Machining apparatus and method for machining a laminate

A method for machining a superficial portion of a laminate with a machine tool having a depth limiter that restricts a maximum machining depth of the machine tool, the method comprising:

• securing a guide frame over the superficial portion of the laminate, wherein the superficial portion of the laminate has a recess;
• providing a slide block which slides in a lockable manner along opposite, parallel first frame side and second frame side of the guide frame, a guide contour being configured to be displaceable with the slide block;
• inserting into the guide contour a probe tool which is shaped corresponding to the recess, the guide contour movably guiding the probe tool in a vertical direction and preventing the probe tool from moving relative to the guide contour in a horizontal direction;
• positioning the guide contour and the probe tool over the recess by moving the guide contour and probe tool relative to the guide frame in at least one direction parallel to the superficial portion;
• locking the probe tool in the recess once the guide contour and the probe tool are positioned over the recess;
• placing the machine tool within the guide contour in place of the locked probe tool, the machine tool being in contact with the superficial portion;
• and
• machining the superficial portion while guiding the machine tool by means of the guide contour.
