DRUM ROLLER GRINDING MACHINE

CORMAK MM3146 400V

Key Features

Reinforced construction – A rigid, heavy frame minimizes vibrations and ensures stability even under intensive use.

Accurate sanding thickness adjustment – A mechanical height gauge allows precise setting of the desired processing depth.

Precisely balanced sanding drum – Made of drawn aluminum, it ensures even contact with the material and effective cooling during operation.

Versatile application – Suitable for removing old paint, lacquer, rust, as well as for smoothing and deburring.

Durable metal drive coupling – Reliable torque transfer from the motor to the sanding drum.

Working width up to 920 mm – Ability to sand wide panels in two passes.

Construction and Technology

The Cormak MM3146 stands out with its robust, industrial-grade design. The main motor, rated at 1.5 / 2.2 kW (S1/S6), combined with a reinforced 60 W feed motor, provides ample power for demanding and continuous operations. The variable-speed feed system (0–4 m/min) allows for adjustment to material type and desired finish quality.

The sanding belt (2100 × 75 mm) is driven by a high-speed drum (2800 rpm), allowing for quick and effective material removal. The sanding drum is self-cooling during operation, eliminating overheating issues. A reinforced side guide enhances parallelism and stability across the entire working width.
Precision and Efficiency

The Cormak MM3146 drum belt sander ensures consistent results thanks to its mechanical height adjustment system with a precision scale. It supports a minimum workpiece thickness of 3.5 mm and a maximum working height of 100 mm, allowing both thin boards and thick construction components to be processed. A working width of 460 mm in a single pass (or 920 mm with dual-feed operation) provides flexibility for both small and large batch production.
