Hub hardness checked in one set-up
A fixture halves setting times by enabling both external and internal hardness tests to be made on drive shaft hubs without removing them from the test table.
A fixture from Indentec halves setting times by enabling both external and internal hardness tests to be made on drive shaft hubs without removing them from the test table Used on an Indentec digital Rockwell tester modified to give a long reach for internal testing, the fixture consists of a vee block module guided on the test table beneath a specially configured indenter nose

Stainless steel robotically hardness tested
Believed to be the first that a digital Vickers hardness testing machine has been adapted for robotic operation, a system has been configured for a Spanish stainless steel plant.
The drive shaft is secured in the vee by a screw down clamp, which grips the hub off centre.
This leaves the top of the hub clear for any number of hardness tests along the upper centreline.
Internal hardness tests are made in the hub bore with the hub still in the fixture.
The shape of the indenter nose permits testing deep inside the bore, 50mm and more.
Indentec says that the special fixture can accommodate a range of hub diameters.
To speed and simplify testing, the machine itself incorporates a touchscreen for selecting operational, monitoring and data processing functions.
An alpha numeric keypad enables component files to be pre-selected for the automatic setting of specific test parameters.
