Abstract
Disclosed is a scribing or engraving tool for use to mark, scribe or engrave using a a CNC, engraving or other automated machine. More particularly some examples of the invention include a coolant passageway for providing coolant to the stylus, and others provide a second spring which engages when desired for applying more pressure to the toolbit when desired. In yet another embodiment a coupling system may be used to provide for the rotation of the stylus holder and stylus to provide for engraving.
Claims15
A scribing tool holder comprising:
- a. a body which includes:
- i. a top end configured to be held by a rotational device;
- ii. a lower end that operably attaches to a stylus holder;
- b. a first spring which on a lower end operatively imposes a spring force on a stylus holder and on an upper end operatively interacts with a compression adjustment abutment, the first spring configured to impart a biasing force on the stylus when compressed by the compression adjustment abutment;
- and
- c. a flexure spring with a bias force higher than the biasing force imparted by the first spring, the flexure spring operatively interacts with the compression adjustment abutment on an upper end, and a lower end of the flexure spring is configured to operably interact with the stylus holder only when the adjustment abutment imposes a sufficiently higher compression biasing force to compress the first spring a distance to abut the flexure spring to the stylus holder.
