Abstract
A visibility enhancement system for a CNC machine center that incorporates a windshield wiper assembly. The CNC machine center has a door with a window for viewing machining operations therein. The windshield wiper arm and its wiper blade are mounted on the inner surface of the window in the door. The windshield wiper assembly has structure on the outer surface of the door for reciprocally rotating the windshield wiper arm back and forth through a predetermined angle. The windshield wiper assembly has spring means for constantly pressing the wiper blade against the inner surface of the window. The windshield wiper arm has an adjustable length arm that allows different lengths of wiper blades to be used.

A method of installing a visibility enhancement system on a door window of a CNC machine center comprising the following steps:
- a) providing a CNC machine center having a door with a window for viewing machining operations therein;
- said door and window each having an outer surface and an inner surface;
- said window having a peripheral edge;
- b) providing a windshield wiper assembly having an elongated spindle housing, an elongated spindle, a spindle arm having a front end and a rear end, a windshield wiper arm and a wiper blade;
- said elongated spindle housing having a front end, a rear end, a diameter D1, a flange adjacent said front end and a bore hole extending from said front end through to said rear end;
- c) forming a hole in said door at a predetermined location adjacent said peripheral edge of said window;
- d) inserting said elongated spindle housing into said hole in said door from said outer surface of said door;
- e) fastening said flange of said elongated spindle housing to said outer surface of said door;
- f) inserting said rear end of said spindle through said bore of said elongated spindle housing;
- g) attaching said spindle arm on said rear end of said spindle so that said wiper blade is properly positioned on said inner surface of said window.
A combination structure of a CNC machine center and a windshield wiper assembly comprising:
- a CNC machine center having a door with a window for viewing machining operations therein;
- said door and window each having an outer surface and an inner surface;
- a windshield wiper assembly comprising a windshield wiper arm, a wiper blade, said wiper blade being properly positioned on said inner surface of said window, and means for reciprocally moving said windshield wiper arm back and forth to wipe a predetermined portion of said inner surface of said window;
- and
- means mounting said windshield wiper assembly on said door.
