J & S Model 1016 Brand New Knurling Tool Wt 3 Sets Knurls Straight Cutting Jaws Product Description Knurling has a wide variety of applications in day to day use. It is most commonly used for decorative purposes and for serrating surfaces where components are locked or keyed together in unit assemblies. Product Specification: Type of Knurling Tool: 3 Wheel Knurling Tools Overall length: 160 Approximate Weight: 720gms Approximate Application: The term "knurling" designates both the process and the knurled portion of the work. Knurling is obtained by displacement of the material when the knurl is pressed against the surface of a rotating work blank. A knurled tooth is "V" shaped. Knurling tools are used for producing STRAIGHT, DIAGONAL, OR DIAMOND patterns, having teeth of uniform pitch on cylindrical surfaces. Knurling and Pitch Systems: The CIRCULAR PITCH SYSTEM knurling is related to the distance between the teeth on the circumference of the work blank. It is usually expressed in terms of the number of teeth per inch (TPI), although sometimes erroneously referred to as Pitch. Speed and Feeds: For in-feed knurling, the knurl should be fed toward the work gradually until contact is made with the blank. This can be completed within 5 to 25 work revolutions. For end-feed knurling, the feeds used with the turret vary considerably and are dependent on the pitch of the knurl, the material, the diameter of the work blank, and the hardness being knurled. Two Ways to Achieve Knurling : (1) Forming Knurl forming is achieved by pushing the knurl wheels against the blank while rotating. This will cause the material to be displaced in cold form, reproducing the same wheel pattern on the blank circumference. The blank is increased accordingly to the T.P.I. The force applied through forming is increased in larger diameters making knurling difficult and slow. (2) Cutting Knurl cutting is achieved by using knurl wheels to actually cut instead of forming the blank. The knurl wheels are set at an angle, making the knurling edges of the knurl wheels cut into the blank. Pressure is minimized while speed and feed is increased. For Best Results: 1. Diameter of part being knurled should be turned to size for concentricity and quality of knurl. 2. Knurl wheels must be exactly in center line with the work-piece for an even knurl pattern. 3. Knurl wheels are to run freely and the knurl pin must be secured on the tool holder. 4. Use heavy flow of coolant to keep the knurl wheels cool and clean. 5. There is not an exact formula for knurling. Before starting production, follow the instructions and with trial and error the best results will be achieved.
