TIPS FOR USE
APPROACH POSITIONS EXACTLY:
With the ELS, it is very easy to move to a certain position: To do this, set the end position to the
desired value and then move manually with the travel keys < > << >> coming from the right. The
axis then stops at the end position, even if it is set to 0. This can also be extended if, for exam-
ple, you realize that it was not enough yet, you simply turn the end position further and drive
back there. By the way, you can cross the end position again by pressing the travel keys again!
SET THE ZERO POINT ON THE WORKPIECE SURFACE:
Setting the zero point correctly is essential for success. In order to hit the surface of a work-
piece very precisely, you can scratch the surface with the jog keys. To do this, you should select
the stepwise feed (with XSTEP/ZSTEP and the rotary knob) close to the workpiece and always
move from right to left and from the operator to the workpiece.
But if you have a few tenths of material left, it‘s easier and more accurate: You set the Z-axis
and X-axis so that they move a little bit into the material and set the axes there to 0. Then you
turn a length once with external turning, and then with face turning the face side. This gives you
the surface exactly on X0 and Z0, as well as two machined surfaces on which you can measure
exactly.
DRIVE FROM WAITING POSITION TO 0
After each function, the ELS sets the axes to the set waiting position. If this is not equal to 0, the
axes are at a value above 0. If you would like to move an axis to 0, set the end position to 0 and
move to it from the right. The axis then stops at 0. Pressing the move key again overruns the
point again.
PRECISE EXTERNAL TURNING MADE EASY
To rotate a shaft to an exact dimension, proceed as follows: Set the axes to 0 as described in
„Setting the zero point on the workpiece surface“. Then measure the outside diameter (prefer-
ably with a micrometer) of the machined end. To get to the nominal value you have to calculate
how much in radius you have to remove to get to the nominal value:
Example:
Measured value= 40,34mm
Set value= 34,00 mm
Dierence= 6,34 mm
Radius= 6,34/2 = 3,17mm <- Enter this value at „XP“!
You enter the calculated value as XP for external turning, so the X axis travels this distance in
several infeeds into the material. For ZP, enter the desired length and start the pass. At the end,
the diameter should correspond exactly to the desired value.
Tip: You can drive a last additional nishing run again by restarting the cycle and setting the
number of passes to 1.
