CNC High-Speed Gantry Moving Drilling Machine for Plates Model
TPM6040-2This machine is gantry moving CNC high speed drilling
machine, mainly uses for drilling and grooving work-pieces like
tube sheets, flanges, can adopt both internal cooling carbide
drills as well as external cooling twist drills. The two spindles
can work simultaneously or independently, CNC control, easy
operate, can realize automation, high precision, multi-scale,
mid-small amount production. Characteristics:This machine is
composited by machine bed & longitudinal slip plate, worktable,
gantry& transverse slipway, vertical ram type drill box, chip
conveyor, hydraulic system, pneumatic system, central lubrication
system, electric system. a. This machine is gantry moving,
reduces the machine length, saves occupying area. Machine bed and
gantry adopts steel plate welding structure, have done the manual
aging treatment, the precision is stable. Worktable, longitudinal
slip plate, transverse slipway and ram etc are iron casting parts.
There are T slots distributed on the worktable surface, for
clamping tube sheets and fixture.b. Movable gantry is
installed the left and right longitudinal slide carriages, which is
right-angle bending plate welding steel structure. A set of
transfer mechanism consisting of AV servo motor and high precision
rack assembly on the left and right sides respectively. The gear
assembly are connected with longitudinal slide carriages. When the
AC servo motor rotates, it drives the gear to move along the rack(X
axis), the slide carriage moves along the guide at the same
time.c. The movement of drilling box (Y axis) is guided
by two staged high precision linear ball screws equipped in front
of gantry beam, and driven by servo motor and large pitch ball
screws, the servo motor is transmitted by timing belt with rotation
of large pitch ball screw. Leading screw is pre-tightened by double
nuts, removed the gap. Y axis equips with Heidenhain Grating Scale,
formed fully closed loop control, with high transmission
precision.d. The vertical movement of Ram type drilling box (Z
axis) is guided by linear guide which locates at both sides of ram,
driven by servo motor and ball screw.Dydraulic balancing, every
drilling box can work independently. Z Axis equips with balance
cylinder, if the Z axis motor belt broken, it will drop very slowly
to stop until touches the buffering cusion which locates between
bearing base and screw nuts base, to avoid Z axis slide falls down
accidently.e. The drilling box is rigid high precise spindle,
adopts BT50 internal cooling spindle from Taiwan, with blowing
device. Also equips with Taiwan hydraulic tool cylinder, using
hydraulic -disc spring to do automatic tool de-clamping, tool
pulling, with tool status monitoring device to check the tool
clamping and effective safety co-locking protection device. Easy to
change tools. The spindle is driven by spindle servo and timing
belt, spindle speed is 30~3000r/min, large rotation speed range.f.
The hydraulic system is for auto tool device and weight balance of
ram type drilling box, unified oil supply; all the hydraulic units
are from imported brands or joint venture companies, for easy
maintenance and solving oil leaking, all the design adopts
accumulative valves. NameDescriptionValueMax. work-piece
