2.Technical Performance Specification

(1) Machinery parts

In order to cater to customers requirements of high speed and high accuracy,our company takes into account the machinery structures which may affect the performance of the machine when designing ,processing and manufacturing,including friction, backlash,rigidity,inertia and so on in a comprehensive way. And we also use the computer to analyze dynamic characteristics of machine.

1.Machine body adopts industrial aluminum , which possesses high intensity and rigidity.

2.Horizontal guide adopts high precision linear guide to ensure the horizontal guide precision.

3.It adopts high precision stepper motor with biaxial core guide vertically and horizontally. The gear is of high precision ,and the whole transmission is realized through the action of gear and gear rack.

4.The gear rack is made of special alloy steel which meet the standard of 7grades after high finishing,thermal treatment, and re-finishing. All these process ensure the transmission of high precision and long life.

Electric torch hanger:It is driven by DC reduction motor,the cutting torch makes linear lifting movement by means of crew rod and precision guide.

(2) The electrical control parts

Electrical control parts of the CNC cutting machine consists of CNC system,electrical control system and step-by-step motor system. The CNC cutting system adopts modular structure which is reasonable,formal and with easy maintenance. It widely adopts integrated circuit which has the advantage of small size, stable performance.The CNC cutting system can show the fault history, and have the function of fault alarm, self diagnosis, which can effectively protect the safety of personnel and equipment.Meanwhile it also has a variety of language menu (including Chinese)which is very convenient for the man-machine dialogue, it possesses a variety of input methods with convenient operation and can realize the automatic programming with PC communication function. All these are of great convenience to the users and saves a lot of time while guarantees a stable and reliable operation.
