Now the CNC machining process is still more popular in the processing industry, and everyone knows, after the CNC machining process is completed, what are the specific items that need to be checked?

Inspection of the feed axis

1. Manually operate each feed axis for low, medium and high speed feed and rapid movement, check whether the movement ratio is correct, whether it is smooth and smooth during movement, and whether there is noise

2. Manual data input mode (MDI) operation, through the GOO and GOl command functions, check whether the rapid movement and feed speed are normal.

Inspection of tool changer

The inspection of the tool changer is to perform the tool change step by step in manual mode, and CNC machining to check whether the actions such as grasping, loading, and pulling are accurate and appropriate. In the adjustment, a proofreading inspection method is used for testing. When there is an error, the stroke of the manipulator can be adjusted, the support of the manipulator can be moved, or the position of the tool magazine can be changed.

Mechanical zero inspection

Reliability inspection of the hardware and software limits of the vertical CNC machining center. The soft limit is generally determined by the system parameters, and the reliability of the soft limit can be completed by checking the system parameters; the hard limit is determined by the travel switch set at the limit position of each feed axis, and the reliability of the hard limit is determined by the reliability of the travel switch Decide. The reliability and accuracy of returning to the mechanical zero point are checked by returning to the origin method to check the zero returning performance of each feed axis.

The machining center for CNC precision machining is a relatively high-priced machine tool processing equipment. When buying it, you should try to be careful to avoid spending money to buy products of poor quality. Now in the large market environment, domestic machine tool manufacturers are highly competitive, and the price war is in full swing. This situation is not good for the healthy development of the machine tool industry, but it is beneficial to consumers. Manufacturers take the initiative Rangli, this is a great thing.

There are some pitfalls in the purchase of machining centers that I have to talk about. The so-called “you get what you pay for”, the configuration of the processing center and the price are directly proportional. Manufacturers that use low prices to seize the market will continue to reduce manufacturing costs in order to survive.
