einer Kupplung mit Kunststoffstern geht der Motor in seinen Schritten

minimal in "Voreilung", der Motor geht also in eine geforderte Position,

the case of a coupling with a plastic star, the motor minimally "leads"

components involved in the system (mainly also from the rigidity of the

the closer the cheeks come (while the width of the portal remains the

play of the guides or the distortion of the cheeks is more and more

portal delay does not only come from the guides, which should only be

and their connection to the portal.</span></font></span> <span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><font face="Arial"><span style="font-size:11pt;">Die

der Wangen nach hinten und vorne, was einer vertikalen Verdrehung des

table guides not only have a certain amount of play in the horizontal

inclination of the cheeks back and forth, which corresponds to a

vertical rotation of the portal.</span></font></span> <span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><font face="Arial"><span style="font-size:11pt;">Einfach

einen Portalbalken mit Winkeln an die Wangen anbinden ist nicht so

Verdrehkraft sicher nichts entgegen zu setzen haben).</span></font></span> <font face="Arial"><span style="font-size:11pt;">Simply
|

connecting a portal beam with angles to the cheeks is not so suitable
|

and only the twisting of such a connection is already great (the whole

force then goes through these thin angles, which certainly have nothing
|

to counter this twisting force).</span></font></span> <span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><font face="Arial"><span style="font-size:11pt;">Bei

Portalbalken verschweißt werden, da dort sehr hohe Kräfte auftreten.</span></font></span> <font face="Arial"><span style="font-size:11pt;">With a construction as in Figure 1, the cheeks should actually be welded to the portal beam, as very high forces occur there.</span></font></span> <span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><font face="Arial"><span style="font-size:11pt;">Darum

wird bei den EMS-Maschinen der Portalbalken überfräst und "stumpf" auf

die Wange aufgesetzt (pro Seite mit 8 Stück M8 Schrauben, das ist nicht

verschraubt, sondern "wie angeschweißt").</span></font></span> <font face="Arial"><span style="font-size:11pt;">That
|

|

is why the gantry beams on the EMS machines are milled over and placed

"bluntly" on the cheek (with 8 M8 screws per side, this is not screwed

on, but "as welded on").</span></font></span> <span class="notranslate" onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left"><font face="Arial"><span style="font-size:11pt;">Der Aufbau dieser Portal- oder Gantry-Bauweise wie in Bild 2 hat sich bei so kleinen und einfachen Fräsen schon fast etabliert.</span></font></span> <font face="Arial"><span style="font-size:11pt;">The

dieser Muttern defekt - stimmt leider nicht mehr. Leider waren in
|

|
|
letzter Zeit zwei Muttern defekt, aber diese wurden natürlich kostenlos

ersetzt. Noch wichtiger ist die Steigungsgenauigkeit der Spindeln, dort
|

|

kann man mit Chinaware echt Pech haben (darum messen Sie bitte die
|

|
|
Spindel nach!). Die NEFF-Spindeln werden von EMS nachgemessen und es

werden nur genaue Spindeln verbaut (absolut unterstes Ende von T7 -

a backlash> 0.05 mm will occur in China spindles after a while, you

have a backlash <0.02 mm with the NEFF spindles (even over a very

long time - for 8 years not even one of these nuts was defective - true

|
|
Unfortunately not anymore. Unfortunately two nuts have been broken
|
|||
|
|
lately, but of course they were replaced free of charge. Even more
|
|||
|
|
important is the pitch accuracy of the spindles, there you can be really
|

unlucky with chinaware (therefore please measure the spindle again!).

Spindles are measured by EMS and only exact spindles are installed
