Guideline für das Gewindeschneiden
Gewindeteil in 5 einfachen Schritten:
|
Die Gewindetiefe verstehen: Alle unsere Gewinde werden mit einer Gewindeschneidmaschine CNC-gefräst und bei der Endkontrolle manuell geeicht. Das Gewindefräsen ist zuverlässiger als das manuelle Gewindeschneiden, für bessere Ergebnisse wird die Gewindetiefe auf etwa das 2,5-fache des Gewindedurchmessers eingestellt (siehe maximale Tiefe in der Tabelle unten). Es ist kein Problem, wenn Ihr Loch länger oder kürzer ist, denn unsere Software entwirft Ihr Gewinde wie folgt: |
SCHNELLDREHEN |
|
Sackloch <Ø×2.5Gewinde bis zum Ende (das letzte Gewinde endet etwa 0,25 mm vor dem Ende oder der Bohrerspitze). |
![]() |
Blind hole >Ø×2.5Der erste Teil des Lochs wird mit einem Gewinde versehen (bis zu einer Tiefe von etwa Ø×2,5) |
![]() |
Through hole <Ø×2.5Vollständig gewindet |
![]() |
Through hole >Ø×2.5Wenn beide Seiten zugänglich sind, können Sie bei der Gewindeauswahl eine der beiden Seiten oder beide Seiten auswählen. Wenn Sie beide auswählen, sind die Gewinde jeweils etwas weniger als ½ der Tiefe des Lochs: Sie treffen sich nicht in der Mitte. |
![]() |
Through hole >Ø×5Bei längeren Löchern werden die Gewinde bis zur maximal möglichen Tiefe geschnitten. |

Tipp zur Erhöhung der GesamtgewindetiefeDurch Hinzufügen einer Senkbohrung kann das Gewindewerkzeug weiter reichen. Eine Senkung ist auch ein großartiges Design for Assembly (DfA) Merkmal. |

Coil and key inserts
Spuleneinsätze (HELICOIL®) und Keileinsätze können ein haltbareres Gewinde in weicheren Materialien liefern. Wir können einsatzbereite Gewinde bearbeiten. Diese können Sie über unser interaktives Angebot auswählen.
Wir liefern und montieren auch eine Reihe von metrischen HELICOIL® Standardeinsätzen mit einer Gewindelänge von 1 × Gewindedurchmesser (D), 1,5D und 2D. Wenn Sie montierte Einsätze benötigen, teilen Sie uns dies über die Schaltfläche "Spezielle Anweisungen" in Ihrem Angebot mit; geben Sie dabei bitte die Länge und die Position des Einsatzes an.
Weitere Überlegungen:
Gelegentlich behindern Teilemerkmale oder Vorrichtungen die Gewindewerkzeuge. Wenn ein Loch nicht mit einem Gewinde versehen werden kann, zeigen wir dies durch Weglassen des Gewindes im interaktiven Angebot an.
Bei Gewinden auf Drehteilen wird einfach der Nenndurchmesser modelliert; die Gewinde müssen nicht modelliert werden.
Unser standardisierter Werkzeugsatz ermöglicht eine unglaublich schnelle CNC-Fertigung (so schnell wie am selben Tag). Das bedeutet jedoch auch, dass wir nur die aufgeführten Gewinde liefern können, Linksgewinde, nicht aufgeführte Durchmesser oder Steigungen sind derzeit nicht möglich.
Wir können nur modellierte Gewinde größer als M12 oder UNC ½"-13 (½" Unified Course by 13 Thread Per Inch (TPI)) oder größer unterstützen - sie werden mit einem Kugelfräser gefräst.
Wir können keine .SLT-Dateiformate unterstützen
Was ist die minimale Gewindetiefe? Unsere Software erkennt Gewindelöcher, die eine Tiefe von mindestens 1,5 x Gewindesteigung haben.
Was ist die empfohlene Mindestgewindetiefe? Die empfohlene Mindesttiefe für ein starkes Gewinde ist 1 x Durchmesser für Stähle und Hartmetalle, 2 x Durchmesser für Aluminiumlegierungen und weiche Metalle und so tief wie möglich für Kunststoffe: 2,5 x Ø (ein HELICOIL®-Einsatz wird empfohlen, um die Festigkeit und Haltbarkeit des Gewindes in weichen Materialien weiter zu erhöhen).

The Minimum Ø and Maximum Ø are the limits our software uses to recognise holes that can be threaded
The maximum thread depth is the limit of our thread cutting tools, starting from the hole face selected, excluding any chamfers of counter bores. Your hole should be deeper than this depth to allow for swarf. Even if you model a deeper hole, only the first portion will be threaded.

Coil inserts are not supplied, as standard.
We can supply and fit helicoils to all threads marked #, please request when quoting using the special instructions textbox.

Outside diameter special threads
External threads can be milled, this normally only works well for larger threads, as these will be milled using a ball end cutter (M4 is the absolute minimum, but ideally M12 and above). Your thread will have radii in the root, so might need cleaning up with a die. We can mill most custom threads or helical forms that you can model – on the lathe, 5-axis mill or 3-axis. External 3-axis milled threads are produced on the half diameter. The part is then rotated 180 degrees, re-referenced, and the other half milled.
On parts that require externally milled threads, you must design the threads on your part. We manufacture your design using flat and ball end mills. It is not the preferred method for producing threads, but can be useful for producing ¼ turn fasteners or helical and camming features.
The CAD file should then be submitted in a 3D file format other than STL; we accept most native CAD formats or a standard file formats such as IGES or STEP are also great.
Note: for standard threads only model the drill or outside diameter, we are unable to manufacture standard threads that have been modelled.
