Finixa SAM 50 Pneumatic Orbital Sander Ø150 mm: Precise Finish with 2.5 mm Stroke
The Finixa SAM 50 is a lightweight, ergonomic pneumatic orbital sander designed for clean finishing work, fine transitions, and controlled surface preparation. In this guide, you will find practical reference values, a clear workflow, and typical solutions for sanding pattern issues.
Product Overview: What is the SAM 50 suitable for?
The SAM 50 is designed for user comfort, controlled sanding, and efficient dust extraction. The 2.5 mm version is particularly suitable for finishing work with fine grits, while the 5.0 mm version is designed for coarser preparation work.
| Feature | SAM 50 / 2.5 mm Stroke | Practical Benefit |
|---|---|---|
| Sanding Pad | Ø150 mm, Velcro, 15 holes | Large contact area and good dust management |
| Recommended Range | Finish, approx. P400 to P3000 | Fine sanding pattern before painting, polishing, or rework |
| Speed Control | Stepless, 0–20,000 RPM | Adjustable to surface, grit, and desired removal control |
| Weight | 790 g incl. sanding pad | Comfortable for long finishing sessions |
Recommended Basic Settings
The following values are practical guidelines. Depending on the paint structure, sanding disc, extraction, compressed air system, and desired finish, they should be tested on the workpiece.
| Application | Grit | Pressure / Guidance | Note |
|---|---|---|---|
| Finish Sanding | P400–P800 | Light to medium, guide machine flat | For even transitions before further buildup |
| Fine Sanding / Rework | P1000–P3000 | Low pressure, controlled movement | Ideal for controlled finishing with 2.5 mm stroke |
| Test condition per TDS | P240 Aluminum Oxide | 30 ± 5 N, 90 psi | Test value, not automatically the maximum or ideal value for every application |
Professional Workflow in 6 Steps
- Check Surface: Clean surface, complete degreasing, and avoid dust.
- Choose Suitable Grit: Stay in the finishing range for the 2.5 mm version and do not start too coarse.
- Check Extraction: Align the hole pattern of the sanding disc cleanly with the 15-hole pad.
- Adjust Speed: Start with a moderate setting and only increase if the sanding pattern remains stable.
- Guide Machine Flat: Do not tilt, avoid point-loading, and move with even overlaps.
- Inspection: Clean the sanding pattern, check with light, and only then move to the next grit.
Troubleshooting: Typical Problems and Quick Actions
1. Swirl Marks or Uneven Sanding Pattern
- Reduce pressure and guide the machine flat.
- Check grit and do not make too large jumps between grit sizes.
- Change the sanding disc if it is clogged or damaged.
2. Sanding Disc Clogs Quickly
- Check extraction and hole pattern.
- Clean the surface thoroughly before sanding.
- Reduce speed and pressure if heat is generated.
3. Too Little Material Removal
- Check if the grit is suitable for the task.
- Check compressed air supply and speed.
- For coarse preparation, use the 5.0 mm version instead.
4. Fatigue During Long Work Sessions
- Set workpiece height ergonomically.
- Guide the machine loosely and do not press down continuously.
- Plan regular short breaks, especially for serial work.
Maintenance and Care
- Regularly check the sanding pad for damage, wear, and flat rotation.
- Keep the Velcro surface clean so sanding discs adhere securely.
- Ensure the compressed air supply is clean and correctly adjusted.
- Keep dust channels and extraction paths clear.
- Store the machine in a dry place and clean the exterior after intensive use.
FAQ for the Finixa SAM 50
Which grits are the 2.5 mm version intended for?
The 2.5 mm version is intended for finishing work in the range of P400 to P3000.
When does the 5.0 mm version make more sense?
The 5.0 mm version is more suitable for coarser preparation work where more material removal is required.
What role does the 150 mm sanding pad play?
It offers a large working surface and supports efficient dust extraction with its 15-hole system.
How loud is the SAM 50 according to the TDS?
The declared emission sound pressure level at the operator station is 79.0 dBA. The sound power level is specified as 90.0 dBA.
Are the test values automatically practical maximum values?
No. The TDS values are average or test values and should always be validated on the material for your own specific application.
