A variety of differently sized automotive camshafts can be supported for hardness testing by a new fixture from Indentec. For lubrication specialist Castrol, the carriage-style fixture accommodates anything from a short camshaft for a motor cycle to a multi-lobe shaft for a large car or small "commercial" engine. It enables cam lobes to be positioned accurately in sequence beneath the Rockwell test indenter, and provides full support while hardness tests are made along the length of the shaft. The camshaft is loaded between adjustable and spring-loaded centres on the carriage, which is slid along a guide rail to position each cam for testing. A self-aligning anvil on the test table compensates for any irregularities in the shaft surface as the test is carried out. The fixture is used on an Indentec digital Combined Rockwell testing machine with an eye-level touchscreen for control, display and monitoring. As each automatic test cycle is completed, the Rockwell or superficial Rockwell number and associated data are registered on the touchscreen and stored ready for downloading to computer in a format compatible with industry-standard PC spreadsheets, through one of the machine's two RS232 serial ports.
