Double-headed mitre saws for aluminium profiles

Components are mitre-cut when they are to be joined at an angle to one another. For example, window profiles are generally mitre-cut at 45° to give a clean joint at the four corners. Thus, a mitre cut always refers to the sawing of a component at an angle. It is important for the elements to be joined to be as thick and wide as one another; otherwise, their cut surfaces will not form a clean joint.

Due to the particular properties of aluminium, there are certain requirements for the machine tools. Aluminium has low strength properties, which makes the material prone to external mechanical influences. The required stability is achieved by shaping the material, for example into profiles. As a soft metal, aluminium is noted for its low mass, which makes it easy to handle. These aspects are important in the construction of double-headed mitre saws that specialise in aluminium fabrication. The actual process of cutting through the material using the teeth on the saw blades must be perfectly balanced: fast fabrication, clean cut surfaces and low wear are important objectives to be achieved when developing the machines.

Computer numerical control (CNC) technology has been elevating machine tool technology to new heights in recent years. This technology allows a machine to be operated with relative ease. In principle, CNC machines allow fabricators to meet highly complex requirements.

This benefit can be applied to double-headed mitre saws by fitting them CNC technology. For example, the operator can send swivel and tilt angles to the integrated computer: a control panel is used to enter the necessary information directly into the machine.

You can also save data once it has been entered. If you need to repeat a certain order, you can retrieve the saved data. This saves time when preparing orders.
