2. FEASIBLE KNURLING TYPE
The M10 form knurling tool is conceived for knurling on pieces with diameters between 8 and 200mm.
The obtained pattern depends on the knurls used knurls used as shown below.

3. SETTING THE TOOL AS RIGHT HAND OR LEFT-HAND
The M10 tool is conceived to work on right or left hand. To change
versions:
Remove the axle and the knurl.
Remove the spacer and its positioning pin.
Place the pin into the hole on the opposite face of the shank.
Place the spacer and re-assembly the knurl and the axle.
4. CLAMPING AND SETTING THE TOOL TO THE MACHINE
First, we need to make sure that the knurl rotates freely around the pin.
Spread graphite grease 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 ‘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
3.
5. 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.
6. 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 wheel gets in contact with
the workpiece.
Press the knurl against the workpiece. The value of the radial feed must
be according to the conditions recommended on the point 9. After that,
you will be able to feed longitudinally.
To calculate up to what diameter we must deepen with the knurl, we must
take into account the height of the tooth (in this case of standard knurls is
always equal to half the step) and the increase in diameter that suffer the
material.
That information is available at www.integi.com and in our catalogue.

7. BEFORE AND DURING THE WORKING PROCESS
Make sure that the knurl pins are firmly fastened.
Check that the knurl run free and lubricate it with graphite grease.
Always apply plenty of coolant, lubricant or cutting oil flowing in order to sweep the swarf away.
Always feed against the thickest of the areas that the hold the pin. If a second run is needed,
move the tool away from the workpiece and start again the knurling process. The working
direction, longitudinal advance, will always be against the tool.
8. 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 so that 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
