About CNC Turning

When engineers want to know if a specific part of a design is going to work, they look to CNC Turning. The finished article is used to create pieces of machinery that are often highly-complex. A typical car has around 10,000 parts alone.

A trained operator will be familiar with many types of materials, ensuring the dimensions of the finished piece exactly match the design specifications

The Challenge

Competitors are required to:

• Prepare part programs for components to be machined on the CNC lathe through the machine control unit and/or Computer Aided Machining software (CAM)
• Set up and operate CNC lathe to produce precision components to dimensional accuracy of 0.01mm and obtain surface roughness of up to 0.8 micron

CNC turning and milling – what’s the difference?

the answer, others may find this a useful insight into what goes on behind the scenes in the world of metal fabrication!

CNC machining

• With CNC turning a metal bar is fed into the lathe and rotates at speed while a single-point cutting tool removes portions of the metal to create the desired shape.
• With milling the metal usually remains still while multi-point cutting tools rotate around it.

Turning

Items processed by a lathe will be cylindrical and must be on-centre. Turned parts can range from simple rings to complex curved components. CNC turning is the most efficient way to mass-produce these kinds of parts.

Various cutting tools can be installed within the lathe tooling head (pictured below) to perform different cutting operations sequentially, to produce parts in a one-pass process. Straight cuts, tapers and contours can all be created by varying the angle and depth of the cut.

awing carefully, don’t accept the order if we can’t meet the print requirement, we don’t ship out the parts if the parts failed to meet the customer’s requirements.

FAQ

When do not make parts by 3D printing?

• Mass production. When you have hundreds or thousands parts to make, the parts can be made by CNC machining, die casting, sand casting, forging, or powder metallurgy, the unit price could be much lower.
• Smooth finish. The CNC turning can get at least Ra0.8 μm roughness, CNC milling can get at least Ra0.8 μm roughness. Currently the 3D printing parts can’t have as fine surface as CNC machining.
• Special material. For CNC machining, you can have different grade material from different material supplier, for example you can select AISI 316L stainless steel for CNC machining, but for 3D printing, you can only have “stainless steel” for option, the material property will have slightly difference.
• Heat treatment. So far the 3D printing metal parts have brittle surface, the machined parts can do heat treatment, so the machined parts could have better mechanical property.
• Tight tolerance. CNC machining can meet very tight tolerance(as tight as μm grade), 3D printing can’t as precise as CNC machining.
