3.1.12 Torch lift
Torch lift is driven by the lift motor through the screw guide rail slider, so that the torch for connecting up and down movements, so that the cutting nozzle and cut between the work piece to maintain the appropriate distance. With the above longitudinal and lateral motions, the torch can then be moved to any point on the X, Y coordinates. Cutting distance of the lifting is also achieved by cutting the thickness of the different requirements of the adjustment.

3.1.13 Plasma cutting system
Plasma power supply according to the size of the power supply installed in the beam or fixed ground position, plasma cutting torch mounted on the lift, automatic lift with a capacitor or height adjustment arc voltage automatic elevation system to ensure that the cutting height position and the steel plate constant, Control system panel automatically / hand control from the arc, arc, can be plasma cutting.

3.1.14 Plasma torch arc pressure increase
The cutting quality is best when the distance between the cutting tip and the work piece is 3 to 5 mm during plasma cutting, and should be controlled by the non-contact sensing device. During the whole cutting process, the non-contact height sensor. The distance between the work pieces remains constant, ensuring the cutting quality during plasma cutting.

3.2 Electrical control part
CNC drilling Cutting Machine's electrical control part, by the CNC, electrical, servo three subsystems, factory production CNC cutting machine control system are used in the main part of the original import, foreign brands. The system uses modular structure, wiring simple, reasonable, standardized, easy maintenance, large-scale use of integrated circuits, with small size, stable performance advantages; system also has fault history, fault alarm, self-diagnosis, effective protection of personnel and The system has a variety of language menu (including Chinese), can be very convenient man-machine dialogue, with a variety of input methods, flexible operation, but also with the PC communication to achieve automatic programming, the realization of computer operation, greatly Convenient for the user, save time, ensure the operation is stable and reliable.

3.2.1 CNC system
Spain FAGOR 8055 numerical control system
It has excellent intelligence and a wide range of uses, can do almost all of the automatic drilling and cutting processing, powerful, easy to use, easy to learn to use, drilling and cutting processing is more popular control system can be applied to CNC lathes, CNC grinding machines and other types of processing occasions.

3.2.2 Electrical systems
The use of modular design, wiring is simple and reasonable, standardized, coupled with a large number of well-known brands at home and abroad use electrical components, cables, accessories, to ensure that the electrical part of the reliability.

3.2.3 Servo system
Servo system selection of imported famous brands:
Japan's Matsushita and Spain FAGOR all-digital AC servo system:
Japan Matsushita and Spain FAGOR AC servo drive
Japan Matsushita and Spain FAGOR AC servo motor

1) AC servo motor is small size, the output torque, response quickly, using incremental pulse encoder as the position feedback and speed feedback components, easy installation, beautiful appearance.

Main and auxiliary rails to maintain a certain degree of parallelism, flatness, the main rail ends are equipped with anti-collision block, to prevent the derailment rack.

4.Processing applications
CNC drilling machine with a drilling function, the maximum thickness of the plasma cutting edge thickness can be achieved cutting. For example, a plasma power supply perforation cutting thickness of 25mm, edge cutting thickness of 50mm, only need to drill hole in the starting position of drilling a small hole, so that the thickness of the plasma cutting thickness can be achieved cutting edge 50mm, effective Users save on the cost of buying equipment. Cut the sample as follows:

NC drilling cutting machine as a result of CNC cutting machine gantry and rail structure, so the structure is not only diverse and simple configuration changes to achieve the enterprise of universal, modular manufacturing.
