Description
Multi-Head Sanding for Complex Profiles
12 heads automatic linear sander machine features 12 sanding heads designed for professional sanding of solid wooden strips, flooring, door frames, and picture frames. The combination of triangular sand racks, dual-purpose sand racks, and flying wing wheel heads provides comprehensive processing flexibility. Each grinding head is controlled by variable frequency speed regulation, ensuring precise sanding adjustments for different shapes and profiles. Developed by an experienced cnc router manufacturer, the system highlights how automation improves consistency. It reflects the standards upheld by leading woodworking cnc machine manufacturers, offering reliable sanding for both primer preparation and surface finishing.
Precision Adjustment with Automated Control
The machine integrates automatic compensation, pneumatic material pressing, and frequency-regulated transmission to keep sanding uniform. Spindles can adjust angles between 0° and 180°, supporting a wide range of working requirements. Sponge sanding heads allow compatibility with brush rollers, octagonal sand, polishing wheels, and other abrasives for versatile finishing. Operators benefit from touch-screen control and separated electrical box design for easy transport and management.
Heavy-Duty Build for Continuous Operation
Built with a strong machine body and reinforced structure, the equipment ensures durability during industrial workloads. Each sanding belt includes automatic swing and telescopic functions, protecting the head and tail of the workpiece. A dust outlet system with 98mm diameter connections supports safe operation. The total installed power of 33.51kW delivers consistent performance, while a conveyor speed range of 3–40 m/min provides flexibility in production.
