Hard alloy plate


твердосплавные пластины Carbide insert – is replaceable cutters made ​​of tool steel that can handle different materials . By the method of installation are divided into two groups: Replaceable insert – manually attached to the populated, (cutters, arbor , cutter body), which provides the highest precision fastening. The clear advantage of using these plates, it is reusable holder and quick accessory changes , eliminating the regrinding and soldering , forming the front edge of the stage to the production of tungsten carbide insert. Brazed tips – attached by soldering with solder on tool set followed by grinding, ensuring the correct location of each plate and tooling , including their geometrical parameters . The plates are compressed under high pressure based on the weight of the powder homogenized titanium carbide , tungsten carbide , tantalum carbide or their possible combinations. Sintering is performed at a high temperature to further machining. Plates feature a high hardness (HRA 82-92) complete with high abrasion resistance including stored at high temperatures up to 1150 ° C. Depending on the type of material used , and reduces the chip Hardmetals classified according to international standards ISO T513. The plates are divided into three groups: F , M , C. When choosing an alloy grade , consider cutting conditions , technological capabilities and technology type of material . The lower the index notation of the application , the lower the strength of cemented carbide cutting depth in the processing and supply permissible , but higher wear resistance and permissible cutting speed. F – Cast iron, chilled cast iron, ductile iron, giving a chip fracture, non-ferrous metals, plastics, wood. M – Steel, cast steel, manganese steel, austenitic stainless steel, free-cutting steel, alloy cast iron, ductile cast iron. C – Steel, cast steel, corrosion-resistant steel, ductile iron, chipping.
