| YK7232A CNC WORM WHEEL GEAR GRINDING MACHINE |
YK7232A is a kind of precision worm gear grinding machine with good
universality and efficiency used for grinding tooth flanks of
standard gears or dressed cylindrical involute gears, especially
for the precision grinding of the middle-sized-module and harden
gears adopted in aircraft, automobile, machine tool, motorcycle,
textile machinery, gear box and all kind of driving devices in
batch.
Features
The phase-locking servo drive system is used to replace the
original gear drive devices for the gear indexing drive chain and
differential drive chain, which improve the grinding accuracy and
reduce the waves on the ground tooth flanks. The variable radial
feed of wheel is realized by numeric feed-in system which improves
the machine efficiency greatly.
The movement of the workpiece slide is controlled by proportional
valve with grating scale feedback function, and different speed can
be set for every travel. The evenness of the grinding allowances on
two flanks of each tooth can be displayed, and the allowance can be
made even with a button.
Diamond roller is used for the wheel dressing.
This 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.
Manual and automatic grinding cycle selection is available. During
the automatic grinding cycle, workpiece can be clamped, unclamped
and shifted across the grinding wheel repeatedly so as to guarantee
the accuracy and uniform quality of workpiece in one batch.
The workpiece parameters and processing parameters are input via
the touch-type keyboard and displayed in Chinese on the CRT, and
all kinds of processing parameters can be stored in the computer.
