A platen for a metallographic grinder has an outer peripheral rim with an upper surface having a lower height. Also, fingers engaging a specimen are allowed to move laterally (i.e., wobble) to minimize the tipping forces on the specimen during the grinding process. Either one or both of these structures can be employed and results in a much flatter specimen surface for use in subsequent analysis.

Metallographic grinder and components thereof

An indentation hardness test system includes a frame including an attached indenter, a movable stage for receiving a part attached to the frame, a camera, a display, a processor and a memory subsystem. The camera captures images of the part, which can then be provided on the display. The processor is coupled to the movable stage, the camera and the display, as well as the memory subsystem. The memory subsystem stores executable code that instructs the processor to capture a series of real-time images of the part using the camera, obtain associated stage coordinates for each of the images and display a composite image, which includes the series of real-time images assembled according to the associated stage coordinates, of the part.

Indentation hardness test system

An indentation hardness test system includes a frame having a movable turret, a movable stage for receiving a part, a camera, a display, a processor and a memory subsystem. The turret includes an objective lens of a microscope and an indenter and the movable stage is configured for receiving the part to be tested. The camera captures images of the part through the microscope, which can then be provided on the display. The processor is coupled to the turret, the movable stage, the camera and the display, as well as the memory subsystem. The memory subsystem stores executable code that instructs the processor to capture and store a series of real-time images of the part using the camera, store associated stage coordinates provided by the stage for the images and display a composite image, which includes the series of real-time images assembled according to the associated stage coordinates, of the part.
