What is CNC Machining?

CNC machining, or Computer Numerical Control machining, is a super precise and automated way of making custom parts and components. Basically, it's like magic with machines! Instead of human hands, we let computer-controlled machines and tools do the work. They skillfully carve away material from a workpiece, making it into the exact shape and size you need. CNC machining is a go-to in all sorts of industries like aerospace, automotive, medical, and electronics. Why? Because it's like having a reliable robot craftsman – always accurate, does the job the same way every time, and gets things done super efficiently.

How Does CNC machining Work?

CNC machining services kick off by creating highly detailed manufacturing instructions using cutting-edge CAM (Computer-Aided Manufacturing) software. Starting with the customer's CAD model, our engineers input the design into the CAM software, crafting exact tool paths customized for the project's needs. Once these tool paths are set, the CAM software generates G-Code – a series of machine instructions that tell the CNC equipment how to carry out the manufacturing process. These instructions cover vital elements like speed, direction, dimensions, coordinates, and more.

» Read More

Once the G-Code is sent to the CNC machines, the manufacturing process springs to life. The CNC machine, equipped with multiple axes for movement, dances to the tune of its motors and servos, precisely guiding the cutting tools as per the programmed instructions. Sensors play a crucial role throughout this intricate process, ensuring accuracy and consistency in every dimension and detail. This careful approach to CNC machining makes it possible to produce intricate and accurate designs, proving its importance in various industries. Our CNC machining services are crafted to efficiently deliver top-notch components, highlighting the significant role of this technology in advancing manufacturing capabilities.

Metalworking CNC Milling Machine

CNC Machining Processes

CNC Milling

CNC milling is a technique in manufacturing where computer numerical control is employed to accurately eliminate material from a workpiece with rotating cutting tools. This milling machine has the ability to move in various directions, enabling the creation of a diverse range of shapes, slots, holes, and other details. It's a go-to method in industries like aerospace, automotive, and manufacturing for crafting intricate parts and components.

CNC Turning

CNC turning, often referred to as lathe machining, is a method where a workpiece spins on a spindle, and a cutting tool shapes it into cylindrical or conical forms. It's a handy technique for making things like shafts, pins, and cylindrical parts that need that rotational symmetry.

Different Types of CNC Machines

1. CNC Milling Machine

A CNC milling machine is your go-to for a variety of milling tasks, chipping away at a workpiece with rotating cutting tools. These machines boast the flexibility to move in different directions, giving you the freedom to craft intricate shapes and features effortlessly.


  • Precision machining of intricate parts.
  • Production of prototypes and molds.
  • Manufacturing components for aerospace, automotive, and medical industries.

2. CNC Lathe (Turning Center)

» Read More

CNC lathes, also known as turning centers, are used for machining cylindrical and conical shapes by rotating the workpiece while a cutting tool removes material. This exact process is ideal for creating shafts, pins, and other components with rotational symmetry.


  • Production of cylindrical components.
  • Turning and facing operations.
  • Mass production of parts with high precision.

3. CNC Router

CNC routers are specialised machines that cut, shape, and engrave materials like wood, plastic, and composites. They use a spindle and several cutting instruments to execute a variety of jobs precisely.


  • Woodworking and cabinetry.
  • Sign making and engraving.
  • Prototyping and modeling.

4. CNC Plasma Cutter

CNC plasma cutters cut through electrically conductive materials such as metal with a high-velocity stream of ionised gas. To achieve exact cuts, the equipment drives the plasma flame along a predetermined route.


  • Metal fabrication for construction and automotive industries.
  • Custom metal artwork.
  • Industrial manufacturing of metal components.

5. CNC EDM (Electrical Discharge Machining) Machine

CNC EDM machines use electrical discharges to remove material from a workpiece. This process is particularly effective for machining intricate shapes and hardened materials. Two common types are Wire EDM and Sinker EDM.


  • Tool and die manufacturing.
  • Production of complex, precision components.
  • Aerospace and medical device manufacturing.
