Comprehensive study material for ITI technical trades, including Fitter Electrician and others. Covers NIMI pattern theory, workshop practicals, safety standards, and industrial manufacturing processes.
A metal is a solid material, which means typically hard, non-transparent, and has good electrical and thermal conductivity. Metals are generally malleable because they can be hammered permanently out of shape without breaking or cracking. These are fusible, i.e., able to be fused or melted, and ductile, i.e., able to be drawn out into thin … Read more
Life, as we know it, is a symphony of interconnected parts. From the intricate gears within a watch to the massive components of a power plant, every machine, no matter how grand or modest, is an assembly of meticulously crafted pieces working in harmony. I remember vividly, back in my early days of tinkering with … Read more
Grinding machines are a vital part of machining processes in various manufacturing Industries, including automotive, aerospace, and electronics. A workshop that deals with these industries must incorporate grinding machines in their manufacturing process. Grinding machines are used to shape: and finish metal and other materials to exact specifications. Key Takeaways: Grinding machines are essential for … Read more
Introdution The hole drilled by the drilling operation is rough on the inside and not as accurate as required. Also, for the perfect fitting, accuracy, and finishing of the hole is most important. Therefore, a process is required that provides a fine finishing surface to the hole and ensures the hole is more accurate. That … Read more

Introduction Welding is the art of joining materials. It is a fabrication or sculptural process that joins the materials, usually metals or thermoplastics, by causing coalescence. Normally, in welding operations, the joining of metal pieces is done by raising their temperature to the fusion point so that they form a pool of molten metal that … Read more
Soldering and brazing are the processes of joining similar or dissimilar metals. There are three processes of joining the metals i.e., soldering, brazing, and welding. The major difference between them is that a huge amount of heat is required in the case of welding, a low amount of heat is needed in the case of … Read more
It is the simplest and most accurate machine, which is used in production shops. The workpiece is held stationary i.e., clamped in position and the drill rotates to make a hole. It is designed specifically to operate drilling and similar operations. Drilling machines are classified based on their constructional features and the types of work … Read more
Drilling is an operation through which holes are produced in a metallic or non-metallic material through a revolving tool called a drill. The whole process is carried out on a specific machine known as a drilling machine. The machine provides rotatory motion to the drill and is directed toward the workpiece where the hole is … Read more
