CNC machining delivers high speed, high precision, and robust manufacturing solutions. You take a block or billet of material and cut away at it with a series of tools and drill bits, removing material to make CNC machined parts. At HLH, over 70 high precision CNC mills, lathes, sink and wire EDMs, and surface grinding machines help us deliver custom parts for many industries.
| Metal (standard) | Plastics (standard) | |
|---|---|---|
| Linear Dimension | ISO 2768-1 Fine | ISO 2768-1 Medium |
| Hole Diameters (Not Reamed) | SO 2768-1 Fine | ISO 2768-1 Medium |
| Shaft Diameters | ISO 2768-1 Fine | ISO 2768-1 Medium |
| Applicable Materials | Color | Description | |
|---|---|---|---|
| Anodizing | Aluminium, Titanium, Stainless Steel | Clear, black, grey, red, blue, gold | Anodising is used to increase surface hardness, wear resistance and durability of metals such as Aluminium and Titanium. |
| Painting | All metals and plastics | Black, RAL/Pantone colors | Painting is a well-known way to add colour. Overall, it is a great choice to improve the aesthetics of cnc machined parts. |
| Black Oxide | Steel, Stainless Steel, Copper | Black | Black oxide is a coating used to improve corrosion resistance and minimize light reflection. |
CNC or computer numerical control machining is a subtractive manufacturing method that leverage a combination of computerized controls and machine tools to rapidly remove layers from a solid block of material. The process produces custom high precision metal and plastic parts.
CNC vs 3D Printing
Compared with parts manufacturing through additive methods, CNC machined parts are functionally stronger and typically have superior production quality and finish. Thus, CNC machining is typically used in the mid to late stages of product development when parts are ready to be tested for functional accuracy.
Custom CNC Machining is Used For
High precision parts and rapid prototyping metal parts, performance plastics, and rapid low-mid volume production runs. When it comes to CNC machining, our approach is: provide highly flexible rapid low volume manufacturing solutions that deliver superior parts, fast.
Advantages of CNC Machining
CNC machining is subtractive machining manufacturing process in which pre-programmed software and code dictates the movements of factory tools and machinery.
Industries that use CNC machining include the aerospace, automotive, robotics, medical and electronics industries.
The standard machining tolerance is ± 0.005″ or 0.13mm. Tolerances are the allowable range for a dimension.
Generally, we would recommend CNC machining parts over 3D printing, as CNC machined parts are functionally stronger than those 3D printed and typically have superior production quality. This is why CNC machining is typically used in the mid to late stages of development, when parts are ready to be tested for functional accuracy.
