DRUM SANDER

CORMAK MM3156C 400V

CORMAK MM3156C 400V Drum Sander for Wood is a technologically advanced through-feed sander designed for precise and repeatable machining of flat surfaces. With its robust construction, smooth operation, and interchangeable sanding drums, this machine excels at sanding solid wood, veneers, furniture panels, as well as metals and plastics. The MM3156C model is intended for continuous operation in production facilities and woodworking shops where precision, consistency, and reliability are paramount.

Key Advantages

- Interchangeable sanding drums – quick adaptation to various materials: wood, metal, veneered panels.
- Dual drum speed – 750/1440 rpm allows parameters to be adjusted according to the type and roughness of the workpiece.
- High accuracy – the rigid frame with a cast iron arm and hardened guides ensures precise spindle guidance and repeatable machining quality.
- Mechanical thickness gauge – allows for precise setting and control of processing parameters.
- Aluminum self-cooling drum – precisely balanced and resistant to overheating during continuous operation.
- Option to install brush drums – as an additional feature, the machine can be converted into a wood ageing sander.

Construction and Technology

The CORMAK MM3156C drum sander is developed for industrial applications. The reinforced sanding drum construction, high-quality bronze bushings, and conveyor belt tensioners guarantee long service life and stable, backlash-free performance. The enhanced clutch ensures efficient torque transfer from the 1.5 kW motor to the working spindle. The machine features stepless feed rate adjustment from 0 to 3 m/min, allowing users to adapt the work pace to specific materials and sanding intensity.

The table guidance system, equipped with hardened guides and a cast iron bed, effectively eliminates vibrations and increases the overall structure’s rigidity. With a working width of 560 mm and a maximum workpiece height of 80 mm, this sander is an optimal solution for both batch production and precise one-off tasks.

Precision and Performance

The CORMAK MM3156C through-feed drum sander delivers industrial-grade precision thanks to a design optimized for rigidity, guidance, and vibration dampening. The minimum workpiece thickness is 3.5 mm with a minimum length of 600 mm. The sanding drum, sized 133 × 560 mm, enables accurate and uniform removal of material in layers up to 0.5 mm. An integrated Ø100 mm extraction port allows for dust collection system connection, maintaining a clean workspace.
