Rigid Tapping<\/strong><\/td>\nSynchronizing the machine spindle rotation with the feed rate to cut threads using a tap.<\/td>\nBeneficio:<\/strong> Highest speed and accuracy for standard holes (M2-M20).
\nAplicaci\u00f3n:<\/strong> Electronic enclosures, automotive brackets.<\/td>\n<\/tr>\n
Fresado de roscas<\/strong><\/td>\nUsing a rotating multi-tooth cutter to interpolate the thread path. Can cut ID and OD threads.<\/td>\nBeneficio:<\/strong> Can thread hard metals (50+ HRC), precise size control, one tool for multiple sizes.
\nAplicaci\u00f3n:<\/strong> Large diameter aerospace parts, blind holes.<\/td>\n<\/tr>\n
Single Point Turning<\/strong><\/td>\nUsing a lathe insert to cut the thread in multiple passes.<\/td>\nBeneficio:<\/strong> Can generate any custom pitch or diameter.

Design Guidelines for Metric Threads<\/h3>\n

Thread Depth:<\/strong>
\nAvoid threading deeper than necessary. A depth of 1.5x to 2x Diameter<\/strong> is sufficient for full strength in steel. Going deeper increases the risk of tap breakage without adding strength.<\/p>\n

Blind Hole Relief:<\/strong>
\nA tap cannot cut threads all the way to the bottom of a blind hole (due to the tap chamfer). Consejo:<\/strong> Design the drill depth to be at least 1 pitch length deeper than the required full thread depth.<\/p>\n

Countersink \/ Chamfer:<\/strong>
\nAlways include a 45\u00b0 chamfer at the start of the hole. This guides the mating bolt and prevents the first thread from bulging out (mushrooming) during machining.<\/p>\n

Fine vs. Coarse Pitch:<\/strong>
\nCoarse (e.g., M10x1.5):<\/strong> Standard, less likely to cross-thread, faster assembly.
\nFine (e.g., M10x1.0):<\/strong> Stronger, better for vibration resistance, but easier to strip in soft materials.<\/p>\n<\/div>\n

Aplicaciones industriales<\/h3>\n

Global Manufacturing<\/strong>
\nMetric is the standard for virtually all industries outside the USA, including Automotive (German\/Japanese specs) and Consumer Electronics.<\/p>\n

Rob\u00f3tica<\/strong>
\nPrecision fine-pitch metric threads are used on sensor mounts and optical adjustments for fine tuning.<\/p>\n

Dispositivos m\u00e9dicos<\/strong>
\nMicro-metric threads (M1.0, M1.2) are standard in surgical implants and hearing aids.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"

Las roscas m\u00e9tricas (perfil M) son el est\u00e1ndar aceptado globalmente para la fijaci\u00f3n, definido por ISO 261 e ISO 965. Se caracterizan por un \u00e1ngulo de flanco de 60 grados y se miden por di\u00e1metro exterior y paso (en mil\u00edmetros).<\/p>\n

En Jucheng Precision, producimos millones de agujeros y ejes roscados m\u00e9tricos anualmente. Nuestra instalaci\u00f3n est\u00e1 equipada con centros de roscado Brother de alta velocidad para la producci\u00f3n r\u00e1pida de roscas peque\u00f1as (M1.6 \u2013 M12) y m\u00e1quinas de 5 ejes para el fresado de roscas complejo de roscas de gran di\u00e1metro o de metal duro. Verificamos la calidad de la rosca utilizando calibres Go\/No-Go calibrados para garantizar que cada pieza cumpla con la clase de tolerancia especificada (t\u00edpicamente 6H para roscas internas y 6g para externas).<\/p>","protected":false},"featured_media":428,"template":"","process_category":[41],"class_list":["post-427","process","type-process","status-publish","has-post-thumbnail","hentry","process_category-threading-capabilities"],"_links":{"self":[{"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/process\/427","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\/428"}],"wp:attachment":[{"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/media?parent=427"}],"wp:term":[{"taxonomy":"process_category","embeddable":true,"href":"https:\/\/www.jccncmachining.com\/es\/wp-json\/wp\/v2\/process_category?post=427"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
