Figure 1. Nanoform X
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.
