We at MDA know the importance of machining parts and components. We believe that every client has different needs and to fulfil them, we use intricate CNC machining parts that are ideal for the project.

In this guide, we are going to cover machining parts, types of machining parts, advantages, applications, and more.

What are CNC Machining Parts?

CNC machining parts can be made from various materials, including metals, plastics, and composites. The design specifications for these parts are programmed into the CNC machine, which then follows these instructions to cut, shape, and form the raw material into the desired final product. CNC machining is widely used in industries such as aerospace, automotive, medical, and electronics due to its ability to produce parts with tight tolerances and high accuracy.

Examples of CNC machining parts include:

  • Precision Components
  • Prototypes
  • Tooling and Dies
  • Custom Parts


Why use CNC Machining Parts?

There are plenty of reasons why industries, product designers and other professionals might use machining parts, as they offer plenty of flexibility. In short, machining parts have excellent strength and they can be made into a wide range of shapes.

Industries also use machining parts because machining is a tried-and-tested manufacturing technique that has been the industry standard for decades. Machining parts are therefore likely to meet industry-specific standards and certifications. Let’s first, check out the machining techniques and processes.

What are Machining Techniques and Processes?

Machining encompasses a variety of techniques and processes used to shape raw materials into finished parts and components. Here are some key machining techniques and processes:

#1. Turning

In turning, a workpiece rotates while a cutting tool removes material to create cylindrical shapes. This process is commonly used for producing shafts, rods, and other cylindrical components.

Applications: Turning is widely employed in the production of parts like bolts, screws, and bushings.

#2. Milling

Milling involves the use of rotary cutters to remove material from a workpiece, creating complex shapes, slots, and holes. It can be performed in various directions, including vertical, horizontal, and multi-axis milling.

Applications: Milling is versatile and is used to manufacture components such as gears, brackets, and engine components.

#3. Drilling

Drilling is a machining process that creates holes in a workpiece using a rotating drill bit. The drill bit is pressed against the workpiece to remove material.

Applications: Drilling is a fundamental process for creating holes in components like engine blocks, panels, and structural elements.

#4. Grinding

Grinding uses abrasive particles to remove material from a workpiece, achieving tight tolerances and smooth finishes. It is employed for precision machining where high surface quality is critical.

Applications: Grinding is commonly used for finishing operations on components such as bearings, molds, and cutting tools.

#5. CNC Machining

CNC (Computer Numerical Control) machining involves the use of computer programs to control machine tools. It includes processes like milling, turning, and drilling, and allows for precise and automated production.

Applications: CNC machining is utilized in a wide range of industries for producing complex and high-precision components.

#6. Laser Cutting

Laser cutting uses a focused laser beam to cut through materials. It is a non-contact process that produces clean and precise cuts.

Applications: Laser cutting is widely used for creating intricate patterns and shapes in materials like sheet metal, acrylic, and wood.

#7. Electrical Discharge Machining (EDM)

EDM uses electrical discharges to remove material from a workpiece. It is suitable for machining conductive materials and can create intricate shapes with high precision.

Applications: EDM is often used for producing molds, dies, and components with complex geometries.
