Description
Multi-Head Sanding for Wood Strip Processing
Automatic 4 side sanding machine is equipped with 10 sanding heads, including triangular racks, dual-purpose racks, and flying wing wheel heads, designed for sanding wooden flooring, door frames, picture frames, and other solid wood strips. Each head is controlled by variable frequency speed regulation, providing flexibility in handling different workpiece profiles. Automatic air blowing functions keep sanding belts clean, improving consistency during continuous use. Manufactured by a professional cnc router manufacturer, it illustrates how automation reduces manual adjustments. The equipment demonstrates standards expected from established woodworking cnc machine manufacturers, combining technical precision with practical performance.
Precision Adjustment with Automated Functions
The system integrates automatic compensation, variable frequency speed transmission, and pneumatic pressing for stable sanding results. Grinding spindles allow angle adjustment between 0° and 180°, meeting the needs of complex surfaces. Triangular sand racks with swing motors imitate sanding of special-shaped straight edges, while telescopic functions protect the ends of workpieces. Operators manage functions easily through a touch screen, with separated electrical boxes for simpler transport and installation. These features highlight Samdy’s role as a cnc wood router supplier committed to stability and precision. It also reflects the engineering detail valued by router cnc users managing diverse workloads.
Structural Durability with Flexible Operation
The machine body is designed with reinforced strength and stability, ensuring dependable operation during industrial-scale workloads. It supports processing widths from 50 to 150 mm, thicknesses between 15 and 100 mm, and lengths of at least 680 mm. Feeding speeds range from 3 to 40 meters per minute, supported by frequency regulation and a 4.95 kW motor. With dust outlet connections at 98 mm, safe operation is maintained throughout sanding cycles. Delivering a total power of 29.11 kW, the system combines efficiency with durability. This reflects Samdy’s expertise, also seen in 4×8 cnc router solutions, extending its capabilities to meet woodworking cnc machine requirements for heavy-duty production.
Use Scenarios
Flooring Strip Surface Preparation
The sander is designed for sanding solid wooden flooring strips, ensuring surfaces are smooth before painting or coating. With multiple head types, it can manage straight edges and detailed profiles. This makes it a practical option from a trusted cnc table router supplier. Samdy’s experience as a cnc router aluminum manufacturer strengthens its role in supporting flooring industries with consistent sanding solutions.
Door and Frame Manufacturing
Door frames and picture frames often require sanding before primer application. The combination of triangular and sponge sanding heads provides accuracy for detailed edges and corners. This versatility reflects the adaptability expected from a large cnc router manufacturer. With technology extended from its cnc router for aluminum expertise, Samdy delivers equipment suitable for workshops handling high-precision frame production.
Continuous Industrial Sanding Lines
With a conveyor speed range of 3–40 m/min, the machine supports integration into continuous sanding lines. Automatic cleaning and compensation functions reduce downtime, ensuring smooth operation in industrial settings. This aligns with the reliability users expect from advanced cnc router machines. By combining automation with robust construction, Samdy proves its capability as a cnc woodworking machine manufacturer supporting professional-scale production.
