Electronic CNC Punching Machine , Metal Pipe Punching Machine
The CNC turret punching machine equip Single servo motor driven system, adopts large
torque direct driven servo motor and driving unit with high overload capacity to realize low
energy consumption, high transmission efficiency, reliable performance and convenient
1. Adjustable speed and stroke:
The punch stroke can be selected according to the thickness of the sheet automatically,
improving the work efficiency.
The punch speed is adjustable during each point of each single station,
the machine can realize the high speed swift during empty run and low speed during real
punch, in this way, the punch quality can be improved effectively, and there is really no noise
The system features with over-current protection and mechanical overload protection devices.
The punch force can be automatically adjusted according to the sheet thickness and ram
running speed to make the punching quality reach a high level.
2. The turret with bushing is process in pairs
The turret is processed by special device to ensure the coaxiality of the upper and lower
turret and expand the service life of tooling; the bushed turret simplifies the turret structure
to extend the service life; long tooling can be used to increase the guiding accuracy and
expand the tooling service life (for thick sheet).
3. Imported pneumatic, lubricating and electric components ensure the reliability of the
4. Large lead guideway and ballscrew from Japan or Germany ensures high feeding precise.
5. Hard brush and ball mixed worktable reduces the noise and vibration during running
and also protects the sheet surface.
6. O-type welded frame has been vibrated for twice, the stress has been deleted completely.
The frame is processed by Germany SHW dual-side pentahedron processing center at one
time, no need to make second time positioning.
7. Floating clamp with large clamping force ensures the stable feeding; integrated carriage
ensures good rigidity and convenient movement of clamp.
8. The system is featured with the function of automatic clamp protection to avoid the
damage of tooling and clamp, ensuring the continuous running of the program.
9. The auto-index adopts high accurate worm wheel and worm mechanism, ensuring high
precise indexing. The Max. tooling diameter can reach 88.9mm and the auto-index can be
expanded to 4 nos.
10. Integrated beam structure to make the carriage and beam into one part, increasing the
rigidity and brings the accurate positioning. The machine can run much more stably during
high speed feeding and it puts an end to the deflection of X and Y axes.
11. X axis: adopts servo motor to drive the high precise ballscrew and the carriage is
featured with high rigidity and lightweight design. Y axis: servo motor directly drives the
feeding rack which is connected with the machine guideway, split type beam is fixed with
feeding rack,and the acting force will be transmitted to machine frame & ground via feeding
rack and guideway in order to reduce the self vibration of the beam. This structure is featured
with the characteristics of good rigidity, light in weight, low gravity, and good dynamic response
in the entire feeding system, stable running and good precise.
12. Central lubrication system is adopted to send the lubrication grease to the relative
lubricating point directly, reducing the friction of each working pairs and increasing the
13. Anti-sheet-deformation switch and sheet-anti-stripping switch are adopted.
The machine is of wide closure-type frame, which is solid, receiving tempering treatment.
It has follwing features: Streamline body with side pin-positioning, sleeve structure and thick
turret, accurate positioning, good guiding, high accuracy adjustable worm and gear mechanism,
German H+L hydraulic station with high performance and low energy-consumption, special
apanese FANUC Oip CNC Control, long ballscrew and guideway with high speed and
universal pneumatic and electric parts, auto floating clamp and stainless worktable with
steel ball and
brush on it.
Adopts the hydraulic system of the first class, whose stroke and speed are changed digitally,
the max-punch hit can be reached 600hpm, and that at 25mm pace can be up to 350hpm.
The large lead ballscrew and linear guideway of high precision are equipped for driving.
The first-class CNC system with digital alternating servo motor ensures the precision.
The imported pneumatic, hydraulic and electric components ensure the perfect quality.
The inlay turret of high precision owns the long service life, and the customer can select the
numbers of stations between 24 and 32.
After the advanced process and heat treatment, the service life of the tooling has been
extended to a large extent.
Adopting worm-wheel and worm mechanism of high precision, the auto-index, whose max.
is 88.9, can be extended.
The integral structure of beam and carriage enhances the rigidity and precision; It also ensures
the smoothness of feeding at high speed and eliminates the dynamic deflection of X, Y Axes.
