1.
Introduce
The horizontal boring and milling machine series HBM-130
of our company is suitable for such operation as drilling,
counter-boring, boring, reaming, spot-facing, tapping and milling etc.
Also the horizontal boring and milling machine type is equipped with
fixed facing head on which radial facing slide can be radically feed
consequently to enable the machine to undertake boring of
large-diameter hole, external cutting ,end face turning and recessing,
etc.
The machine is composed of bed, front column, headstock,
cross and longitudinal saddle, worktable, back column and balance
weight pulley etc. The vertical movement of headstock goes along the
column's guideway, the worktable can move transversely and
longitudinally on the bed, and the worktable can be
rotated.
The characteristics of HBM-130
2.1 The big
servo spindle 22KW motor supply continuously speed change and high
torque output of
headstock.
Four speed range can
be changed by the selector on the control panel.
The infinit
speed change in each range can be effected continuously and smoothly.
It?s very simple and
convenient for machine operation.
Compare with old headstock structure, 24 steps speed changing by
hydraulic, the failure rate will be reduced 80%.
2.2 The
vertical coordinate ( headstock lifting direction ) and cross
coordinate ( worktable transverse movement ) and longitudinal
coordinate ( worktable longitudinal movement--option ) are provided
with new type digital read out unit with memory function, which makes
the machine with complete function and high accuracy.
2.3 Main
parts of the machine such as bed, front column and guideways of
longitudinal saddle are all hardened and ground, which bring high
stiffness of the guideways and extend the using life of the
machine.
2.4 The horizontal guideway surface of the machine is
provided with all pull-board type dust-proof.
2.5
Electric-hydraulic interlocking device will be fixed between the
moving units and when a moving unit is working, the other moving units
will be clamped automatically (except spindle, radial facing
slide).
2.6 In the rapid traverse gearbox, safety clutches are
installed to prevent the machine from overload.
3.
Transmission systems of the machine
3.1 Headstock transmission
The rotation movement of boring spindle are driven by CTB servo
spindle motor directly. Insteady of old design, 24 steps spindle
speed, the spindle servo motor supply two range speed. Low spindle
speed with big torque output and high spindle speed with stable and
G41232403 continuously cutting forece.
3.2 Feed motion
The
feed motion of all moving units of this machine is feeding per spindle
revolution (e.g. traverse rate of spindle, headstock, table per
spindle revolution).The power of various moving units comes from shaft
driven by main driven motor. It can be transmitted through gears of
speed-change device to shaft (the feed safety mechanism). After that
the motion will be transmitted further through the forward and reverse
mechanism, to the feed shaft, then to the lead-screw or gear racks of
various moving units, enable the headstock, cross & longitudinal
saddles to obtain each 18 steps feed rates at low and high gear
respectively.
The feed motion of the radial slide on the facing
head comes from headstock, enable it to obtain various feed
rates.
3.3 Rapid transmission system
The rapid moving of the
headstock,cross & longitudinal saddles of the machine and the rapid
rotation of the rotary worktable are driven by AC motor mounted at the
right side of the bed. Power from the motor is transmitted from shafts
coupling and friction clutch to each moving units respectively, enable
the spindle, headstock and cross & longitudinal saddles to obtain the
rapid moving speed 2500mm/min, the rapid rotation of the worktable is
1r/min.
4. Hydraulic system of the machine
The
hydraulic system is located inside of longitudinal saddle of the
machine, which is used for the transverse of headstock, longitudinal &
cross movement, rotation of worktable, feed speed change and internal
lubrication of headstock
