The main characteristic of economical CNC machine tools

CNC machine tool operation and monitoring was done in the numerical control unit, it is the brain of a CNC machine. Compared with the ordinary machine tool, CNC machine tool has the following features:

1.High machining precision, has the stable machining quality.

2.For multi-axis linkage, to processing complicated shape parts;

3.Machining parts change, generally only need to change the CNC program, production preparation time can be saved.

4.High precision of the machine tool itself, big rigidity, can choose favorable processing amount, high productivity (usually 3 ~ 5 times of the common machine tool).

4.Machine tool automation degree is high, can reduce labor intensity;

5.To operating personnel’s quality request is higher, the maintenance personnel of the higher technical requirements.

CNC machine generally consists of the following several parts:

1.Host, he is the theme of the nc machine tool, including machine body, columns, spindle and feed mechanism such as mechanical parts. He is used to complete a variety of mechanical parts machining

2.Numerical control device, is the core of the nc machine tool, including hardware (printed circuit board, CRT displays, the key box, paper tape reader, etc.), and the corresponding software is used to enter the digital parts of the program, and complete the input information storage, data transform, interpolation algorithm and implement various control functions.

3.Drive, he is the CNC machine tool of the actuator drive components, including spindle drive unit, feed unit, spindle motor and feed motor, etc. He in the numerical control device by electric or under the control of electro-hydraulic servo system to realize the spindle and the feed drive. When several feed linkage, can complete positioning, line, plane curve and space curve processing.

4.Assist device, index of machine tool some necessary auxiliary parts, to ensure the operation of the nc machine tools, such as cooling and chip removal, lubrication, lighting, monitor, etc. It consists of hydraulic and pneumatic device, chip removal device, change table, and CNC dividing head, nc rotary table also includes tools and monitoring detection device.

5.Programming and other accessories, can be used to in closed parts of programming, storage, etc.
