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 DP in knurling?

D.P. 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 1/2″ Diameter stock.

How do I specify knurling?

Knurling is specified in terms of type, pitch and diameter before and after knurling. Where control is not required, the diameter after knurling is omitted. Where only a portion of a feature required knurling, axial dimensioning is provided. ANSI/ASME B94.

What is a knurl pitch?

For knurls listed as a Metric Pitch, the pitch on straight knurls is the approximate tooth to tooth distance at the outside diameter of the work part measured in millimeters. For diagonal and diamond wheels, the Metric Pitch is measured perpendicular to the teeth or helix angle.

Can you knurl stainless steel?

When knurling stainless steels, it is important not to roll any longer than necessary as this material work hardens as it is formed. Then to knurl, move the holder so that the two wheels are as close to the centerline as possible to minimize the knurling pressure on work spindle and cross slide.

How do I check my knurling?

Divide the number of cutting teeth on the wheel by the blank circumference of the wheel in inches to find the number of teeth per inch (TPI). For example, if a wheel with a blank circumference of 6.28 inches has 157 teeth, it has 25 TPI. Divide 1.000 by the TPI of the knurl to calculate the knurl’s circular pitch.

What is standard knurling?

This International Standard covers knurling on workpieces with standardized diametral pitches. The knurling is made by displacement of the material on the surface of a workpiece when rotated under pressure against a knurling tool. The recommendations given are applicable for general purposes.
