How does an electric motor work?

Electric motor plays an important role when it comes to running a machine. Obviously, you always want to choose the best out of the best motors to run your machine. The main motto behind choosing a motor is to give power to a machine. When you decide to operate a mechanical machine using a motor, you need to go with it. Do you want to choose an...

Uses of Gear and Rack

Gears and racks are used especially to convert rotating force into desired linear motion. Here, you need to remember that a gear rack can have straight teeth on its surface. It can be in the form of square or round. It operates with a small-sized cylindrical gear called pinion.  Now, you would like to know the uses of gear and rack....

How to Measure V-Belt Pulleys?

Are you planning to choose a v belt pulley? If yes, then you need to choose a right according to your requirements. However, it’s true that you would always like to choose the right product, but still you may not be able to end up with what you really need. The key reason behind this situation is that you can’t be able to measure a pulley. ...

What is Extrusion Process?

The process begins by heating the stock material. It is then loaded into the container in the press. A dummy block is placed behind it where the ram then presses on the material to push it out of the die. Afterwards the extrusion is stretched in order to straighten it. If better properties are required then it may be heat treated or cold worked....

What is Deep Drawing?

Deep drawing is a compression-tension metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a tangential...

How does Coding Works?

Coining is a form of precision stamping in which a workpiece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. A beneficial feature is that in some metals, the plastic flow reduces surface grains size, work hardening the surface, while the material deeper in the part retains its toughness and...

What is Fine blanking?

Fine blanking is a fully automated precision metalworking process. It is a form of precision metal stamping in which extremely tight tolerances can be held, and usually additional machining steps can be avoided post-production. Materials that can be fine blanked include carbon steels, alloy and stainless steels, as well as soft non ferrous alloys...

What is Piercing metalworking?

Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. The process and machinery are usually the same as that used in blanking, except that the piece being punched out is scrap in the piercing process.There are many specialized types of piercing: lancing, perforating, notching, nibbling, shaving,...

What is Metal Stamping?

Stamping is a metalworking process by which sheet metal strips are punched using a press tool which is loaded on a machine press or stamping press to form the sheet into a desired shape. This could be a single stage operation where every stroke of the press produce the desired form on the sheet metal part, or could occur through a series of...

Choice Of Lubricants for Worm Gear Reducers

Choice Of Lubricants The reducer should be filled with the appropriate oil to the center of the oil gauge before putting in operation. Excessive oil levels result in higher operating temperatures which is as undesirable as using too little oil. After approximately 24 hours of operation the reducer must be drained, flushed thoroughly with light...
