Condition: new, Year of construction: 2026, The CORMAK PSM150 belt grinder is an advanced metal belt sanding machine designed for efficient and precise grinding of large flat surfaces as well as hard-to-reach welds close to the floor. Its construction has been optimized for ergonomics, stability, and ease of operation, making it an indispensable solution for professional industrial plants, metalworking workshops, and welding facilities. Main advantages of the machine High grinding efficiency – ideal for processing sheet metal, weld seams, and surfaces near the floor. Metal belt grinder with a large contact wheel 195 × 150 mm – provides a large contact area and stable operation. Adjustable depth stop – enables precise adjustment of grinding parameters to suit the workpiece. Large working surface 150 × 450 mm – effective finishing of large and flat components. Two belt speeds – 15 and 30 m/s – allows selection of the appropriate working speed depending on the application. Low machine weight (85 kg) – ensures mobility and easy transport within the facility. Design and technology The CORMAK PSM150 is a stationary belt grinder designed for sanding large and heavy components that cannot be processed on standard work tables due to their size. Its ergonomic design allows the operator to maneuver the machine directly over the workpiece. The drive roller and the 150 mm wide contact wheel enable efficient work on wide weld seams and surfaces. The adjustable working height range of 475–1240 mm allows the machine to be adapted to individual working conditions. Ljdpevu Unmsfx Aazort Precision and working efficiency A 2.8 kW motor and a two-speed drive system ensure high grinding performance while maintaining precision. The CORMAK PSM150 metal belt grinder is suitable for processing components made of carbon steel, stainless steel, and aluminum. The stable construction minimizes vibrations, while the belt guidance system ensures accurate tracking along the entire working length. Applications The PSM150 model is an ideal solution for: welding shops and steel construction plants, manufacturers of railings, handrails, and large sheet metal components, companies involved in renovation and grinding of metal surfaces, maintenance and repair departments, stainless steel and aluminum processing facilities.
