The <strong>Hardinge</strong> style "AF" feed finger is versatile, adjusting quickly and easily to the tension you need. The style "AF" feed finger<br />
uses inexpensive pads which are readily available from stock. Each master feed finger includes a threaded locking cap which<br />
rotates to adjust in five- to seven-pound increments to increase or decrease tension. For thin-wall tubing and delicate stock,<br />
extremely light tension can be achieved.<br />
Because the style "AF" master feed finger can be adjusted to hold greater variations of bar stock sizes, you'll need to purchase<br />
fewer pads than with most other types of master feed fingers. Pads, which are sold separately and are required with each master,<br />
are held securely in place without screws. Guide bushings are sold separately and are recommended to minimize bar whip.<br />
The benefits of "AF" feed fingers include:<br />
Dependability. The feed bushings control bar whip to minimize feed "hang-ups" and allow a better finish on the part being<br />
machined.<br />
Versatility. A variety of inexpensive pads can be used to adjust to different bar stock diameters. A full 1 ⁄32" adjustment can be<br />
achieved from the rated size down. This eliminates the need for decimal/millimeter pads and pads in 1 ⁄64" increments.<br />
