What Is the Thread Rolling Process?
How do you make screws, bolts and similar? Today, we talk about the thread rolling process. What is the thread rolling process? The thread rolling process allows the cold forming. The threats are formed on cylindrical sections and making them go through 2 molds that translate and rotate. How do you get the profile? During […]
Wire Cold-Processing Technologies
There are 3 types of cold-processing of wire. Here they are specifically treated. What are the technologies? METHOD OF DIRECT EXTRUSION (see figure 3.0 – 8) This method reduces the diameter where the percentage reduction shall be free or it is limited by the materialâs ability to enter into a smaller diameter mold. METHOD OF […]
Fasteners Production â Find Out The Plastic Deformation
Today we talk about the fastener production by plastic deformation. What are the processes of massive deformation? They are all those processes in which the preforms thereof undergoes plastic deformation under the action of forces that are enforced by different types of the mould and equipments. How these processes are classified? On first, they depending […]
The Thread Turning
The thread turning. Today, our post talk about thread turning. Specifically, about what is and how do it? What is the turning? Feed per revolution is the thread pitch. The tool bit is shaped with a profile that matches that of the thread. The tool advances by one step for each revolution of the work […]
Threading Process â Tip And Dies
Threading process Today we want to talk again about of the execution of threads. After males and tap wrenches, we want to talk about tap and dies. What do tip and dies do? Tip and dies enable a thread out of a cylindrical bar with diameter that corresponding to the thread nominal diameter that we want […]
Threading Process â Tap and Tap Wrenches
Today we want to talk about the threading process, and in particular about taps and tap wrenches. What are taps and tap wrenches? Tap (male) consist of a cylindrical body with straight or helical grooves that separate the combs groove rope. Tap wrenches are tools for tapping manual. They have two arms that allow the […]
Fasteners â What Is the Production by Shaving Removal?
Shaving Removal. There are two several realizations of threads removal. External and internal threads. Letâs find out.. Different methods The thread execution process by shaving removal consists of different methods. Let us see them together: Internal and external threads INTERNAL THREADS The process of tapping is when the internal threads are obtained by a special […]
Retaining Rings â Why Use Stainless Steel AISI 420 or AISI 403 (2XCr13)?
Today, we will show you why use stainless steel AISI 420 or 403 for retaining rings. A little more information These type of steels belong to the family of martensitic stainless steels. They are ferromagnetic, hardenable and they have a sufficient corrosion resistance in moderately corrosive environments. In fact, they have low and medium carbon […]
Production of Fasteners â What Are the Technological Processes?
Fasteners can be produced through three basic technological procedures. Why donât we find out them together? Which are the processes? As stated above, there are three different technological processes for the production of fasteners: Letâs see them in particular! Shaving removal This type of process start with bars. These are then processed on automatic lathes, […]
DIN 3506-3: Hardness Class. It Doesnât Add Up!
Today we would like to bring to your attention a controversial topic. We are talking about stainless steel hexagon socket set screws. The preconditions We acting on the assumption that hexagon socket set screws donât have head, quality tests doesnât provide the resistance measuring. They are distinguished in the following hardness classes: Please find below […]
