Manufacturing custom threads and mechanical processing of highly customised special parts.
TÜV NORD CERT GmbH
We manufacture your ACME screw based on your individual design. ACME screws or Stub ACME threads are used to transform a rotational movement into a linear movement. ACME screws feature a flank angle of 29° and are mainly used in the US. The European couterpart is the trapezoidal thread according to DIN 103 with a similar flank angle of 30°. Both thread types are self-locking and therefore do not need to be secured separately in a resting position.
We manufacture:
The stub ACME thread is an ACME thread with a shallow thread depth. Stub ACME is a common thread used in down hole oil field completion equipment or in threading inserts.
We are capable to manufacture any ACME thread or ACME leadscrew design according to your individual requirements or according to any international standard.
We can machine ACME screws of up to 7,500 mm in one piece or even longer leadscrews if we combine multiple screw elements. Applying this method we already manufactured leadscrews in excess of 20 meters in length.
ACME power screws are used in different applications such as:
Additionally to the standard ACME power screw and matching nut, we are able to produce thread dimensions that go beyond the standard. Our leadscrews with the corresponding sets of lifting- and safety nuts include all the necessary turning, milling, and end machining operations, as well as surface and quenching treatments.
If you need an ACME screw with multi-start threads, this is also possible, with any number of starts your application requires. This differentiates us from other leadscrew manufacturers – we focus on your individual needs.
Here are the nominal dimensions for various thread profiles and the nominal dimensions for the metric ACME thread according to ANSI / ASME B1.5-1977. You will also find a sample technical drawing depicting one of our trapezoidal threads:
Just give us the specifications you want – that’s really all we need! As an ACME leadscrew manufacturer, we have specialized in the production of highly individual designs. You can leave the technical conversion of your vision into an actual finished product to us. Simply send us a technical drawing or rough sketch with some dimensions and we will do the rest.
