DRUM SANDER

CORMAK MM3146 400V

Main advantages of the machine

- Reinforced construction – a rigid, heavy-duty frame minimizes vibrations and ensures stability even during intensive operation.
- Precise grinding thickness adjustment – a mechanical height gauge allows for accurate setting of the required processing dimension.
- Precisely balanced sanding drum – made of drawn aluminum, ensures uniform contact with the workpiece and efficient cooling.
- Versatile application – for removal of old paint, varnish, rust, as well as for smoothing and deburring.
- Metal drive clutch – durable and reliable torque transfer from the motor to the drum.
- Working width up to 920 mm – enables sanding of wide panels in two passes.

Construction and technology

The CORMAK MM3146 model stands out due to its robust, industrial-grade design. 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 reserve for intensive, continuous use. The variable speed feed system (0–4 m/min) allows adjustment of processing speed according to the material type and desired surface finish quality.

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

Precision and performance

The CORMAK MM3146 drum belt sander guarantees repeatable results thanks to its mechanical height adjustment system with precise scaling. The minimum workpiece thickness is 3.5 mm, and the maximum is 100 mm, allowing for processing both thin boards and heavy structural elements. The working width is 460 mm in a single pass (or 920 mm with double feed), ensuring production flexibility even for large series of components.

Application

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

- carpentry and furniture workshops,
- wood restoration studios,
- metal workshops for deburring,
- production of plastic components,
- technological lines for finishing flat surfaces.
