The CORMAK STU75 Metal Belt Grinder is an industrial belt grinding machine designed for a wide range of metal finishing applications, including surface grinding, edge finishing, and processing cylindrical components such as pipes and tubes. Thanks to its powerful motor, two-speed belt operation, and carefully engineered working system, the STU75 provides high efficiency, precision, and reliability for everyday industrial use.

Key Features

Adjustable belt speed: 14.5 / 29 m/s – allows the grinding speed to be matched to the material type and required surface finish quality.
Quick belt and abrasive tool replacement – reduces setup times and improves workstation productivity.
Grinding head adjustable for vertical and horizontal operation – provides excellent flexibility and enables machining of various workpieces at the optimal angle.
Pipe vise with 0–30° angle adjustment – allows precise angled grinding of cylindrical components, ideal for pipe preparation before welding.
Complete set of pipe rollers for different diameters – enables quick setup for grinding pipes with diameters up to 60.3 mm.
Heavy-duty vibration-damping construction – improves grinding accuracy and operator comfort during extended operation.

Construction and Technology

The CORMAK STU75 belt grinder has been designed for versatile operation in demanding industrial environments. Equipped with a Ø200 mm rubber-coated drive wheel and a 120 × 90 mm sliding support with rollers, the machine ensures smooth belt guidance and consistent contact between the abrasive belt and the workpiece.

The integrated roller guidance system combined with a spring-loaded belt tensioning mechanism provides safe, stable, and smooth operation of the sanding belt. The rigid construction minimizes vibration, improving both machining accuracy and working comfort.

Precision and Performance

The combination of a wide 75 × 2000 mm abrasive belt and two selectable grinding speeds ensures excellent performance for both heavy stock removal and fine finishing operations. The adjustable pipe vise and dedicated roller set enable precise tube grinding with repeatable results and stable workpiece positioning.
