This Blohm HFS512 is a used surface grinding machine — sometimes referred to as a flat grinder — designed to produce precise, flat, and smooth finishes on metal workpieces through the action of a rotating abrasive wheel. Surface grinders are core equipment in toolmaking, die and mould shops, and general precision engineering, where tight tolerances on flatness and surface finish are essential. Blohm is a well-regarded German manufacturer with a long history of producing high-quality surface and profile grinding machines for the metalworking and tooling industries.
Two units are available from this listing, both located in Portugal and offered in used condition. The machines are equipped with an electromagnetic chuck measuring 750 × 300 mm, and a magnetic plate of 1,200 × 500 mm is also referenced, suggesting the availability of an extended workholding surface. A further magnetic board surface of 600 × 200 mm is noted among the specifications. The table dimensions are given as 750 × 400 mm and 750 × 500 mm across different references in the seller's data, with a larger table surface of 2,000 × 500 mm also noted.
The grinding length reaches 1,200 mm, with a maximum grinding width of 500 mm and a maximum part height of 400 mm. The maximum distance from the table surface to the centre of the grinding spindle is 495 mm, while the maximum grinding height is stated as 625 mm. Maximum grinding length figures of 600 mm and 750 mm are both cited in the seller's notes. Two grinding wheel sizes are listed: 250 × 25 × 51 mm and 400 × 80 mm, with wheel speed noted at 1,500 rpm.
Table speed ranges from 2 to 20 m/min in one reference and up to 2–300 m/min in another. Electrical cross feed is rated at 1.20 m/min, while intermittent cross feed ranges from 2 to 60 m/min. Total power requirement is 11 kW. The overall machine dimensions are 3,100 × 2,400 × 2,200 mm, and machine weight is stated at approximately 6.3 tonnes in the primary references, with a figure of 3,500 kg also appearing in the seller's notes.
