Process and Process Details

The process involves 2-axis diamond turning (X, Z) with tool radius measuring 0.5mm, spindle speed of 2,000 rpm, and feed rate of 5mm/minute. The depth of cut is fixed as 2µm and the coolant used is odorless mineral spirits.

Part Details

The measurements of the parts are as follows:

  • Material: aluminum
  • Spherical radius: 2.5mm
  • Outer diameter: 8mm
  • Maximum slope: 52 degrees

Measurement Methods

The finish method requires the use of Taylor Hobson CCI instrument. The sample area measures 150µm x 150µm. The form method requires the use of the form Talysurf instrument.

Results

The Nanoform® X is capable of achieving surface finish and form accuracy results. The surface finish result procured was 1.43nm Sa, and the form precision measured 0.058µm PV and 0.013µm RMS.
