Abstract: A method of calibrating a component having first and second opposite large surfaces and a peripheral surface which interconnects the large surfaces and which is provided with a recess, includes the steps of placing the component in a calibrating die, thereafter introducing a calibrating slide into the recess, contacting the first large surface by a first die punch and contacting the second large surface by a second die punch for positively positioning the component in the calibrating die by the calibrating slide and the first and second die punches, and then applying a calibrating pressure to the opposite large surfaces of the component by the die punches for deforming the component to effect calibration of the recess to desired dimensions as determined by a thickness of the calibrating slide situated in the recess.
