Description
Compared with the 12-head 4S4H4W, the 4S2H4W uses a more compact 10-head configuration with a 6250 × 1500 × 1600 mm machine size. It is a suitable option for manufacturers who need automatic four-side sanding while keeping the machine configuration and footprint more compact.
The sanding heads can be configured according to the workpiece shape and sanding requirements, making the machine suitable for sanding before painting as well as primer sanding of solid wood components.
4S2H4W vs 4S4H4W: What Is the Difference?
The main difference between the 4S2H4W and 4S4H4W is the sanding-head configuration, total power and machine length.
| Feature | 4S2H4W | 4S4H4W |
|---|---|---|
| Sanding Heads | 10 | 12 |
| Processing Width | 50–150 mm | 50–150 mm |
| Processing Thickness | 15–100 mm | 15–100 mm |
| Minimum Processing Length | 680 mm | 680 mm |
| Feeding Speed | 3–40 m/min | 3–40 m/min |
| Total Power | 29.11 kW | 33.51 kW |
| Machine Length | 6250 mm | 8800 mm |
| Main Positioning | Compact 10-head configuration | Extended 12-head configuration |
Choose the 4S2H4W when you need automatic four-side sanding with a more compact 10-head configuration and 29.11 kW total power.
Choose the 4S4H4W when your production requires a 12-head configuration, additional sanding stages and a longer machine layout.
Both models support processing of wood components within the same basic size range of 50–150 mm width, 15–100 mm thickness and 680 mm minimum length.
