Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which dif

Today we will discuss about difference between NC and CNC machine. NC stands for numerical control whereas CNC stands for computer numerical control. Both of these are automatic machines which are used for machining any metal with accurate dimensions. These both machines work on feeding mechanism i

Today we will learn about what is forging and types of forging. Further we will discuss about operation, application, advantages and disadvantages of this process. Forging is a metal forming process in which the metal is heated and a force is applied in such a way that a required shape can be obtai

Today we will learn about forging defects types, causes and its remedies.Defects are common in every manufacturing process like casting includes casting defects, welding includes welding defects, same as forging consist some defects which are due to both process and human limitations. Forging gives

Today we will learn about extrusion process working, types, application, advantages and disadvantages. Extrusion is a metal forming process in which metal or work piece is forced to flow through a die to reduce its cross section or convert it into desire shape. This process is extensively used in p

Today we will learn about rolling process types, working, terminology and application with its diagram. Rolling is a major manufacturing process of sheets and other cross sections of large length like I beam, railroads etc. It is one of a  metal forming process in which the metal work piece is comp

Rolling process is most common industrial process used for making large length cross section like sheets and plates of steel and aluminum for structure and other works. Rolling mills are used to perform rolling process. These machines are available in different shapes and size according to requirem

Today we will learn about drawing process Working and its types like wire drawing, rod drawing and tube drawing. Drawing is a metal forming process used to reduce cross section and increase length of work piece. This process associated with tensile force which distinguishes it from other metal form

Today we will learn about swaging process. Swaging is a metal forming process of reducing diameter of a rod or tube by forcing it into a die with the help of reciprocating blow. This will plastically deform the metal and force it to flow into die and acquire die cavity shape. The fundamental conce

When we talk about manufacturing process, we can’t end our discussion without describing Sheet metal processes. The word “Sheet Metal” is used for metal sheets of varying thickness. In our daily routine we often encountered with sheet metal products. When you see a car the first thing you like its

Sheet metal processes are versatile processes used in metal forming industries. Due to its various advantages, sheet metals are widely used in manufacturing industries. All cars bodies, metal doors, fan blades, metal desks etc. are sheet metal products. There are various processes to transform shee

Today we will learn about deep drawing process. Deep drawing is a sheet metal forming process. Metal sheets are largely used in manufacturing industries due to its easy operation, light weight and ability to be converted into various shapes. Sheet metal also provides good strength. There are variou

Today we will learn about electron beam welding, principle, working, equipment’s, application, advantages and disadvantages with its diagram. Electron beam welding is a liquid state welding process. Liquid state welding are those welding processes in which, the metal to metal joint form in liquid o

Today we will learn about resistance welding principle, types, application, advantages and disadvantages. Resistance welding is a liquid state welding process in which the metal to metal joint created in liquid or molten state. It is a thermo-electric process in which heat is generated at the inter

Today we will learn about gas welding principle, working, equipment’s, types, application, advantages and disadvantages. Gas welding is a type of liquid state welding process in which fuel gases burns to generate heat. This heat is further used to melt interface surfaces of welding plates which are

Today we will learn about types of welding flames used in gas welding. In my last post, we have discussed about gas welding. In this welding process gases fuels are burn and produce high temperature flames which further used to create weld joint. The flame plays lead role to create weld joint and

Today we will learn about what is casting its working process, advantages, disadvantages and main casting terminology. Casting is defined as a manufacturing process in which molten metal pure into a mold or a cavity of desire shape and allow to solidify which form a predefine shape. This process is

Today we will learn about types of pattern used in casting. Pattern is replica or model of object which to be created. It is used to make hollow cavity in sand mold in which molten metal is poured and allow solidifying to create object. The size and shape of cast object is highly depends of shape a

Today we will learn about different types of allowance used in pattern making. The pattern is replica of casting but it has slightly large dimension.  This change in dimensions in pattern and casting are due to various allowance used in casting. When the cast solidify, it shrink at some extent due

Today we will learn about centrifugal casting its working principle, types, application, advantages and disadvantages. Centrifugal casting is one of the most important type of casting process in which mould is rotated rapidly about its central axis during casting is solidified or metal is poured.
