Basics

This article is all about the tools that welders want to have in their shop. They make welding easier, and in many cases, they make the welding process — from start to cleanup — more enjoyable. If you’re new to welding and you have a birthday coming up, you’re going to want to start dropping hints about…

As the name implies in Laser beam Machining the source of energy is the LASER (Light Amplification by Simulated Emission of Radiation) . The laser beam focuses optical energy on the surface of the workpiece. A laser beam can be so powerful when used with lens system that it can melt and vaporize diamond as the energy density can…

The source of energy in electron beam machining is high velocity electrons, which strikes the surface of the workpiece and generate heat. Electrons escapes from the hot surface and a voltage of 50 to 200 kV helps to accelerate them. These high energy electrons possess high energy density generally in the order of 10ˆ4 kW/mm² . Thin and high…

Raw materials of irregular size and shape has very little value. So to impart some function ability in the raw material we have to add some values to it. By production or manufacturing process an irregular shaped work piece is converted into a high utility product. This finished product has desired size, shape and meets our requirement. In…

Types of Reaming tools / Reams Reams are needed to ensure exact size of the hole . It also provides great surface finish. A small amount of material is remove from the drilled hole. Reamer can be hand operated or machine operated. But they should be operated at slow speed.  Names of the different types of reams are as follows –…

In lathe machine the work part is rotates and the tool remains stationary . Lathe machine operations involve the turning , drilling, facing, boring threading and many more. Various tools and different orientation of the tool is used to get the desired shape.  All these methods are mainly basic turning operations. Lets discuss these methods….

In lathe machine a rotating workpiece is held between the rigid supports while a stationery tool is used to cut the workpiece to give the desired shape. It is very important machine for metal cutting. Different parts of lathe machine are needed to be known to conduct the machining work perfectly. So lets discuss in…

Coolant The role of coolant in CNC milling machine is vital. It improves tool life and ensures smooth machining of the work. The different coolant used in CNC milling includes Mist Coolant, Flood Coolant, Cool Air Gun or Air Blast coolant and Dust Collector. Actually, the dust collector is not a coolant but it creates…

Complete CNC Milling Machine Parts Frame Frame lies above the ground or foundation of CNC milling machine. It works as a support and also damper for the machine vibration. The material of the frame may be Cast Iron or granite filled welded structure. Barely steel is not used generally as a milling machine frame because…

It is observed that a higher temperature object which is in contact with a lower temperature object will transfer heat to the lower temperature object. The objects will approach the same temperature, and in the absence of loss to other objects, they will then maintain a constant temperature. They are then said to be in thermal equilibrium. Thermal equilibrium…
