Product Testing Items and Data

No-load speed test: The speed of each machine is tested before leaving the factory. The 750W/900W/1200W models require 11000±500r/min, and the 850W model requires 12000±500r/min.

Withstand voltage insulation test: Apply 1500V/1min, leakage current ≤5mA, to ensure safe use.

Bearing noise test: When the whole machine is running, the noise of the bearing part is ≤85dB(A).

Drop test: The Black Warrior Series Angle Grinding Machine is dropped freely from a height of 1.5m onto a cement floor. The casing does not break, and the machine functions normally.

Carbon brush life test: After continuous operation for 100 hours, the wear of the carbon brush should be ≤ 1/3 of its original length.

Grinding wheel installation accuracy: Spindle runout ≤0.05mm to ensure smooth grinding.
