YZZX-2520 CNC double-sided milling and boring special machine by
two sides of the symmetrical layout of the bed, cross sliding
table, moving back and forth column,Vertical up and down moving
power head, circular indexing table in the middle, and automatic
chip removal and cooling device, pneumatic system,Electrical
system, tool library, etc.This equipment is mainly used for the
efficient processing of drilling, boring and milling of
double-sided holes of structural parts, and can realize the
functions of drilling through holes, blind holes, boring, milling,
tapping and so on the workpiece. The two spindles can
bedouble-sided machining at the same time, or they can work
independently, and themachine tool processing process is digitally
controlled, which is very convenient to operate. It can realize
automation, high precision, multi-variety, mass production.
(Device diagram)Customer storiesSecond, the characteristics of the
equipmentThis equipment is mainly composed of bed on both sides,
rotarytable, moving column, CNC horizontalpower head, automatic
chip conveyor and cooling device, pneumatic system, electrical
system, tool magazine, etc. The bed, column, spindle box and other
large parts aremade ofhigh-strength cast iron materials cast by
German resin sand production line, andare treated with artificial
aging heat treatment and annealing to eliminate internal stress.
Using finite element analysis, the static and dynamic performance
of the machine tool is effectively predicted and optimized, so that
the performance of the machine tool is effectively guaranteed, and
it has a high performance-price ratio. 1. Bed on both sides:The bed
base is made ofhigh-strength cast iron HT250 material cast by
German resin sand production line, whichhas high mechanical
stability and thermal stability. It adopts thin-walled multi-rib
structure and compact structure, which makes the machine tool have
high rigidity. After artificial aging heat treatment, annealing
stress removal treatment, eliminate internal stress. Good dynamic
and static rigidity. The bed is distributed on the left and right
sides of the workbench, and the longitudinal (X-axis) of the mobile
columnmoves against the bed slideseat at the level of the bed to
inlet the high-bearing capacity linear rollingguide pair and
precision ball screw pair, The drive is driven by a servo motor.
The double-sided synchronous drive guarantees the parallel movement
of the moving column, guaranteeing the perpendicularity of the Y
axis tothe X axis at any position. Adjustable bolts are distributed
on the underside of the bed, which can easily adjust the level of
the bed worktop.
Heavy-duty linear guide Precision ball
screw2. Move the columnThe mobile column adopts high-strength cast
iron HT250 material castby German resinsand production line,
whichhas high mechanical stability and thermal stability. It adopts
thin-walled multi-ribbed structure and compact structure, so that
the machine tool has high rigidity and is treated by annealing and
stress relief. The left and right moving columns are symmetrically
installed on the cross slide, and the imported high bearing
capacity linear rollingguide pair and precision ball screw pair are
horizontally arranged on the bed cross slide, and the drive is
driven by servo motor, so that the front and rear of the mobile
columnare fed motion (Z axis).On the front side of the column,
twolinear rolling guide pairs with ultra-high bearing capacity are
installed vertically. And the precision ball screw pair and AC
servo motor are installed above, so that the spindlepower box moves
upand down along the column (Y axis). The horizontal power head is
mounted in the middle of the front of the column. 3.

table is driven by the servo motor and ball screw to move back and
forth, and realize the power head fast forward, work forward, fast
rewind, stop and other actions. The cross CNC slide table isdriven
left and right by the servo motor on the bedto realize the column
fast forward, work advance, stop and other actions. 4. Boring
