CNC Machining

CNC (Computer Numerical Control) machining uses computerised controls and machine tools to remove material from a workpiece to produce a custom-designed part or product.

CNC machin­ing is wide­ly used in var­i­ous indus­tries for its ver­sa­til­i­ty, pre­ci­sion, and efficiency. 

CNC machin­ing is a cru­cial tech­nol­o­gy in mod­ern man­u­fac­tur­ing, pro­vid­ing a flex­i­ble and pre­cise solu­tion for pro­duc­ing a wide range of com­po­nents across dif­fer­ent indus­tries, includ­ing aero­space, auto­mo­tive, elec­tron­ics, and med­ical devices.

Key Features

Computer Numerical Control (CNC):

CNC machining relies on computerised systems to control the movement and operation of machine tools.

CNC machines follow instructions from a pre-programmed computer-aided design (CAD) or computer-aided manufacturing (CAM) file, allowing for highly accurate and repeatable processes.

Types of CNC Machines:

  • Milling Machines: Used for cutting and shaping materials using rotating cutting tools.
  • Turning Machines (Lathes): Rotate the workpiece while cutting tools are applied to create cylindrical parts.
  • Drilling Machines: Used for creating holes in a workpiece.
  • Electrical Discharge Machining (EDM): Uses electrical discharges for precision cutting.
  • Water jet and Laser Cutting Machines: Utilise high-pressure water or lasers to cut through materials.

CNC Processes:

Our CNC machining processes include Milling, Tapping, Reaming and Jig boring.

Materials Used:

CNC machining can work with various materials, including metals (aluminium, steel, titanium), plastics, composites, etc.

The choice of material depends on the specific requirements of the end product.

Precision and Accuracy:

CNC machining offers high precision and accuracy, with the ability to produce complex geometries and tight tolerances.

The repeatability of CNC machines ensures consistent quality in mass production.

Programming:

CNC machines are programmed from 3d cad files / DXF / Step formats.

Automation and Efficiency:

CNC machining is highly automated, reducing the need for manual intervention.

Automation improves efficiency, reduces labour costs, and allows for continuous production.

Prototyping and Production:

CNC machining is used for prototyping and large-scale production, making it a versatile manufacturing method.

It is suitable for producing one-off prototypes as well as high volumes of identical parts.

Tool Changes:

CNC machines can be equipped with tool changers that automatically switch between different cutting tools during machining.

This feature allows for the production of complex parts with multiple machining operations.

Quality Control:

CNC machining often includes built-in quality control processes, such as measuring tools and probes, to ensure the accuracy of the machined parts.

Post-Processing:

Depending on the requirements, CNC-machined parts may undergo post-processing steps such as surface finishing, heat treatment, or assembly.
