High Stiffness Good Flexural Resistance CNC Gantry Machining Center

Liande CNC machine tool is one of the gray hair for lathe business and establish cooperation relationship with NSK, HIWIN, FANUC and other famous brand, at present we have developed 4 products series: CNC lathe machine, vertical machining center, gantry machining center, and wheel lathe for example CE, ISO9001 etc, in addition, we have a number of invention patent.

CNC gantry machining center has a structure of movable workstation and fixed beam gantry. The bed, table, column, beam and other basic parts are made of resin sand molding. CNC gantry machining center adopts High-quality high-strength cast iron HT300 by aging treatment with reasonable structure design, high stiffness, good flexural resistance and excellent stability and accuracy.

Features of CNC gantry machining center:
1. Base, table, column , beam, slide , headstock base and other major parts are made of cast iron HT300 , box-type structure, compact and reasonably symmetrical rib structure ensures high flexural rigidity and damping properties of the base parts;
2. Guide rail(X/Y direction) is Taiwan HIWIN linear motion guide with high loading capacity, high speed, high rigidity, low friction , low noise, low temperature rise and other changes characteristic;
3. Left and right side of headstock have a balance oil cylinder, automatic synchronization balancing by gas-liquid conversion device, no external power source.
4. X, Y, Z direction feed adopts outer cannula circulation double nut preloading P3 grade large lead ball screw with high rigidity, feeding speed is high;
5. spindle is connected by synchronous belt with high precision, low noise, maximum speed up to 8000rpm.
6. X, Y direction guide rails , screw protection devices are used to ensure screw and guide rail cleaning and the machine 's transmission and motion accuracy and useful life;
