Machining Processes:

There are many different types of machining processes, each of which has its own advantages and disadvantages. Some of the most common include:

Conventional Machining Process

Any manufacturing process in which the material removal from the work piece by direct contact of cutting tools on the work-piece to get the desired shape.


In this machining process, a drill bit is fed into the workpiece, to create a hole in the workpiece. The material is removed from the workpiece as the drill bit is rotated into it. Drilling is typically used to create holes of various diameters and depths.


In Boring process, the tool is used to enlarge the size of the previously drilled hole in the work piece. Boring can be done to produce a smooth finish on the inside of the hole or to enlarge the hole to a specific size. The boring process can be performed on a variety of materials, including wood, metal, and plastic.


Milling operations involve the use of rotating cutting tools to remove material from the surface of a work piece. It can be used to create flat, curved, or irregular surfaces, contoured surfaces, and complex shapes. The milling process can also be used to create threads, grooves, and other types of features on a work piece.


Turning is a machining process in which the work piece is rotated against a cutting tool. The cutting tool is fed into the work piece, and material is removed from the work piece as it is rotated. It is typically used to create cylindrical shapes of any size.


Broaching is a machining process that uses a toothed tool, called a broach, to remove material from a work piece. It is performed by pushing or spinning the broach through the work piece. It is commonly used to create keyways, slots, and other internal shapes. Broaching can also be used to create external shapes, such as splines and serrations.

Gear forming

In gear forming, the teeth of a gear are being cut while it is meshed with another gear. The gear being cut, is called the blank, which is usually softer than the cutter gear. For spur gears, the blank is usually rotated in a lathe. It is usually manufactured from hardened steel.


Grinding is a machining process in which the work piece is moved against a rotating abrasive wheel. The abrasive wheel removes material from the work piece as it is moved. It can be used to create a smooth finish on the surface of the work piece.


This process is to create shorter length of extruded bars or similar structures and shapes, by using the Cut-off machines (or) simply called as Saw machines. Its speed depends on the type of material, for example softer materials like Aluminium alloys require high cutting Speed whereas, some high temperature alloys can be cut off on low cutting speed

Gear Generation

The gear generation process is used to cut the teeth of a gear. The cutter gear has the same tooth form as the gear being cut, but is usually made of hardened steel. The gear blank is rotated and the cutter gear is fed into the blank. The cutter gear cuts the teeth of the gear blank.


In terms of materials, machining is typically used for metals and plastics, as well as a wide range of other materials with sufficient hardness for the operation of the machine tools. There are a wide variety of materials used in the machining process. Each material offers unique benefits and should be carefully chosen to ensure the best results for a particular manufacturing project.

Steel is the most popular machining material due to its strength and versatility, while aluminum, copper and plastic are also widely used. With the right material and careful selection, machining can be an efficient and cost-effective means of producing a finished product.

Common metals used in machining include steel, aluminum, brass and bronze.


Plastics are another common machining material, due to their low cost and ease of machining. However, plastics are not as strong as metals and can be damaged easily.


Ceramics are harder than metals and can be used for cutting tools and wear-resistant parts. However, they are brittle and can break easily.


Composites are materials made from two or more different materials. They can be strong and lightweight, making them ideal for many applications.

But also, the choice of material is dictated by the properties required for the finished part, such as strength, hardness, wear resistance, corrosion resistance or conductivity. Zastata is a professional and experienced machining option, uses a strictly controlled environment to offer high performance and high-quality products. We have a wide range of premium machining materials and equipment’s to help you achieve the capability of your desired component requires.
