Basic Information

Gear Grinding Machine This machine is a precision gear grinding machine with good universality and efficiency. It is used to grind tooth flanks of standard gears or dressing cylindrical involute gear. It is suitable for precision grinding of the middle-sized-module, harden gears used in aircraft, automobile, machine tool, tractor, motor-bicycle, textile machinery, gear box and all kinds of driving devices in batch process. FEATURES:The phase-locking servo drive systems which are used to replace the original gear drive devices for the gear indexing drive chain and differential drive chain improve the grinding accuracy and reduce the waves on the ground tooth flanks.Numeric in-feed system which is used to realize the variable wheel axial in-feed raises the working efficiency of the machine.The movement of the work-piece slide is controlled with a proportional valve, and a grating scale is used for its feedback. Different speed can be set for every travel.The evenness of the grinding allowances on the two flanks of each tooth can be displayed, and the allowances can be made even with a button if not even.Diamond roller for wheel dressingThe machine is equipped with lead crowning device for grinding gears with lead crowning, and gears with modified tooth profile can be ground after the wheel is dressed with special diamond roller.Selection of manual and automatic grinding cycles is available for use. During the automatic grinding cycle, a work-piece can be clamped, unclamped and shifted across the grinding wheel repeatedly so as to guarantee the accuracy and uniform quality of one batch of work-pieces.The work-piece parameters and grinding parameters are entered via touch-type keyboard, and displayed in Chinese or English on the CRT. Many kinds of grinding parameters can be stored in the computer.The CNC system has self-diagnostic function.SPECIFICATION:Outside diameter Φ20Φ320 mm No. of teeth: single-start 12256 Module: single-start 16 mm Max. face-width (spur gear) 170 mm Max. helix angle ±45° Distance between centers 180420 mm Max. travel of work slide stroke 180 mm Rapid speed of work slide 400 mm/min Feed rate of work-piece (step-less) Feed rate of work slide 0.43.4 mm/rev Distance from work sled center to grinding wheel axis 170420 mm Speed of grinding wheel: Grinding Profiling 11001650 rpm 38.4 rpm Size of grinding wheel Φ400×203×100(80) mm Total in-feed of grinding slide (radial) 0.8 mm Automatic in-feed of grinding slide per work slide stroke 0.010.10 mm Max. travel of grinding slide 250 mm Rapid feed-reversal of grinding slide 40 mm Max. travel of dresser in wheel spindle direction: Axial Radial 165 mm 85 mm Tangential shifting of column: Manually · total Automatically · rating Automatically · variable 90 mm 4 mm 02.5 mm Taper bore of work spindle and tailstock center No. 3 Total power of motors 20 KW Net weight 6000 Kg Gross weight 7000 Kg Overall dimension of host machine (L×W×H) 2170×1595×2100 mm
