25 SERIES INTRODUCTION
25 SERIES 500
Product Features
● 45° overall inclined bed design, high rigidity, smoother chip removal;
● Finite element structure analysis, reasonable layout of casting ribs, good force effect;
● X/Y/Z/A axis lead screws are all pre-stretched structures, which can reduce the influence of temperature rise on the accuracy of the lead screw during processing, and add oil seals to protect the screw bearing at the installation on both sides of the lead screw, and silent ball screws;
● The tailstock adopts V-shaped guide rail, strong heavy-duty rigidity, upper and lower layered structure, and a micro-adjustment device between the upper and lower layers, which is convenient for the tailstock top swing center to be fine-tuned in the X-axis direction, and the standard live center structure tailstock;
● HENGDA independently designed integrated permanent magnet synchronous headstock box, low noise, high precision, long life, high finish, constant torque output, high C-axis positioning accuracy;
● Wide range of options: such as feeders, parts catcher, large hollow chucks, enlarged spindle through-holes, tool setting instruments,Programmable tailstock, The second spindle can be docked at high speed,automated truss robot;
● The machine tool adopts modular design, and selects different functional equipment according to different customer product requirements, which can quickly realize the automation device and meet the needs of customers;
