Product Specifications

Technical details and manufacturing context for Grinding Wheel

Definition

A grinding wheel is a consumable abrasive component of a surface grinding machine that rotates at high speeds to remove material from workpieces through abrasive action. It consists of abrasive grains held together by a bonding material and is mounted on the machine's spindle. The wheel's primary function is to achieve precise dimensional accuracy, surface finish, and flatness on metallic and non-metallic materials during surface grinding operations. The wheel is available in various specifications, including diameters from 100 to 600 mm, thicknesses from 6 to 50 mm, and abrasive grain sizes from 16 to 120 mesh. The maximum operating speed ranges from 35 to 80 m/s, and the hardness grade is specified on an alphabetical scale from F to T. The maximum operating temperature is between 200 and 400 °C, depending on the bond type. Static balance quality is rated from G2.5 to G6.3, and radial runout is limited to 0.02 to 0.10 mm. The wheel can operate in environments with relative humidity up to 60–85% RH, and its weight ranges from 1 to 50 kg. Materials on file include aluminum oxide, silicon carbide, ceramic, cubic boron nitride, and diamond. These parameters are reference ranges and must be verified for the specific model and application. Standards such as ISO 603-1, ISO 6344-1, ISO 6103, ISO 525, and ISO 21940-11 are referenced for procurement and verification, but do not imply certification. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The grinding wheel rotates at high speed while making contact with the workpiece. Abrasive grains on the wheel's periphery cut microscopic chips from the workpiece material through a combination of cutting, plowing, and rubbing actions. Coolant is typically applied to dissipate heat, flush away swarf, and prevent wheel loading. The wheel's performance depends on the abrasive type, grain size, bond, and operating parameters. Proper selection of these factors ensures efficient material removal and surface finish. Regular inspection for cracks, wear, and imbalance is essential to prevent wheel burst. The maximum operating speed must never be exceeded, as this can cause catastrophic failure. The wheel's hardness grade and bond type determine its suitability for different materials and grinding conditions. Coolant flow and filtration are critical to maintain cutting efficiency and avoid thermal damage to the workpiece.

Frequently Asked Questions

What are the typical diameter and thickness ranges for a grinding wheel?

According to the directory, the wheel diameter ranges from 100 to 600 mm, and thickness from 6 to 50 mm, as per ISO 603-1. These are reference ranges; the exact dimensions depend on the specific machine and application. Always confirm with the manufacturer.

What abrasive materials are available for grinding wheels?

The directory lists aluminum oxide, silicon carbide, ceramic, cubic boron nitride, and diamond as abrasive materials. Each has different properties suited for various workpiece materials and grinding conditions. Selection should be based on the material being ground and the desired finish.

What is the maximum operating speed for a grinding wheel?

The maximum operating speed is listed as 35 to 80 m/s, per ISO 6103. Exceeding this speed can cause the wheel to burst, posing a serious safety risk. Always adhere to the speed rating marked on the wheel and verify with the manufacturer.

How should I verify the balance and runout of a grinding wheel?

Static balance quality is specified as G2.5 to G6.3 per ISO 21940-11, and radial runout is 0.02 to 0.10 mm per ISO 6103. These parameters should be checked before mounting the wheel. Use appropriate balancing equipment and dial indicators. Confirm the required values with the manufacturer for your application.
