ABSTRACT:
A method for forming an electrostatic field deflector tube (50) for use in an electron beam machine (10) which comprises the use of a rigid boring bar (88) with a diamond scribe tip (90) and a rigid holder (92) for the metal coated tube. The scribe tip (90) is positioned within the bore of the tube and the boring bar (88) is stroked in a direction parallel to the tube axis while engagement with the inner coating to scribe very narrow lines (66) on the inner surface of the tube. These lines (66) are formed over a major portion of the length of the tube and of a width less than 0.001 in. After each scribing step, the tube (or the boring bar and scribe tip as the case may be) is incrementally rotated to form a number of separate electrically isolated areas. Dial position indicators with digital readouts (92) locate the scribe tip (90) within a few ten thousandths of an inch and optical and resiatance means are used to determine the integrity of each scribed line.
