CNC PLATE CUTTING AND DRILLING MACHINE
The CNC plate cutting and drilling machine machine is mainly used
for steel construction industry, agriculture machinery, engineering
machinery, ship building industries etc.
Machine body is composed of machine bed, Y axis feeding device,
marking unit, drilling unit, cutting system (plasma and flame
cutting), tool change system, machine bed roller etc. The machine
body is welded by high quality steel plate, closed type with high
rigidity. Marking unit, drilling unit, cutting system move and
position with the guiding of Y axis.
1.1 Marking unit:
Hydraulic disc marking with characteristic: many marking
characters, quick selection of character and clear marking
1.2 Drilling unit:
Adopts imported precise spindle (hollow), outer and inner cooling
(both are spray cooling). Equipped with spindle motor (servo
motor), the feeding spindle is composed of servo motor and precise
ballscrew. Hydraulic cylinder controls pressing of plate, guided by
Cutting system is composed of plasma and flame cutting. Customer
can choose the cutting way according to their requirement. For
plate with thickness 10 to 30mm(plasma HPR260), we suggest customer
to use plasma cutting, which has good cutting effect, high cutting
speed and good cutting quality. For plate with thickness larger
than 25mm,(MAXPRO200) we suggest customer to use flame cutting.
1.3.1 Plasma cutting system is composed of plasma source and height
adjusting system etc.
Adopts full set of America Hypertherm Maxpro 200 (or HPR260 XD for
option) plasma system and ArcGlide THC height adjusting system.
This plasma source has reliable capability, long life consumable
part and good cutting quality. The height adjusting system is the
newest product, which is reliable and easy to operate.
Take the following as example: oxygen air as plasma gas, air as
protection gas. This kind of gas combination can get max. cutting
speed, min. slag, min. surface nitridation and best welding
capability. Using 200A current (Max. cutting current), cutting
material is carbon steel.
ArcGlide THC height adjusting system can ensure good cutting
quality through arc pressure. The height adjusting system also has
cutting torch anti-collision function in order to avoid any
accident which will break the cutting torch.
1.3.2 Flame cutting system:
The propane is used as fuel, equipped with autoignition device and
the capacitance is adjusted higher, which is reliable and can
greatly improve the processing efficiency.
1.4 Tool change system:
Tool change system is composed of air cylinder, linear guideway,
crossbeam and 6 broach shells etc. The structure is very simple,
speed is high and strong reliability. Tool change capacity: 6
1.5 Machine bed roller:
It is mainly composed of roller and material pushing system. It
provides assurance to the plate feeding and drilling. There is
supporting device among the rollers which can strengthen the
1.6 Swarf cleaning device:
It is composed of lifting frame, steel wire brush roller and
hydraulic motor etc. It is mainly used to clean the swarf left on
the plate after drilling, so as to ensure the smooth progressing of
next processing step (cutting). The working process is: hydraulic
motor drives the steel wire brush roller rotates, lifting frame
goes down to touch the plate surface, plate moves under the action
of clamp, then the swarf can be cleaned. After cleaning swarf, the
lifting frame goes up, then machine starts cutting.
