Constructing strong combination cylinder lock - using laser beam boring machine to form all opening cylinders in double rows in point and plane-symmetrical arrangement

摘要

Lateral drill holes are effected to the right and to the left on the main cylinder, and can be independently selected the ones from the others. By fixation of a point symmetrical centre in the key bit, the points to accommodate the opening cylinder are located point-symmetrically from the top and the bottom, so that a doubled power of the multiplicative combination enters into force. A laser cannon drilling device is used initially, and is then replaced by a simple drilling machine with automatic probing facility, whereby the key bit (C) can be inserted and drilled or can be directly parallel-produced, with subsequent marking via computer-controlled space points achieved by a laser beam (23-28) fixed to a robot being used. USE/ADVANTAGE - To produce safety cylinder lock with more than 1.4 thousand million combination possibilities.
