C (X) 5225-125 series of ordinary (digital) double column vertical lathe

  ● Introduction to machine tools The series of machine tools for high-speed steel, carbide cutting tools and ceramic tools for ferrous metals, non-ferrous metals and some non-metallic parts of the rough, finishing. Worktable constant current hydrostatic system for synchronous motor oil separator. So that the hydraulic system work more stable and reliable. The electrical control for the PLc program controller controls the reduction of the control element. Reduce the failure rate. So that the machine moves more accurate and reliable.

  ● Machine basic parts  By the base, the table. Around the column, beams, connecting beams, gantry and other components, material for the HT250-300 quality alloy wear-resistant cast iron. The vibration aging of a hot furnace aging a vibration aging a roughing a vibration aging half of a finishing furnace a time of vibration aging finishing a work to eliminate the workpiece stress to ensure long-term operation accuracy of the machine.

● Spindle bearings  The use of high-precision double-row short cylindrical roller bearings, bed rail for the super-audio quenching processing, table and bed rail for the constant current hydrostatic guide, constant temperature cooling, to ensure that the machine has a high rotation accuracy and sufficient rigidity, Thermal stability.  

● Column  Using the gantry frame closed structure, through the finite element analysis and calculation, the structure size and force state to achieve the best.

● Vertical turret  Horizontal rails for sliding or static pressure unloading rails, vertical movement using sliding rails.

● X, Z and U, W axis feed system ≤ 4m for the AC motor drive trapezoidal screw separation drive mechanism,> 4m for the AC servo motor drive ball screw separation drive mechanism. According to the user need to select a single knife or double knife.

● Machine main drive Driven by the DC motor, the two-speed mechanical transmission mechanism, to achieve the speed range of the table.
