Re: AMADEUS Perforating System
By Craig Brougher
|Robert Hopp's terrific perforator system sounds ideal to me. The idea of a one-fingered Mot-zart zipping back and forth may sound a little "off-the-wall" until one looks at the way it is constructed. That thing should play until the cows come home! There is nothing like linear bearings for precision! Any lost motion caused by clearance or tolerance is divided by the number of balls contacting the shaft at any given time, and that happens to be dozens! So for all practical purposes, the lost motion is zero! And strength? Those things will support a tractor trailer! I have seen huge copy cameras weighing tons, whose copy platen is supported by just four of them, and whose overall precision is just a few thousandths of an inch in ten feet of travel. So that sounds like a good basic system, to me.
Also, he is apparently not relying on the wooden frame for alignment, but rather a steel "U" frame that contains all the punching mechanism. My one question about the software and operation of the machine is this: Does it punch from both directions (+ & - Y) or just one direction? Regardless of the answer, this sounds like a great machine.
