3M Precision-Shaped Grain gives our gear manufacturing customers a significant advantage in their grinding operations – with increases in material removal rates and reductions in grinding cycles and metallurgical damage compared to traditional ceramic gear grinding wheels.

    Learn about gear grinding wheel performance:

    Maximum material removal rate (Qmax) is a useful indicator when establishing performance parameters for a given machine model. Qmax refers to the chip volume in mm3 that can be removed in 1 second, and is calculated as follows:

    Qw max =
    (ae maxx hevx nss x gg x fz max)/COS β / 30

    hev: Ground profile height (mm)

    nss: RPM of worm wheel

    gg: Number of starts on grinding worm

    fz max: Max. axial feed rate per revolution of gear workpiece (mm/rev)

    cos β: Cosine of the helix angle of gear

    This formula will help establish your maximum removal rate. Keep in mind that it is important to consider other performance parameters like average chip thickness.
