Individual Load System Automatic Polishing Machine Rana-3
back to the list
The Rana-3 is designed with an individual load method, and 1 to 6 samples can be set freely.
Since the holder rotation speed can be changed, the holder and the disc can be polished at the same rotation speed, and the polished surface does not tilt or become pencil-shaped.
he holder and the disc can rotate forward and backward.

Polish without losing parallelism!
With the recommended polishing method, the holder and disc should rotate at the same speed and in the same direction in order to perform grinding with no loss po parallelism in the workpieces.
Rana-3 allow the rotation speed of the holder to be changed, which makes it possible to grind workpieces in the same direction and at the same rotation speed with no loss of parallelism.
In addition, the disc and holder rotation can be reversed, allowing for easy hand polishing even for left-handed users.
- Grinding: SiC paper or polishing pad
- Disc rotation speed: 200rpm/Holder: 200rpm
- Fine polishing: DIA ＋polishing cloth
- Disc rotation speed: 65 to 150rpm/ Holder: 65 to 150rpm
-
Automatically increase/reduce pressure for the set number of seconds
Both Rana-3 and 30 machines can automatically increase or reduce the pressure applied to a specimen.
This function can be configured to increase pressure gradually for the set number of seconds from start.
The settings can also be configured to increase or decrease pressure gradually at the set number of seconds. -
Change polishing conditions(pressure, rotation speed) in two steps!
Two different movements can be programmed to a single polishing process to enable variations.
for example. With fragile material and material with sharp edges, operation can start at low pressure and low speed, gradually increasing to a higher pressure and higher speed. -
Memory for up to 16polishing conditions!
Up to 16 polishing conditions can be programmed.
When preparing more than one specimen, polishing conditions can be set for each specimen, allowing fore efficient operation.
