The Foundrax model BHD and BHD-E radial arm Brinell hardness testers offer the user a range of test head options.
These range from a simple machine using the Foundrax model 134 portable Brinell test head capable of indentation only and operating in a single Brinell hardness scale to a fully automatic machine incorporating the Foundrax ATH2 fully automatic Brinell test head with integral BRINtronic automatic Brinell microscope offering indentation and automatic optical measurement in scales from HBW 2.5/187.5 to HBW 10/3000.
The Foundrax Model BHD and BHD-E are heavy duty radial arm Brinell hardness testers specifically designed to handle the forces generated in Brinell hardness testing and not subject to the inherent weakness of machines which use converted radial arm drills or similar.
The machines consist of a Brinell Test Head for applying test forces up to 29 420N (3000kgf) and a heavy duty frame. The radial arm holds the Test Head of the machine and allows it to be manoeuvred to accurately position it for one or more tests without moving the workpiece. The arm can be moved out of the test area to allow the workpiece to be lowered onto the table by crane.
As with All ATH2 type machines, the BHD-E may be networked to allow automatic downloading of batch parameters etc as well as automatic uploading and saving of the test results and batch statistics.
The BHD and BHD-E have a maximum test height of 900mm and a maximum reach of 600mm. Other sizes can be specially made.
