2. FEASIBLE PATTERNS
The M11 form knurling tool is conceived for knurling on pieces with diameters between 8 and 200mm.
The obtained pattern depends on the knurls used as shown below.

3. CLAMPING AND SETTING THE TOOL INTO THE MACHINE
First, we need to make sure that the knurl rotates freely around the pin.
Spread graphite if necessary.
Clamp the tool to the turret of the lathe.
While the chuck rotates very slowly, approach the tool to the workpiece until the
knurl makes contact with the workpiece.
Approach the knurling wheel to the workpiece following the ‘F’ direction up until
the teeth plunge a little into it. Check out the resulted print. The printed width (h)
must be equal to the width of the teeth on the knurl. If the width isn´t correct,
change the clearance angle.
The tool and the workpiece need to be aligned as shown on the drawing 2.
4. KNURLING STEPPED WORKPIECES
When knurling stepped workpieces, it is not possible to knurl up to a shoulder. Using this tool, no knurling
should be performed closer to 0,5mm from the shoulder itself.

5. BEGINNING TO KNURL
While the chuck is rotating at the speed recommended at point 8, feed the
tool so that 1/3 of the width of the knurling wheels gets in contact with the
workpiece.
Press the knurls against the workpiece. The value of the radial feed must
be according to the conditions recommended on the point 8. After that, you
will be able to feed longitudinally.
To calculate up to what diameter we must deepen with the knurls, we must
take into account the height of the tooth (in the case of standard knurls is
always equal to half the step) and the increase in diameter that suffers the
material.
That information is available at www.integi.com and in our catalog.
6. BEFORE AND DURING WORKING PROCESS
Make sure that the knurl pins are firmly fastened.
Check that the knurls run free and lubricate them with graphite grease.
Always apply plenty of coolant, lubricant or cutting oil.
The working direction, longitudinal advance, will always be against the tool.
7. TROUBLE SHOOTING
PROBLEM
CAUSE
SOLUTION
Double knurling
Too slow radial feed at the
beginning of the knurling
Increase radial feed at the beginning
of the knurling*
The perimeter of the workpiece is
not an exact multiple of the pitch
Turn a diameter that makes the
perimeter to be knurled is an exact
multiple of the pitch *
Knurling wheels easily
breakable
Knurling too deep
Reduce the depth to values according
to the pitch
Knurling wheels wear
out too fast
Knurling too deep
Reduce the depth to values according
to the pitch
Working conditions are not
adequate
Check cutting and traverse feeding
speeds
Table 3
*Sometimes, it is not possible to increase radial feed or it just cannot be radilly fed if the
workpiece is too weak.
