XH717 vertical machining center
XH717 vertical machining center main performance characteristics
1, the base, slider, workbench, column, spindle box and other main foundation parts are made of high rigid cast iron structure, in the internal distribution of mesh structure reinforcement, to ensure the high rigidity and flexural damping performance of the foundation parts; The base parts are molded with resin sand and treated by aging process to ensure the stability of machine tool accuracy in long-term use and provide a guarantee for the stability of machine tool performance.
2. X, Y and Z direction guides are widened rectangular sliding guides, which have been quenched and precisely ground by intermediate frequency; The sliding guide surface is covered with PTFE material and precision scraping, with automatic forced lubrication, reduce the friction resistance of feed movement, reduce low speed crawling, improve the precision life of the machine tool;
3, Z to add counterweight block balance, to ensure smooth and stable spindle box movement; The joint surface between the bottom of the column and the base adopts the long-span "people" type structure, the column body chooses the very reasonable "people" support point, the stable triangle mechanics, so that the steadiness of the fuselage is improved to the best height of the column body.
4, X, Y, Z three direction feeding adopts large pitch high precision and high strength ball screw, high feeding speed; The servo motor uses the elastic coupling and the lead screw to connect directly, the feed servo motor directly transfers the power to the high-precision ball screw, to ensure the positioning accuracy of the machine tool;
5. The lead screw support adopts pre-stretching structure, which greatly reduces the influence of thermal deformation on precision in long time operation of the machine tool;
6, Adopt Taiwan famous brand high speed, high precision, high rigidity spindle unit, axial and radial bearing capacity is strong, speed up to 8000rpm;
7, the spindle can use high-performance temperature control system, the heat generated by the spindle away, so that the spindle unit temperature and room temperature balance, greatly reduce the impact of thermal deformation on spindle rotation accuracy, prolong the service life of the spindle;
8, X, Y, Z direction guide and lead screw are sealed protection, to ensure the clean lead screw and guide rail, to ensure the transmission and movement accuracy of machine tools;
9, the machine tool external protection adopts fully closed mechanism design; Safe and reliable;
10, the machine operating system adopts ergonomics principle design, operating box set independently, close to the operator, equipped with hand-held electronic handwheel operating box, convenient knife;
11, the use of advanced centralized automatic lubrication device, timing, quantitative automatic intermittent lubrication, stable and reliable work;
12, the machine supporting imported famous CNC control system, complete functions, easy to operate, stable accuracy, reliable;
Electrical system adopts transformer and control system separation design structure, reduce the heat generation, reduce the temperature change of electrical box, improve the service life of electrical parts and the reliability of system control;
