Used PROTH PSGS-3060BH SURFACE GRINDER for sale — Surface Grinders

The PROTH PSGS-3060BH is a precision horizontal reciprocating surface grinder engineered for demanding industrial surface finishing tasks. This machine features a generous grinding surface of the table measuring 300 x 600 mm, making it suitable for processing medium-sized components with high geometric accuracy. The mechanical architecture supports a maximum travel of 340 mm on the cross-axis and 700 mm on the longitudinal axis. With a spindle center height from the table of 600 mm and a maximum height of 422 mm from the table top to the bottom of a standard wheel, operators can comfortably accommodate a wide range of workpiece profiles and fixtures. From a performance perspective, the machine is driven by a main spindle motor rated at 3.7 kW / 3.73 kW, rotating at 1500 RPM on 50 Hz and 1800 RPM on 60 Hz systems. The grinding wheel size is standardized at 355 x 38 x 127 mm (Outer Diameter x Width x Inner Diameter) to ensure stable cutting actions. The hydraulic system, powered by a 0.75 kW / 0.75 kW motor, delivers continuous hydraulic table speeds ranging from 1 to 25 (0.3 to 25) m/min. This allows production engineers to fine-tune traverse rates depending on the material and surface finish requirements. Cross-feed capabilities are highly adjustable, offering intermittent feed rates between 0.1 and 10 mm per feed, alongside a continuous cross-feed of 1000 mm/min. Manual cross-axis movements are controlled via a handwheel providing 4 mm of travel per revolution with increments of 0.02 mm per division. For vertical adjustments, the machine delivers a hand feed of 1 mm per revolution with precise increments of 0.005 mm per division, facilitating close-tolerance final passes. Vertical rapid traverse is also supported as an option at a rate of 200 to 220 mm/min. Built for stability, the unit has a net weight of 1900 kg and a gross weight of 2500 kg, housed within physical dimensions of 1.95 x 1.95 x 1.90 meters (L x W x H) to ensure a rigid footprint during heavy grinding cycles. This system is typically utilized in toolrooms, mold making, and precision manufacturing shops for grinding flat surfaces of steel castings, plates, and machined components. This machine is imported, inspected, and made available directly through Corel Machinery in India.
