La m\u00e1quina SX2872 cubre una gama de bridas desde 711 mm (28\u201d) de di\u00e1metro interno hasta 1829 mm (72\u201d) de di\u00e1metro externo. La plataforma giratoria incorpora dos motores neum\u00e1ticos de 1,7 kW (2,3 hp), que est\u00e1n dise\u00f1ados para compensar el contragolpe que normalmente se encuentra en los sistemas de transmisi\u00f3n por engranajes rectos. La base de montaje del orificio tiene cuatro patas seccionales que aseguran un ajuste preciso mientras mantienen la rigidez adecuada, incluso cuando est\u00e1n completamente extendidas. El dise\u00f1o modular tambi\u00e9n hace que el SX2872 sea f\u00e1cil de configurar con cualquiera de los kits de montaje de di\u00e1metro exterior y placa de tubo opcionales, que est\u00e1n disponibles a pedido. Compacto, liviano, excelente para el mecanizado en el sitio<\/p>\n<p>Base de montaje<\/p>\n<p>El conjunto de montaje permite instalar la m\u00e1quina en el centro de cualquier brida de 711 mm (28&quot;) a 1829 mm (72&quot;) de di\u00e1metro. Consiste en un cuerpo cruciforme provisto de cuatro conjuntos de mordazas de sujeci\u00f3n ajustables. La base de montaje se instala y alinea antes de la instalaci\u00f3n de la plataforma giratoria.<\/p>\n<p>Ensamblaje de tocadiscos<\/p>\n<p>Esto proporciona un soporte r\u00edgido para los motores neum\u00e1ticos, la caja de engranajes y el conjunto de superficie. La parte superior del conjunto proporciona el movimiento de rotaci\u00f3n para la superficie, mientras que la parte inferior permanece estacionaria, mantenida en posici\u00f3n por el conjunto de la base de montaje.<\/p>\n<p>Brazo de corte<\/p>\n<p>Este se monta en el conjunto de la plataforma giratoria y proporciona una estructura r\u00edgida a la que se fija el poste de herramientas. La alimentaci\u00f3n de entrada y salida es proporcionada por un tornillo de avance, accionado por el engranaje de salida de la caja de engranajes. La velocidad de alimentaci\u00f3n se selecciona en la caja de cambios. Si el material, las herramientas y las condiciones lo permiten, el conjunto del brazo de corte puede lograr cortes de una profundidad m\u00e1xima de 2 mm (0,079&quot;) sin orificios de brida y de 0,5 mm (0,02&quot;) con orificios de brida<\/p>\n<p>Disposici\u00f3n de accionamiento<\/p>\n<p>Esta m\u00e1quina es accionada por dos unidades de motor neum\u00e1tico, montadas directamente en la corona dentada, que a su vez est\u00e1 montada en el cojinete principal. El uso de dos motores permite reducir la altura total de la m\u00e1quina.<\/p>\n<p>Caja de engranajes de alimentaci\u00f3n<\/p>\n<p>La caja de engranajes de transmisi\u00f3n est\u00e1 montada en el conjunto de la plataforma giratoria y proporciona una variedad de avances de corte para diferentes aplicaciones. La entrada de transmisi\u00f3n a la caja de cambios se deriva del engranaje de transferencia del m\u00e1stil. La caja de cambios proporciona cuatro velocidades de alimentaci\u00f3n diferentes seleccionadas por un selector de empujar\/tirar. La traves\u00eda tambi\u00e9n se activa mediante un selector de empujar\/jalar, que proporciona traves\u00eda IN, traves\u00eda OUT y punto muerto. La posici\u00f3n neutra N se usa para posicionar manualmente el poste de la herramienta.

The SX2872 machine covers a range of flanges from 711mm (28\u201d) internal diameter to 1829mm (72\u201d) external diameter. The turntable incorporates twin 1.7kW (2.3hp) pneumatic motors, which are designed to compensate for the backlash normally found in spur gear drive systems. The bore mounting base has four sectional legs that ensure precise adjustment while maintaining proper rigidity, even when fully extended. The modular design also makes the SX2872 easy to set up with any of the optional tube sheet and outside diameter mounting kits, which are available on request. Compact, lightweight great for onsite machining  Mounting Base  The mounting assembly enables the machine to be installed in the centre of any flange from 711mm (28\u201d) to 1829mm (72\u201d) in diameter. It consists of a cruciform body provided with four adjustable clamping jaw assemblies. The mounting base is installed and aligned prior to the turntable installation.  Turntable Assembly  This provides a rigid support for the air motors, gearbox and surfacing assembly. The upper part of the assembly provides the rotational movement for surfacing, whilst the lower part remains stationary, held in position by the mounting base assembly.  Cutting Arm  This is mounted on the turntable assembly and provides a rigid structure to which the toolpost is fixed. Feed in and out is provided by a lead screw, driven by the gearbox output gear. Feed rate is selected at the gearbox. Material, tooling and conditions permitting, the cutting arm assembly can achieve cuts to a maximum depth of 2mm (0.079\u201d) without flange holes and 0.5mm (0.02\u201d) with flange holes  Drive Arrangment  This machine is driven by two pneumatic motor units, mounted directly into the ring gear, which in turn is mounted on the main bearing. The use of two motors enables the overall machine height to be reduced.  Feed Gearbox  The drive gearbox is mounted on the turntable assembly providing a variety of cutting feeds for different applications. Drive input to the gearbox is derived from the mast transfer gear. The gearbox provides four different feed rates selected by a push\/pull selector. Traverse is also engaged by a push\/pull selector, which gives traverse IN, traverse OUT and neutral. The neutral N position is used for manually positioning the tool post.out the torque and also acts as a backlash eliminator and cushion drive.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/mactecheurope.co.uk\/es\/catalogue\/silk-sx28-72\/\" \/>\n<meta property=\"og:site_name\" content=\"Machines -
