This Alpa RT 4000 surface grinding machine is designed for precision grinding with a large working area. It features a table measuring 4000 mm in length and 400 mm in width, supporting a maximum grinding length of 4000 mm. The machine offers a maximum longitudinal travel of 4200 mm and a maximum cross travel of 600 mm, allowing for versatile grinding operations. The maximum grinding width is 550 mm, and the distance from the wheel center to the table can reach up to 700 mm.
The grinding wheel has dimensions of 400 mm in diameter, 50 mm in width, and a bore size of 127 mm. It operates at a maximum spindle speed of 1400 rpm, powered by a 12 hp motor. The machine weighs approximately 13,000 kg, reflecting its robust build suitable for heavy-duty grinding tasks.
This model is manually operated and does not include CNC capabilities. The machine features a long flat bed with T-slots for secure workpiece mounting. The grinding head assembly includes control knobs and a handwheel for manual adjustments. Pipes and cables are attached to the grinding head to support its operation.
The machine shows signs of wear consistent with regular use, including some paint chipping and dirt on the body and metal surfaces. There are visible wear marks and some surface rust or dirt accumulation on the grinding head. The overall condition indicates a well-used machine that has been maintained in a workshop environment. A red tool cabinet is present in the vicinity, suggesting the machine is part of an active workspace.
This Alpa RT 4000 is suitable for users seeking a manual surface grinding machine with a large working area and substantial grinding capacity.
