Instrument Description and Principle

This machine adopts an electromechanical integrated structure, consisting of a motor, reduction mechanism, specimen holder, abrasive hopper, and digital time controller.

It features low operating noise, high durability, and low power consumption.

The grinding wheel rotates at a constant speed. The specimen is pressed against the steel grinding wheel under a specified load using the applied weights. Abrasive material enters the grinding zone uniformly at a regulated flow rate, causing abrasion on the specimen surface and forming a wear groove.

The wear degree is determined by measuring the chord length of the wear groove on the specimen surface (accurate to 0.5 mm) and calculating the wear volume.

When using a wide grinding wheel, only the groove length is measured to evaluate abrasion resistance, without calculating volume.

Each specimen is evaluated based on the average wear volume from two different test positions.

Operation and Use

Select the grinding wheel and loading weights according to the test standard.Typically, the small weight and narrow grinding wheel are used.

Fill the hopper with dry abrasive material.

Fix the dry and clean specimen onto the specimen holder, ensuring that:

The specimen is perpendicular to the holder base

Its lower surface is tangent to the grinding wheel

Connect the power supply. The power indicator will light up.Perform a trial run.

Note: If the rotation direction is incorrect, interchange any two power wires.

Preset the test time (typically 2 minutes).

Lift the hook at the rear of the holder to bring the specimen into contact with the grinding wheel.Adjust the hopper gate so that abrasive material flows uniformly into the grinding zone.

Flow rate: greater than 1 L/min

Press the start button.The motor will run and automatically stop when the preset time is reached.

Then: Close the hopper gate,Stop the abrasive flow

Move the holder and remove the specimen.Using a measuring instrument with 0.1 mm accuracy, measure the chord length of the wear groove on the specimen.Perform measurements at two perpendicular positions on the specimen surface.

Use the measured chord length to: Find the corresponding wear volume from the reference table, or Calculate the volume using the provided formula.

Note: For a 70 mm wide grinding wheel, only the chord length is measured, and volume calculation is not required.
