Spark Erosion for PCD Machining



Polycrystalline tools are an integral part of aluminum machining in the automobile and accessories industry, in wood and composite machining in the furniture, flooring, and laminate manufacturing industries, as well as in plastic and circuit board manufacturing and other industries.


At LACH DIAMOND, a separate machine engineering department developed from discovering the many possibilities for spark erosion machining of PCD – at first only for on-site use.


Since the mid-80s, so-called LACH DIAMOND spark erosion machines, type EDG-plus were the core business idea for many start-ups who aimed to get into tool manufacturing and servicing of diamond tools for the wood and plastic industry  – at the beginning mostly in Germany, USA and Israel.


At IMTS in Chicago, LACH DIAMOND will inform you about the universal sharpening machine Dia-2200-mini, compact and user-friendly for servicing and producing diamond tools in particular, up to a maximum of ø 480 mm for wood and plastic manufacturing – diamond end mills, scoring saws, jointing cutters, profiling tools, saw blades – from individual production to serial production, tooth-by-tooth in automated processes.


Since EMO 2017, the “mini” model is available as a special edition, named »Dia-contour-profiled«, for highly precise profiling (convex and concave) of metal-bond diamond and CBN grinding wheels for the serial production of carbide, HSS and ceramic tools.
