Large CNC engraving milling machine is a new type of CNC machine tool developed gradually in recent years. It makes up for the single defect of traditional CNC machine tool overcomes the shortage of high processing cost of light small products. It plays a very important role in people's production processing, shoe making, sculpture so on.

It is the difference between milling machine traditional machine tool. It has unique advantages over others.

First of all, in terms of efficiency, the mechanical spindle can continuously fine tune the speed, can perfectly control the cutting speed in the whole processing process, so as to obtain high machining efficiency.

Secondly, in the noise generated, the noise value can reach G1. When the spindle rotates at high speed, the noise is very small. The general engraving milling machine in the use process, the noise is relatively large, causing fixed fault to the operator.

Third, the engraving milling machine adopts high-precision imported parts of imported bearings, precision assembly testing can easily meet the higher requirements of processing production. In addition, in terms of running speed, the mechanical spindle of large-scale CNC engraving milling machine adopts high-speed precision matching with imported bearing rigid elastic pre tightening structure, which can obtain higher speed make the cutting tool play a better cutting effect. With the formulation implementation of the new five-year plan, large-scale CNC milling machine will be more more widely recognized applied in the future development of China's manufacturing industry.

1. After the machining is powered on, check whether the switches, buttons keys are normal flexible, whether the CNC dragon milling machine has abnormal phenomena.

2. After the program is input, the processing code, address, numerical value, negative sign decimal point of CNC long I milling machine should be carefully checked.

3. Measure calculate the workpiece coordinate system correctly. The results were checked again the coordinates were compared. Coordinate value, positive negative sign decimal point shall be carefully checked.

4. Before the workpiece is loaded, run the program without any load to see whether the program can be carried out smoothly, whether the installation of tools fixtures is reasonable, whether there is "over travel".

5. When cutting, the fast rate switch must be set to a lower gear.

6. When cutting feeding, when the tool runs to the position of 30 ~ 50 mm of the workpiece, it is necessary to verify whether the residual values of Z-axis X-axis coordinate are consistent with the machining program

7. In the process of cutting machining, the tool position should be re measured the tool compensation value complement number should be modified after sharpening changing the tool.

8. After the order is modified, the revised part should be checked carefully.

9. The machine tool can only be started after confirming that the workpiece is clamped. It is strictly forbidden to measure touch the workpiece when the workpiece is rotating.

10. In case of any abnormal situation such as workpiece jumping, shaking, abnormal sound fixture loosening, the machine must be stopped for handling.

11. After the emergency stop, the machine tool "return to zero" operation should be carried out again before the program can be run again.
