Technical Specifications
The test specimen is clamped with an holder and submitted to a test force of 294 +/-3 N. After the abrasive is strew on the disc, the disc starts to rotate with a constant speed for a certain number of cycles. The disc abrader conforming to Bohme method consists of a rotating wheel made of cast iron, 750 mm dia., with a defined test track to receive the abrasive material (white corundum sand) and a no-vibration specimen holder with a two arms lever loading device. At the end of the test the abrasion effect is measured as the loss in specimen thickness or volume.
The measuring device, basically a 0.01mm resolution dial gauge mounted on a reference base, allows to measure the sample thickness in 9 points as defined as alternative abrasion measurement method. Volumetric method is valid for all the standards.
The machine is equipped with a display control panel that allows the setting of speed and number of cycles. Once the machine is started, it will automatically stop at the end of the set number of cycles programmed on the control panel.
