Machine a "Fan Law" grinding process, combined with numerical control technology so that the whole grinding process by the CNC control system, by automatically grinding, good stability, operation and easy maintenance. CNC machine tools equipped with Nanjing, the earth system and drive control two stepper motor, CNC machine capabilities. MDI with a 6-inch LCD and integrated control panel and electronic hand wheel and RS232 interfaces. Horizontal grinding machine and table feed X-axis longitudinal movement by the stepper motor-driven Z-axis, through the precision ball screw coupling Direct seamless movement, using high-precision screw screw supporting bearing special bearing, the system rigidity good, high positioning accuracy.Machine tool spindle grinding head with sleeve type bearing spindle unit, matching precision pair group bearing support, and the use of oil lubrication and shaft-hole cooling system to ensure that high spindle rigidity, high precision, long life. The design of grinding machine spindle center adjustment agencies, to meet the grinding time "3" in high demand. Machine head and tail holder are used "dead" top structure, grinding spindle and head frame are used inverter motor drives, controlled by a frequency converter to achieve stepless speed regulation, to adapt to different workpiece grinding needs. Tailstock top with spring clamp, cylinder drive back; cooling system can be realized within the grinding axis outside the cooling and cooling functions, has a flushing effect of the workpiece and sand; reliable rail lubrication system and style, appearance, reliable and full protective closed shell.itemLTQM320center hightMM180processing dia rangeMMΦ80 Φ3202 8”maximum workpices weightKG150grinding head spindle speedRPM2000 5000Frequencygrinding head motor powerKW7.5Inverter Motorhead frame speedRPM10 80Frequencytop of the head fram and tailstockmohs4#Made by Carbidex,z Minimum feed resolutionMM0.001accracySteradianMM0.01Surface RoughnessRa<=0.4μm Use of numerical control systems and control of two AC servo drive motor, servo movement.

Machine with moving table structure, horizontal grinding table feed X-axis and Z-axis longitudinal movement by AC servo motor driven by precision ball screw coupling Direct seamless movement, screw ring bearing a high-precision screw special bearing, the system rigidity is good, high positioning accuracy. Cylindrical grinding machine tool spindle using Hydro-hybrid bearing units, and equipped with cooling function with the independent oil lubricant containers, to ensure spindle rigidity, high precision, long life. The design of grinding machine spindle center adjustment agencies, to meet the grinding time "3" in high demand. Machine head frame for the "live" spindle, tailstock a "live" top, machine tool spindle grinding head and the head frame are used inverter driven by the inverter control for stepless speed regulation, to adapt to different workpiece grinding needs. Machine tailstock mechanical locking sliding sleeve structure, hydraulic cylinder drive sleeve advance and retreat, to realize the workpiece clamping position. Cooling system can be realized within the grinding axis outside the cooling and cooling functions, has a flushing effect of the workpiece and sand; equipped with a reliable rail lubrication system and style, appearance, protective and reliable closed-shell. This machine is specially developed for the valve industry for grinding, "Chase Drive" sphere of CNC Spherical Grinder is mainly applied to symmetrical ball valve ball valve industry, high-volume grinding can also be used in other parts of the mill with a spherical cut processing. Use of numerical control machine tool control system and drive two AC servo motor, servo movement. Numerical control system with LCD display and the MDI-in-one control panel and electronic hand wheel and RS232 interfaces.
