The Alpa RTL700 E is a used machining center — also commonly referred to as a surface grinder — currently located in Portugal and available in a quantity of two units. Surface grinders are precision grinding machines used to produce smooth, flat finishes on workpiece surfaces by passing them beneath a rotating abrasive wheel, making them a staple in metalworking, toolmaking, and precision engineering workshops. Alpa is a recognised Italian manufacturer with a long-standing reputation for building high-precision surface and cylindrical grinding machines, primarily serving the metalworking and industrial manufacturing sectors.
The table on this machine measures 700 × 500 mm (approximately 6 × 16 inches in imperial terms), providing a solid working area for a range of workpiece sizes. The maximum longitudinal stroke is reported at between 800 mm and 900 mm, and the maximum transverse stroke is approximately 550 mm, giving the machine a broad working envelope suited to medium-sized components. The distance between the table surface and the grinding wheel axis is approximately 620 mm.
The grinding wheel fitted to this machine measures approximately 400 × 50 × 127 mm (roughly 8 inches in diameter by 2 inches wide, with a bore of approximately 4 and three-quarter inches), and the spindle runs at 3,480 rpm. The grinding wheel motor delivers approximately 12 HP, equivalent to around 9 kW, providing adequate power for demanding surface grinding operations. The machine is capable of grinding lengths of up to 700–750 mm and grinding widths of up to 500 mm.
The estimated machine weight falls between 3,100 kg and 3,800 kg, reflecting a robust, heavy-duty construction typical of precision grinding equipment in this class. As noted by the seller, the figures presented are approximate, and all specifications should be verified by physically inspecting the machine prior to purchase.
