Indectec cuts set-up times for hubs

Keywords: Indentec, Hardness testing

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.

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, 50 mm 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.
