CNC Milling

CNC Milling uses rotary tools to cut and carve the desired workpiece from a block of material.

It utilises multiple axes to work on the component from multiple angles and deliver a high degree of precision. 

I&G Engineering use the latest 5-axis machining technology to manufacture complex parts on faster timescales than is possible with 3 axis milling.

CNC Turning uses a lathe or turning centre to spin a component around a central point, using a cutting tool to create the desired shape.

It is commonly used to create cylindrical parts. 

Our factory uses a wide range of Haas turning centres to produce high precision turned parts on a rapid scale.
