CNC crankshaft special grinder
Machine Features:
★The machine tool adopts five-axis numerical control system, built-in PLC, and 10.4-inch color liquid crystal display. The operator can set the grinding parameters in the man-machine conversation mode through the display screen, edit the grinding process cycle, and realize the automatic grinding of the machine tool.
★Using a double-head frame to drive two sets of special eccentric V-shaped fixtures through two AC servo motors (C1, C2) to achieve synchronous rotation and machining of eccentric outer circles. Rigid positioning is adopted for the rotation of the headstock when loading and unloading workpieces.
★The workpiece corner is automatically positioned by the workpiece grinding outer circle; hydraulic automatic clamping.
★Use the rear diamond roller to dress the grinding wheel. The grinding wheel frame feed X1 axis and the diamond roller dressing feed X2 axis are respectively completed by the AC servo motor driving the ball screw, which makes the grinding wheel dressing and compensation more reliable.
★The machine tool is equipped with an outer circle active measuring instrument and an end face positioning device to realize axial positioning and closed-loop control of outer diameter grinding;
★The grinding wheel spindle adopts the German technology integral dynamic and static pressure bearing structure, which has high rotation precision and high rigidity; the independent static pressure oil tank uses No. 2 spindle oil and is equipped with a pressure gauge display.
★The headstock spindle of the machine tool adopts the precision rolling bearing structure and selects P4 grade bearings; adopts the AC servo spindle motor to realize the synchronous stepless speed change of the two axes, and has the function of accurate stop
★The machine tool adopts an integral casting high rigidity bed and a full protective cover (the upper part is open), and the glass window of the front door is protected by iron mesh and protective door lock. The four boxes of the machine tool (hydraulic oil tank, dynamic and static pressure oil tank, water tank, electrical box) are independent, which is convenient for operation and maintenance.
