Considerations like the intended use, necessary mechanical qualities, and simplicity of machining should be made while choosing the best aluminium for machining. It’s also essential to optimize machining parameters to achieve the desired results with each specific alloy cnc.

Combining CNC Machining with Other Processes

CNC machining is a versatile manufacturing process, and its synergy with other complementary processes can unlock new possibilities in terms of complexity, precision, and material variety. In this exploration, we will delve into how combining CNC machining with other processes enhances manufacturing capabilities across various industries.

CNC Machining + Laser Cutting

CNC Machining + Laser Cutting

Combining CNC machining and metal cutting laser cnc creates a powerful synergy in manufacturing. A metal cutting cnc laser provides precision and versatility in material processing, producing intricate patterns and fine details.

Integrating cnc metal laser cutting machine complements this by offering accuracy in complex features and surface finishes. The union of these technologies enhances design freedom, reduces material waste through optimized nesting, and enables the efficient production of components across various industries.

Metal cnc laser cutting machines result in a streamlined manufacturing process that achieves both intricate detailing and precision, making it a preferred choice for applications ranging from automotive components to electronics and consumer goods.

CNC Machining + Aluminum Extrusion

CNC Machining + Aluminum Extrusion

The method of cnc aluminium extrusion involves pushing molten material through a die’s opening to create an extended component with a continuous profile. Although cnc aluminum extrusion is a useful process for creating functional parts with high-quality surface finishes and intricate cross-sections, its use is restricted since the cross-sections must be uniform throughout the item.


Unless, of course, extrusion results in modifications to the component. The pieces produced by extrusion of aluminum can be post-machined, or cut in different ways, using a CNC milling aluminum machining center, because extrusion often involves malleable, ductile, and machinable grades of aluminum, such as 6061 and 6063. Creating strong products with intricate cross-sections and asymmetrical geometries is a terrific idea when combining extrusion and CNC machining.
