DRUM ROLLER GRINDING MACHINE

CORMAK MM3146 400V

The CORMAK MM3146 400V drum sander is an efficient single-unit machine designed for precision sanding of flat surfaces made of solid wood, furniture boards, metal elements, and plastics. Thanks to its robust construction, precise guiding system, and large-diameter sanding drum, the machine provides uniform surface finishing with high working efficiency. It is an ideal solution for production plants, woodworking workshops, and companies specializing 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 provides uniform contact with the workpiece and effective heat dissipation.
Universal application – suitable for removing old paint, varnish, rust, as well as for smoothing and deburring surfaces.
Metal drum drive coupling – durable and reliable torque transmission from the motor to the sanding drum.
Working width up to 920 mm – allows sanding of wide panels with two passes.
Design and technology

The CORMAK MM3146 features a solid industrial construction. The main motor with a power rating of 1.5/2.2 kW (S1/S6), combined with a reinforced feed drive (60 W), provides sufficient power reserves for intensive, long-term operation. The variable feed speed system (0–4 m/min) allows the operator to adjust the working speed according to the material type and required finishing quality.

The 2100 × 75 mm sanding belt drives a high-speed drum (2800 rpm), enabling fast and effective material removal. The sanding drum is self-cooling 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 machining of both thin panels and solid structural elements.
