The reason why many customers and friends purchase machining centers is precise because of the high precision and high efficiency of this equipment. In fact, in our machining industry, the long-term maintenance of good performance of any equipment is inseparable from standardized operating procedures. The same is true for CNC machining centers. CNC machining center is a highly confidential mechanical equipment integrating oil, gas, electricity, and integrated circuits. Orderly and standardized processing steps are more important.

Ready to start

The CNC machining center must return to the reference zero position after each startup or emergency reset. To allow the CNC machining center to have a reference position for future operations.

Clamp the workpiece

The surface of the workpiece should be cleaned before processing, especially before clamping. There can be no oil, iron filings, and dust. Use a file to remove burrs from the surface of the workpiece. The high-speed rail used for clamping must be ground by a grinder to make it smooth and flat. The CNC machining center workbench should be clean and free from iron filings, dust and oil.

Artifact software programming

The programmer should write the machining program for the workpiece that is being machined. Thereby, the tool path is generated, and the tool path is checked for interference through simulation. After the interference check, post-processing is performed to generate a safe and stable NC code, which is transmitted to the workshop.

Tool preparation

The tool is the executor of the operation of the CNC machining center. According to the material of the part to be processed, replace the corresponding tool.

Setting of machining parameters

Spindle speed: N=1000×V/(3.14×D) Among them, V=cutting speed D=tool diameter

Feed rate: F=N×M×Fn F=feed rate M=number of tool edges Fn=cutting amount of tool

Setting of cutting amount per edge: Fn=Z×Fz Z=number of cutting edges of the tool Fz=cutting amount of each cutting edge of the tool

Machining

First, check whether the tool for each part of the program is suitable for machining the workpiece. At the beginning of processing, the feed rate should be adjusted to the minimum. You should put your hand on the stop button and stop immediately if there is a problem, pay attention to the direction of the tool movement to ensure safe feeding, and then slowly increase the feed speed to an appropriate level, and at the same time, apply coolant or cold air to the tool and workpiece.

When starting rough machining, it should not be too far away from the control panel. If there is an abnormal phenomenon, it should be stopped and checked in time. In the process of processing, the processing parameters are continuously optimized to achieve the best processing effect.

Conclusion

As the saying goes, work slowly and work hard. As long as the CNC machining center operates properly, it can achieve slow work and clever work. If you still have questions about the operation of your CNC machining center, you are welcome to contact us, and we will serve you wholeheartedly.
