Frequently asked questions

How much does CNC machining cost?

The cost of CNC machining depends on the complexity and size of the part and the type of material that is used. These variables will affect the type of machine that is required, the time it takes to produce the part, and the cost of the raw material. We use machine learning algorithms to calculate the exact cost of any machinable part directly from a CAD file.

What is metal machining?

Metal machining is a manufacturing process that involves cutting a piece of raw metal until a final desired shape or object remains. With CNC metal machining, unwanted geometry is cut from a raw block of metal, bit by bit with a computer numerically controlled (CNC) milling or turning cutting tool.

What plastic is best for machining?

ABS is a great general-purpose plastic for CNC machining as it has good machinability and dimensional stability. For applications that require low friction and high stiffness, POM is a viable option. Other plastics can be good choices for applications that have more particular requirements.
