Requisitos de instalación para guías lineales en plataformas de mármol
En el proceso de producción industrial, las plataformas de mármol son un tipo de superficie de referencia de medición de alta precisión, y sus características físicas únicas les confieren ventajas significativas en el campo de la medición de precisión.
En algunas industrias, es necesario instalar guías de mármol, principalmente dividido en dos categorías: una es perforar agujeros en la plataforma de mármol e instalar guías para probar la rectitud y planitud de los productos. La segunda categoría es a las guías en los componentes de mármol no estándar para lograr el propósito de diseño de componentes. Entonces, ¿cuáles son las precauciones cuando instalan guías?
Precauciones para la instalación de guías
1 Mantenga limpia y ordenada la plataforma de mármol (la zona donde está instalada la guía). Para limpiarla, vierta alcohol en un paño sin polvo y limpie la superficie plana. Después de limpiar con el paño, utilice una mano seca y limpia para arrastrarlo ligeramente por la superficie de la plataforma. Si hay una sensación de obstrucción, es necesario raspar con un; si es suave y sin obstrucciones, entonces el primer paso se ha completado.
- Saque la guía (utilice guantes de goma para evitar que la guía se oxide, utilice un paño sin polvo con alcohol para limpiar la superficie de instalación de la guía y elimine el aceite de la guía. Después de la limpieza, coloque la guía en el área de instalación de la plataforma de mármol alinear las posiciones de los agujeros.
- Alinee las posiciones de los orificios de la guía y los orificios de instalación de la canica, coloque el nivel de la canica junto a la guía (la distancia debe ser cercana, no lejana) y hágalo aproximadamente paralelo a la guía. Si la canica tiene una superficie de referencia para la instalación, se puede omitir el nivel de la canica y utilizar la superficie de referencia de la propia canica o componente para ajustar la guía.
- Fije la posición del primer orificio de la guía, dejando espacio para el ajuste hacia arriba, hacia abajo, hacia la izquierda y hacia la derecha. un indicador de palanca de dial magnético (no se recomienda utilizar otros tipos de indicadores) en el bloque de deslizamiento de la guía y, a continuación, ajuste el nivel de mármol para garantizar la instalación de la guía (si tiene alguna duda, consulte a nuestro personal profesional).
- Endereza la guía.
Debe tenerse en cuenta que en este estado, no hay problema en utilizar esta guía para medir la rectitud relativa de la pieza de trabajo, pero no es precisa para medir el plano de la pieza de trabajo en la dirección arriba-abajo. Esto se debe a que hay un error en la ondulación en forma de Y de la propia guía, y el paralelismo de marcha después debe confirmarse con el fabricante de la guía. Si la guía se selecciona como una guía importada de ultraprecisión, su paralelismo de marcha es suficientemente pequeño, y este método también se puede utilizar para medir la planitud de la pieza de trabajo.
FAQ
1. What is the maximum size of granite workbench that can be processed??
Normally, we have two types of granite platforms: regular granite platforms (usually available in stock) and customized granite platforms (customized according to customer needs, with delivery time). However, the maximum size that can be processed is one piece (no splicing, preferred for high-precision grade 00/000) and multiple piece splicing (extra large size, mostly used for grade 0 ordinary reference tables/equipment bases).
1. Our factory can achieve 4000mm × 2000mm × 700mm in a single piece (without splicing, with high-precision platforms of grade 00 and 000), with a conventional platform thickness of 150-400mm; heavy-duty bases can achieve 600-800mm;.
2. Multi piece splicing platform (can be made larger, mainly level 0, suitable for large equipment bases) Our factory can achieve 8000mm × 4000mm × 600mm (splicing short board: the accuracy at the splicing joint is slightly poor, and there is a slight risk of misalignment between the boards under long-term temperature and humidity cycles. High precision measurement should avoid splicing as much as possible).
3. Selection reference suggestions.
✅ Level 000/Level 00 Metrology Inspection Platform: Priority given to integrated whole piece, recommended ≤ 3000 × 2000mm.
✅ Level 0 large-scale assembly and equipment base: splicing solutions can be selected to achieve a size of 6 meters or even larger.
✅ Thickness selection: The larger the length and width, the thicker the height (thickness) must be to prevent deflection and deformation of the tabletop, for example, 3000 × 2000, starting from a conventional thickness of 500mm

2. How many micrometers can the flatness reach? Can the accuracy be achieved at level 00, level 0, or level 000? What are the levels of 000/00/0?
Our factory achieves different levels of precision for different sizes. The small-sized integrated platform (≤ 1500 × 1000mm) can be used for all levels of 000/00/0, and can be ground and tested in a constant temperature and humidity workshop. Medium to large-sized integrated whole piece (1500 × 1000~3000 × 2000mm), capable of stable operation at level 00 and 0; Customization is possible at level 000, but the difficulty is high, requiring long-term constant temperature aging, ultra precision grinding, and shock-absorbing foundation;
3. Should we use Jinan green or other granite?
The commonly used stone materials in our factory are Jinan Qing, Indian, Zhangqiu, and Northeast materials. Jinan Qing is the benchmark substrate for precision granite platforms in China, and is the preferred choice for Class 000/00 high-precision; At the same time, other granite materials such as Indian black and Zhangqiu black can be selected according to the customer's budget and usage.
