CORMAK MM3146 400V

Main advantages of the machine

Reinforced construction – a rigid, heavy frame minimizes vibrations and ensures stability even under intensive use.
Precise grinding thickness adjustment – a mechanical height gauge allows for accurate setting of the desired processing dimension.
Precisely balanced sanding drum – made of drawn aluminum, ensures uniform contact with the workpiece and effective cooling.
Versatile applications – suitable for removing old paint, varnish, rust, as well as smoothing and deburring.
Metal drive clutch – durable and reliable torque transmission from the motor to the drum.
Working width up to 920 mm – allows sanding of wide panels in two passes.

Construction and technology

The CORMAK MM3146 model stands out with its robust, industrial-grade design. The main motor with 1.5/2.2 kW (S1/S6) power, combined with a reinforced feed drive (60 W), provides sufficient power reserve for intensive, long-term operation. The variable speed feed system (0–4 m/min) allows the pace to be adjusted to the material type and desired finish quality.

A 2100 × 75 mm sanding belt is driven by a high-speed shaft (2800 rpm), enabling quick and effective material removal. The sanding drum is self-cooling during operation, eliminating the issue of surface overheating. The side guide has been additionally reinforced, improving parallelism and sanding stability across the entire working width.

Precision and work efficiency

The CORMAK MM3146 drum belt sander guarantees consistent results thanks to its mechanical height adjustment system with a precise scale. The minimum workpiece height is 3.5 mm, and the maximum is 100 mm, allowing both thin boards and massive structural components to be processed. The working width of 460 mm in a single pass (or 920 mm with double feed) provides production flexibility even in large component series.

Applications

The CORMAK MM3146 through-feed wood sander is intended for use in:

carpentry and furniture workshops,
wood restoration studios,
metalworking shops for deburring,
production of plastic components,
finishing lines for flat surface processing.
