Condition: new, Year of construction: 2026, functionality: fully functional, CORMAK MM3146 230V Drum Roller Sander for Wood is an efficient, single-unit sanding machine designed for finishing flat surfaces made of solid wood, furniture boards, metal components, and plastics. Thanks to its robust construction, precise guidance system, and large-diameter sanding drum, the machine provides uniform surface finishing with high working efficiency. It is an ideal solution for production facilities, woodworking workshops, and companies involved in renovation and finishing processes. Main advantages of the machine Reinforced construction – a rigid, heavy-duty frame minimizes vibrations and ensures stability even during intensive operation. Precise sanding thickness adjustment – a mechanical height gauge allows accurate setting of the required machining dimension. Precisely balanced sanding drum – made of drawn aluminum, it ensures even contact with the workpiece and effective cooling. Universal application – suitable for removing old paint, varnish, corrosion, as well as smoothing and deburring surfaces. Metal drive coupling – provides durable and reliable transmission of torque from the motor to the sanding drum. Working width up to 920 mm – allows sanding of wide panels using a double-pass method. Construction and technology The CORMAK MM3146 stands out with its solid industrial construction. The 1.5/2.2 kW (S1/S6) main motor, combined with a reinforced 60 W feed drive, provides sufficient power reserve for intensive, long-term operation. The variable feed speed system (0–4 m/min) allows adjustment of the working pace depending on the material type and required surface quality. The sanding belt measuring 2100 × 75 mm drives a high-speed roller (2800 rpm), enabling fast and effective material removal. The aluminum sanding drum cools itself during operation, eliminating the risk of overheating the work surface. The side guide has been additionally reinforced, improving parallel alignment and sanding stability across the entire working width. Precision and working efficiency The CORMAK MM3146 drum sander guarantees repeatable results thanks to its mechanical height adjustment system with a precise scale. The minimum workpiece thickness is 3.5 mm, while the maximum is 100 mm, allowing the processing of both thin panels and solid structural elements. The working width of 460 mm in a single pass (or 920 mm with double guiding) provides production flexibility, even when processing larger batches of components.

Condition: new, Year of construction: 2026, 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. Iedpjvugf Rofx Ad Istl 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.
