# WS 457 Pneumatic Belt Sander \u2013 For Precision Body Finishing<\/p>\n
The Wielander + Schill WS 457 pneumatic belt sander is a high-quality, high-performance tool specifically designed for the final machining of body surfaces and for performing precision work in narrow areas. This robust yet lightweight tool is the ideal choice for the quick and efficient removal and separation of weld points, weld seams (MIG-MAG, laser welding), and other materials.<\/p>\n
The main strength of the device lies in its extremely fine adjustability, which allows the user to continuously adjust the sanding speed by raising or lowering the arm to suit the specific task and material.<\/p>\n
## Main Application Areas<\/p>\n
The WS 457 belt sander delivers outstanding performance in the following areas:<\/p>\n
* **Weld Spot Removal:** Particularly effective for the safe and precise removal of weld spots on high-strength steels (e.g., Usibor, BTR-BOR).
\n* **Weld Seam Machining:** Excellent for finishing and leveling MIG-MAG weld seams as well as laser weld seams.
\n* **Accessing Tight Spaces:** Thanks to its compact design, it is ideal for sanding inaccessible, narrow body elements and hard-to-reach corners.<\/p>\n
**Important Note:** For the removal of weld spots, seams, and laser weld seams, the use of premium quality grinding belts with grit sizes K36, K60, and K80 is exclusively recommended for maximum efficiency and tool protection.<\/p>\n
## Technical Data and Properties<\/p>\n
The WS 457 pneumatic belt sander ensures reliable operation and a long service life thanks to its detailed technical parameters.<\/p>\n

### Infinitely Variable Speed Control<\/p>\n
One of the most important ergonomic and functional features of the belt sander is the **infinitely variable speed control**. By slightly moving the lever (raising\/lowering), the user can ideally adjust the speed to the grinding task (e.g., fine polishing or coarse material removal). This function increases workpiece quality and reduces the risk of overheating.<\/p>\n
### Robust and Ergonomic Design<\/p>\n
The tool is constructed from a combination of metal and plastic elements, which guarantees high durability even in workshop environments. Weighing only 0.85 kg, it is extremely light, enabling long, fatigue-free work, especially in hard-to-reach areas.<\/p>\n
## Pneumatic System Requirements and Maintenance<\/p>\n
Proper pneumatic supply and maintenance are essential to ensure the optimal lifespan and performance of the tool.<\/p>\n
### Recommended Accessories for Long Lifespan<\/p>\n
For the proper protection of the pneumatic system, Wielander + Schill recommends the following accessories:<\/p>\n
1. **Pressure Reducing Valve (7 bar, Part No.: 194000):** Overly high operating pressure significantly shortens the lifespan of pneumatic tools. This valve prevents damage and is recommended for all body repair tools.
\n2. **S\u0171r\u00edtett Leveg\u0151s Mini Ken\u0151olajoz\u00f3 (1\/4″, Cikksz\u00e1m: 637103):** Cs\u00f6kkenti a kop\u00e1st \u00e9s jav\u00edtja a szersz\u00e1mok m\u0171k\u00f6d\u00e9s\u00e9t.

\n3. **Pneumatic Special Oil (1000 ml, Part No.: 698001):** This high-performance oil is specifically designed for air lubrication systems and maintenance units, complying with viscosity class VG 32 according to ISO 3448 (32 mm\u00b2\/s at 40 \u00b0C). It offers excellent aging resistance, corrosion and wear protection, and outstanding demulsifying properties.<\/p>\n
Ensuring proper maintenance and air quality according to standards (ISO 8573-1) is crucial for the reliable operation of the tool.<\/p>\n
### Connection Accessories<\/p>\n
For quick and safe connection, the following elements can be used (not included in the package):<\/p>\n
* **Quick connector for compressed air (Type 26, 9 mm, Part Number: 697002)**
\n* **Leveg\u0151csatlakoz\u00f3 (26-os t\u00edpus, DN 8, G 1\/4″, Cikksz\u00e1m: 697003)**<\/p>\n
