Self sharpening diamond grinding disc to offer flat and fine grinding as a replacement to silicon carbide papers, reducing time and number of grinding stages. Optimised composition leads to short process times, sample flatness and superior edge retention.

SQUADRO-M and SQUADRO-H are innovative diamond grinding pads that extend fine grinding to single-micron grit sizes. They replace conventional lapping processes, achieving superior results in terms of material removal rate, surface quality, work piece geometry and tool life. SQUADRO-M and SQUADRO-H provide for an easy, clean and efficient fine grinding process.

SQUADRO grinding disc is a structured, flexible abrasive pad. The self-sharpening grinding triangles consist of a polymer matrix containing precisely graded diamond micron powder. The SQUADRO discs are available with either self-adhesive backing, magnetic backing or mounted on stainless steel carrier plates. Diameters range from 200 mm to 760 mm, in full circles or ring design. Diameters larger than 760 mm are supplied in segments.

SQUADRO grinding disc may be fitted on conventional lapping and polishing machines. To take full advantage of its grinding performance, SQUADRO should be used at circumferential speeds up to 15m/s, which is higher than typical lapping. While water is good enough for cooling, lubricants such as oil or emulsions may be used to maximize the surface finish results. The grinding disc should be dressed before its first use. In most applications, SQUADRO is self-sharpening and therefore does not need to be re-dressed.
