Here at TNN Engineering the majority of machine tools are CNC machines. We have CNC turning, milling and multi-tasking machines suitable for both rapid prototyping and production quantities. Computer controlled machines produce superior components with improved quality, accuracy, consistency and reduced machining times.

Precision CNC Turning

CNC Lathes
Whether you want one pin or a hundred shafts, we have the expertise and capacity to deliver your turned components.

TNN has numerous CNC Lathes including conventional 2 axis machines & multi-tasking machines capable of up to 5 axis cnc machining. These multi-tasking machines can complete complex components requiring milling, drilling and turning in one single operation. We can create components up to 770mm diameter and 1500mm long. We also have a fully automatic bar-feeder capable of feeding 65mm bar stock.

“Our CNC Lathes produce components that have superior accuracy and consistency. These computer controlled Lathes have a resolution of 1 micron (0.001 mm) and use high precision backlash free ball screws to control tool movement. Faster spindle speeds and tool movement means bright and shiny surface finishes and reduced cycle times.”

What is Turning?
Turning is the process used to create cylindrical features and parts.  Turned components are produced on a Lathe where the work piece is rotated and a cutting tool is used to remove material.

Typical components that can be made are

  • Shafts
  • Bolts and Nuts
  • Flanges
  • Pins
  • Rollers
  • Pulleys
  • Sheaves
  • Shaft covers
  • Bearing caps

The types of features than can be machined on Lathes include

  • Internal and external threads
  • Spigots and recess for bearings and seals
  • O-ring grooves
  • Tapers
  • Sheave and pulley grooves
  • Chamfers and contours such as curves and radii

Our CNC lathes also have milling and drilling capability which reduces setups and increases accuracy.  Features that can be created on our multi-tasking lathes include:

  • Holes
  • Tapped holes
  • Counter bores and chamfers
  • Keyways
  • Profiles such as flats, triangles and hexagons
  • Oil grooves
