CORMAK SM75

CORMAK SM75 Belt Grinder is a high-performance industrial metal belt grinding machine designed for precise, fast, and safe grinding of steel and metal components. Thanks to its two-speed operation and wide vibration-damping base, the SM75 stationary belt grinder is ideal for single-piece production, series production, and workshop applications requiring a large contact surface with the material. Its simple design ensures easy operation, while the robust construction guarantees long service life even under intensive working conditions.

Main advantages of the machine
Two-speed abrasive belt operation – 14.5 / 29 m/s – allows adjustment of the working mode to the type of material and the required process (rough grinding or precision finishing).
3 kW / 400 V motor – ensures smooth and stable operation even under heavy loads.
Large grinding surface – a 75 mm wide belt and a contact wheel measuring 250 × 150 mm enable efficient work with large components.
Belt grinder with quick belt tensioning system – the spring-loaded mechanism automatically maintains the correct belt tension, improving operator comfort.
Adjustable grinding head angle – enables quick adaptation of the machine setup to specific machining tasks.
Stable, vibration-free construction – the wide cast-iron base eliminates vibrations and improves the quality of the finished surface.
Two dust extraction ports – efficiently remove grinding dust, improving workplace safety and cleanliness.
Design and technology

The CORMAK SM75 metal belt grinder is built on a highly rigid frame construction that ensures stability and precise belt tracking even under maximum pressure. The high machine weight (72 kg) and low center of gravity further reduce vibrations during operation.

The belt tensioning and guiding system, based on bearing-mounted rollers, allows quick replacement of abrasive belts without the need for additional tools. The graphite coating under the belt reduces friction, improving both grinding quality and abrasive belt durability.

Precision and work efficiency

The two-speed belt adjustment allows the operator to match the grinding speed to the type of workpiece and the required surface finish. The CORMAK SM75 stationary belt grinder is suitable for both aggressive material removal and precise edge finishing.

The integrated dust extraction system and ergonomic work table provide a clean working environment and stable support for the processed material.
