6061 Quick Turn Machining

3 Day Turn On Low Volume Parts

We stock Aluminum 6061 in order to deliver parts in three days. Add a day for plating.

We generally work with 3D models: Native Solidworks, Step, or Parasolid. We get the demensions from the model in the CAM and machine to ISO 2768 Linear Standards. There are some things we cannot always determine so please specify the following:

  • Material The material does not come through with a step or parasolid file. It is best to include it on drawings.
  • Finish The finish as well does not come through in step or parasolid files. It is best to include it on drawings.
  • Tapped Holes Including these on the drawing avoids guess work.
  • Any Tolerances greater than +/-0.127mm[.005"] We machine to ISO 2768 Linear Standards which are a bit tighter. Industry standard has been +/-0.127mm[.005"] so it is good to call out any tolerances greater than this. These include: Dowel Pins, Bearings/Bores, Keyed Pockets.
  • P/N and Revision These are optional. If you want clear communication include these.

A general purpose readily available age hardening aluminum alloy. The base material is a good conductor of heat and electricity. Surfaces exposed to atmosphere will quickly form a hard aluminum oxide layer. This outer aluminum oxide layer will naturally protect the base aluminum from further exposure. The aluminum oxide layer is a good conductor of heat, but not a good conductor of electricity. Aluminum 6061 can be post processed and plated to achieve better corrosive, electrical, and cosmetic properties.
