CORMAK MM3156C 400V Drum Sander for Wood

The CORMAK MM3156C 400V is a technologically advanced conveyor drum sander designed for precise and repeatable surface finishing of flat workpieces. Thanks to its robust construction, smooth operation, and interchangeable drum system, the machine is ideal for sanding solid wood, veneers, furniture boards, as well as metals and plastics. The MM3156C is intended for continuous operation in production facilities and woodworking workshops where precision, consistency, and reliability are essential.

Key Advantages

Interchangeable sanding drums – allows quick adaptation to different materials such as wood, metal, and veneered panels.
Dual drum speed– 750/1440 RPM enables optimal adjustment to the type of surface and required sanding aggressiveness.
High precision– a rigid frame with a cast-iron arm and hardened guideways ensures accurate shaft guidance and consistent finishing quality.
Mechanical thickness gauge– allows precise setting and monitoring of machining parameters.
Self-cooling aluminum drum– accurately balanced and resistant to overheating during continuous operation.
Optional brush drums– the machine can be converted into a wood aging/distressing sander with additional equipment.

Construction and Technology

The CORMAK MM3156C drum sander has been developed for industrial applications. The reinforced sanding shaft design, high-quality bronze bushings, and conveyor belt tensioners ensure long service life and stable, backlash-free operation. A reinforced coupling provides efficient torque transmission from the 1.5 kW motor to the working shaft.

The machine features continuously variable feed speed adjustment from 0 to 3 m/min, allowing the operator to match the feed rate to the material type and sanding requirements.

The table guidance system, equipped with hardened guide rails and a cast-iron body, effectively minimizes vibration and increases the rigidity of the entire structure. With a working width of 560 mm and a maximum workpiece height of 80 mm, the MM3156C is an optimal solution for both high-volume production and precision custom work.
