Es esencial para piezas que requieren un dimensionado preciso del agujero, una redondez perfecta y un acabado superficial de alta calidad que el taladrado o el mandrinado no pueden lograr, especialmente en materiales endurecidos.<\/p>\n En Jucheng Precision, utilizamos rectificadoras universales capaces de realizar tanto el rectificado interior como el exterior en una sola configuraci\u00f3n. Esto garantiza una concentricidad absoluta entre el agujero interior y el di\u00e1metro exterior. Nos especializamos en el rectificado de casquillos de acero endurecido, pistas de rodamientos y pinzas hasta tolerancias de 0,005 mm, corrigiendo cualquier distorsi\u00f3n por tratamiento t\u00e9rmico para garantizar un ajuste perfecto.<\/p>","protected":false},"featured_media":426,"template":"","process_category":[40],"class_list":["post-425","process","type-process","status-publish","has-post-thumbnail","hentry","process_category-precision-grinding"],"_links":{"self":[{"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/process\/425","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/process"}],"about":[{"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/types\/process"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/media\/426"}],"wp:attachment":[{"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/media?parent=425"}],"wp:term":[{"taxonomy":"process_category","embeddable":true,"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/process_category?post=425"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n\n

\nGrinding a blind hole (a hole that doesn’t go all the way through) is difficult because the wheel cannot touch the bottom. Consejo:<\/strong> Always include a “grinding relief” or undercut at the bottom of the bore so the wheel can over-travel slightly.<\/p>\n
\nThin-walled parts are very difficult to ID grind. The pressure of the chuck jaws can deform the part out-of-round. Consejo:<\/strong> Maintain sufficient wall thickness or design a flange for clamping.<\/p>\n
\nDeep, small holes require long, thin grinding quills which are prone to vibration (chatter). Consejo:<\/strong> Avoid designing ground holes deeper than 5x their diameter.<\/p>\n
\nWhenever possible, design through-holes. This allows the coolant to flush chips out effectively and allows the wheel to pass completely through for a uniform cylinder.<\/p>\n<\/div>\nAplicaciones industriales<\/h3>\n
\nGrinding the inner races of roller bearings to handle high rotational speeds and loads without failure.<\/p>\n
\nThe central bore of transmission gears is ground to ensure it fits perfectly onto the shaft, preventing wobble and noise.<\/p>\n
\nHydraulic cylinder bodies are ID ground (or honed) to create a smooth surface for the piston seal, preventing leakage.<\/p>\n
\nCollets and tool holders require ID grinding to ensure they hold cutting tools with zero runout.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
