Drejebænk drejning præcision kobber elektriske dele

Billedet til venstre viser en kobberdrejedel med indvendigt og udvendigt gevind. Vente, noget virker galt. . . . . . Er dette kobber?
Det er rigtigt, dette er en kobberdrejet del, lavet af C3604 hurtigskærende messing, overfladen er galvaniseret, og pletteringen er forniklet, så det ligner rustfrit stål.
Dette produkt har både indvendigt gevind og udvendigt gevind, indvendigt gevind er M4, udvendigt gevind er M6. Mens den ydre gevindskårne øvre fladsidet fræsning, og tråd for at sikre 100% overholdelse.
Hvordan drejer vi sådanne indvendige og udvendige gevindprodukter? Du kan henvise til denne adresse, det første produkt på denne side er det halvfabrikata af produktet til venstre (umalet, ubelagt, kobber farve):

Another copper air nozzle with turning processing similar to the two products in the previous picture.
The difference is that this kind of gas nozzle has no external thread, it is embedded in the plastic part and fixed by insert. Similar to this kind of inserts generally have internal threads, this product has neither external threads nor internal threads because it is only used as an air nozzle. For eksempel, nozzles used in humidifiers
For plastic embedded copper parts with internal threads, please refer to: plastic embedded inlay nut parts

Turned parts of two types of red copper and oxygen-free copper TU.
In addition to the common C3604 or H50 62 series brass, our company also produces red copper turning parts, TU oxygen-free copper turning parts, beryllium copper turning parts and phosphor bronze turning parts.
In the picture on the left, this copper turning part with flower teeth is similar to a rivet nut, but it has no internal threads. The characteristics of red copper are softer, and the tool sticks during turning, and its processing speed is lower than that of brass. Imidlertid, because of its relatively soft hardness, it is very good for pressing flower teeth or rolling threads. Checking the enlarged image shows that the embossing is clear and neat.
The other is a copper threaded turning part with milled edges

Flower tooth red copper turning parts

A copper turning part with threads at both ends. The effect after nickel plating
One end is threaded M4 and the other end is threaded M8, and a side hole ∮4.0MM is drilled on the thread. It is produced with hexagonal bar H13 copper bar, total length is 38MM

Turned parts with ball heads are made by one-time turning with a forming knife. The outer circle does not need to be polished, but it is as smooth as a mirror. The size of the left picture is H6.35 (maximum outer circle) *7.9 (total længde) *M3 (internal thread and hole diameter)
