The CORMAK STU50 Metal Belt Sander is a precise and versatile benchtop belt grinding machine designed for efficient metal finishing in tool rooms, maintenance workshops, service centers, and production environments. The machine enables operation in both vertical and horizontal positions, while its robust construction and high-quality components ensure excellent stability and consistent machining results. Equipped with a brushless motor and variable belt speed control, the STU50 allows operators to optimize working parameters according to specific material requirements.

Key Features
Vertical and horizontal operation – quick adjustment of the grinding head position provides excellent flexibility when processing various workpieces.
Angle-adjustable belt grinder – enables precise grinding at the required angle, ideal for edge finishing and chamfering operations.
Variable belt speed control – adjustable speed range of 12–34 m/s with a clear indicator allows optimization of grinding conditions for different materials.
550 W brushless motor – provides reliable, quiet, and energy-efficient operation without the need for periodic brush replacement.
Vibration damping system – stabilizes belt tension and ensures even contact between the abrasive belt and the workpiece, improving surface finish quality.
Quick sanding belt replacement – the fast tensioning system minimizes downtime during operation.
Aluminium drive wheel and guide rollers – ensure smooth belt operation and long service life of the belt tracking system.
Construction and Technology

The CORMAK STU50 metal belt sander has been designed with a focus on compact dimensions, rigidity, and precision. A stable base and precisely bearing-mounted rollers minimize vibrations and ensure smooth, accurate belt tracking.

Adjustable steel workpiece supports allow precise positioning and firm support of the material against the sanding belt, which is essential when working with components requiring high accuracy. All belt guards comply with CE safety standards, ensuring reliable protection for the operator during use.

Precision and Performance

This benchtop belt grinder provides efficient and precise removal of excess material from flat surfaces and edges. Thanks to the variable belt speed adjustment, the operator can adapt grinding parameters to the hardness and structure of the processed metal, resulting in improved surface quality and extended abrasive belt life.

With a low weight of only 20 kg and compact dimensions, the STU50 is an excellent solution for workshops with limited working space while still providing professional grinding performance.
