Cast Iron Lapping Plate

Cast Iron Lapping Plate, also known as grinding platform or scraping grinding plate, is a precision grinding tool made of gray cast iron (HT200-300) or ductile iron. It belongs to the category of cast iron inspection plate and is mainly used in the fields of measuring tool manufacturing, high-precision mechanical parts processing, optical instrument manufacturing, and ultra precision workpiece inspection. Its specifications cover from 100 × 100mm to 4000 × 8000mm, and its accuracy level is classified according to national standards such as JB/T 7974-2000, with a maximum flatness of 0.005mm.

This product is divided into slotted type and embedded sand type: slotted type has a cross or V-shaped groove on the working face, suitable for wet grinding and rough machining; The surface of the embedded sand mold is uniformly embedded with diamond abrasive, suitable for dry grinding and precision machining, and can make the surface roughness of the workpiece reach Ra0.01 μ m. By using the three plate mutual grinding method or the mother child plate pressing method for processing, the flatness and abrasive distribution are ensured to be uniform, with a hardness of HB170-240, which combines high wear resistance and cutting performance. When grinding, it is necessary to use grinding agents and abrasives with matching particle size. After use, regular cleaning and maintenance are required to maintain accuracy.

Classification of Cast Iron Lapping Plates: Cast Iron Lapping Plates can be divided into slotted Cast Iron Lapping Plates and sand embedded Cast Iron Lapping Plates.

(1) Slotted Cast Iron Lapping Plate is used for wet grinding. In order to scrape off excess abrasive, ensure even contact between the workpiece and the flat plate, and improve the flatness of the processed workpiece, the heat generated by grinding is easily dissipated. This type of flat plate has intersecting square grooves or 60 degree V-shaped grooves on the working surface, which is also named after it. It is mainly suitable for rough machining.

(2) As the name suggests, the sand embedded Cast Iron Lapping Plate is used for dry grinding, and its abrasive is diamond sand in the surface layer, which is suitable for precision machining. The surface roughness of the workpiece can reach 0.025um, with a maximum of 0.01um. It is divided into rectangular shapes (100 * 200, 200 * 300, 300 * 400, 400 * 500, 400 * 600, 500 * 600, 500 * 800, 600 * 800, 600 * 900, 1000 * 750), square shapes (200 * 200, 300 * 300, 400 * 400, 500 * 500, 1000 * 1000), and circular shapes (￠ 200~~￠ 500)

The uses of Cast Iron Lapping Plates include the manufacturing and repair of measuring tools, grinding of workpieces, production of high-precision mechanical parts, processing of optical instruments, and inspection of ultra precision workpieces.
