General Layout
This machine is composed of column, main gearbox, worktable, elevating
mechanism of crossbeam, vertical tool head, electrical system and
hydraulic system. Main gearbox is consolidated inside column, worktable
is consolidated in front of column and crossbeam can make up & down
movement on the guide way of column. On crossbeam a vertical tool head
is set, which can make horizontal & vertical feed or rapid movement.
Worktable is driven by AC motor. This machine is equipped with pendant
station on which all operation can be done concentrated.
Main Transmission Mechanism
The main transmission is driven by AC motor via hydraulic cylinder to
drive shifting fork for putting into gear and speed change so as to
enable worktable to obtain 5-160r/min speed with 16 steps speed
regulation and its operation is concentrated on the pendant station.
Feed Mechanism
The horizontal & vertical feed of vertical tool head is driven by AC
motor and the horizontal & vertical feed or rapid movements of
vertical tool head can be obtained by means of cutting feed box
Worktable
The hydro-dynamic guide way is adopted for worktable and on its main
spindle mounted with two sets 3182100 type double row shot cylindrical
roller bearings with its tapered inner ring via which the radial
clearance can be adjusted. Two bearings are all lubricated through
oilflow to ensure the axial and radial accuracy of worktable. Four hand
operated jaws are set on worktable surface.
Column
The column is connected with the base of worktable and made from high
strength & low stress cast iron. On the column the elevating
mechanism for crossbeam is set, which is driven by AC motor to realize
the up & down movement of crossbeam on guide way of the column.
Crossbeam
The crossbeam can make up & down movement on the guide way of column
and its elevation is done by single screw. On the crossbeam, safety
floating nut device is set for ensure the precise and safety of
crossbeam while elevating. The crossbeam is clamped tightly on the
column by hydraulic cylinder via lever multiplying and pushing wedge or
loosened, this clamping device is simple for easy maintenance and
operation.
Vertical Rail Head
The vertical tool head is of three-layer structure and composed with
slide base of crossbeam, rotary slide base and ram , both of them are
made from high strength & low stress cast iron and the ram is made
from nodular cast iron.
Hydraulic System
The hydraulic system is composed of hydro-dynamic guide way control
system of worktable, speed change of main transmission system, clamping
& loosening system of crossbeam and lubrication system of main
transmission. The main hydraulic parts are all from the famous
manufacturers inside China or in the world in order to guarantee these
parts quality performance. Lubrication method is of auto circulated
lubrication and oil hand pump lubrication.
