This catalogue describes the acme thread spindles and nutsavailable in our programme. Please contact us for informationon which sizes we have on stock.

Spindle production processCold-formed threading, more commonly called rolling, impliesthe cold forming of a metal bar by pressing during rotation withtools called dies, in order to obtain a thread or a knurling.

The process of rolling allows a high production speed and animportant saving in material as the diameter used is belownominal and unlike cutting it has no chips, thus no materialloss.

The mechanical properties improves up to 30% on hardnessand 12% on breaking strength, in fact the fibers of the materialare formed but not cut as in case of cutting. The roller finishingon the surface considerable increases the life time of thespindle or of the nut, improves fatigue strength and eliminatesthe starting points of fracture.

We are able to deliver in various materials such as specialsteels, stainless steel, brass and numerous alloys.

Produktionsprocessen for spindlerKoldformet gevindskring, ogs kaldet roulettering, sker vedkoldformning af en metalstang ved presning under rotationmed en gevindskrer, hvorved der dannes et gevind eller enriflet overflade.

Rouletteringsprocessen muliggr hj produktionshastighed ogen vigtig besparelse i materiale, idet den anvendte diameter erunder det nominelle ml, og i modstning til frsning er deringen spner og sledes intet materialespild.

De mekaniske egenskaber forbedres op til 30% p hrdhed og12% p brudstyrke. Faktisk formes materialets fibre, menskres ikke som ved frsning. Rouletteringen af overfladenforger skruens eller mtrikkens levetid betydelig, forbedrerudmattelsesstyrken og fjerner ansatser til brud.

Vi kan levere i forskellige materialer, f.eks. specialstl, rustfritstl, messing og diverse legeringer.
