Additionally, the wheel’s balance and runout tolerances are vital for high-speed operations to prevent vibration and ensure cut quality. Buyers should request detailed technical drawings or CAD files to confirm these dimensions before placing orders, especially for custom or non-standard sizes.

Surface properties and coating characteristics significantly influence the tool’s performance and lifespan. Observed data indicates coating thicknesses ranging from 0.20 to 1.5mm for single-side applications after grinding, with hardness values reaching Hv1300. These metrics suggest the use of advanced coating technologies, such as detonation spraying, which can provide superior wear resistance compared to standard plating. Surface roughness is typically specified around 0.4, indicating a fine polish that may be beneficial for smooth operation. Buyers should verify the surface bonding strength, with observed values exceeding 10kg/M, to ensure the coating will not delaminate under operational stress. Understanding these technical parameters allows for better prediction of tool life and maintenance intervals.
