What is a 96 DP knurl?
What is a 96 DP knurl?
American Standard ANSI B94. 6-1984 describes the diametral pitch knurl system. The number of teeth that will be rolled can be easily determined by multiplying the blank diameter by the Diametral Pitch of the knurl. Example: A 96 D.P. knurl will roll 96 x 1/2 = 48 teeth on a 1/2″ diameter stock.
What is Diamond knurling?
Knurling is obtained by displacement of the material when the knurl is pressed against the surface of a rotating work blank. Knurling tools are used for producing straight, diagonal or diamond patterns, having teeth of uniform pitch on cylindrical surfaces.
How is knurl pitch calculated?
Count the number of gaps between lines and divide by the distance between them and you’ll have the circular pitch, which is used in the form below.
How deep should a knurl be?
How “deep” to knurl? A fine knurl is 0.010-0.015 inch, a medium knurl 0.015-0.025, and a coarse knurl 0.025-0.035. Whatever depth you are knurling to, the procedure is to go all in. In other words, you move the cross slide or adjust the squeeze (scissor-type knurler) to the full depth, right from the initial contact.
What is a knurl used for?
It is mainly used on small-diameter bolts. Knurled nuts are typically used in electrical components, musical instruments and in automobiles. Aside from adding functionality to an object (valve repairs and hand grips being some of the most common), knurling also adds a decorative pattern to the material.
Is standard for knurling?
This International Standard specifies a series of knurling dimensions intended for general use in mechanical engineering and is intended to avoid an unnecessary multiplicity of tools by restricting the profile angle to 90° and by restricting the selection of diametral pitches.
How do you make a Knurl?
Tutorial – Creating knurl in SolidWorks?
- Start SolidWorks in Part mode.
- Top Plane>>Sketch.
- Draw a circle of 70mm diameter.
- Extrude it by 100mm.
- Select chamfer tool.
- Select both edge and chamfer it by 5mm at 45º.
- Select the bottom face and then sketch.
- Select the outer edge and then convert entity.
