Close-up shot of a diamond -pattern knurling on a cylindrical work piece. When someone requests DIAMOND knurl or wants to roll a DIAMOND PATTERN on a part, there are several questions that need to be answered. It is very easy to confuse what is required on the part and on the knurling die itself.
First we need to know whether a MALE (raised pyramid) or FEMALE (depressed pyramid) . Heavy Duty Style Straddle Square.
The circular pitch knurl system is the older system and has been in use many years. The spacing of the teeth is measured by the number of teeth per inch (TPI) around the circumference. Knurling Tools Technical Support. On diagonal and diamond knurls , the TPI is usually measured normal (or perpendicular) to the teeth. The video shows how diamond knurling can be done using a lathe machine.

The embossed patterns can be decorative, but more often act as hand grips and are commonly seen on handles, knobs or rollers. Diagonal, diamond andstraight are the three most common patterns generated by knurling dies. The circumference of the work blank should be an approximate multiple of the circular pitch for straight knurling and transverse circular pitch for diagonal and diamond knurling.
Blank diameters vary with the circular pitch of the knurling. Diagonal and diamond knurling on work blank may be accomplished by setting the axis of straight knurls at an angle to the work axis. When using straight knurls to produce diagonal and diamond knurling by end-feeding, the transverse diametral pitch that is produced on the work will not be the same as that of the knurl.
In most cases, a simple callout in a drawing is all that is needed for a machine shop to knurl your part. But if you want to go the extra mile, modeling the knurl in your 3D model is a nice touch and relatively easy to do. Our Advanced part modeling class will teach you the skills needed to model a knurl. Notice in this figure that when knurls are fully dimensioned on a drawing, there is no need to actually show them. The callouts for a knurl should include the type, pitch, and diameter.
The initials DP in the knurl. Mark Triton escribió en mensaje. Does anybody know how to create a 3D solid diamond knurl in AutoCAD? What is a diamond knurl ? Solved: Is there a command to apply knurling to a cylindrical surface ?
For gripping, both a properly roughed surface that ensures a good grip and appearance are important, and the diamond knurl typically is used. For applications where expanding function is key, then a straight knurl normally is machined. The relationship is the same whether the knurl is a diamond or a straight knurl.
How- ever, the spacing of the teeth of a diamond knurl must be measured along the axis of the part or roller for the relationship to hold true.
