Method and device for testing materials through penetration and separation resistance measurement uses a spindle stroke gearing mechanism with a spindle and a variable-speed motor drawing itself along the spindle.

摘要

A spindle stroke gearing mechanism (4) uses a spindle (6) and a variable-speed motor (1) drawing itself along the spindle by means of the gearing mechanism. On the front side the motor drives a drilling tool (5) like a drill bit using a drill chuck (3). The motor has an encoder (2) to monitor the duration of the number of its revolutions
