Introduction to the installation of turning tools

1) The cutter head should not be extended too long, otherwise it is easy to produce vibration during cutting, which will affect the machining accuracy and surface roughness of the workpiece. Generally, the extension length of the cutter head is not more than twice the thickness of the cutter bar, and the cutting tool tip can be seen for turning.

2) The tool tip should be the same height as the centerline of the lathe spindle. If the turning tool is installed too high, the clearance angle will decrease, and the friction between the flank face and the workpiece will increase. If the tool is installed too low, the rake angle will decrease and the cutting will not be smooth, which will cause the tip of the tool to collapse. The height of the tip of the knife can be adjusted according to the height of the top of the tailstock.

3) The gasket on the bottom surface of the turning tool should be flat, and thick gaskets should be used as much as possible to reduce the number of gaskets. After adjusting the height of the tool tip, at least use two screws to tighten the turning tool alternately.

What are the electrical faults of fully automatic CNC machine tools?

1. Electrical failure of the machine tool. This kind of fault can be prompted by the alarm number of the self-diagnosis function of the machine tool, consult the ladder diagram or check the signal status of the I/O interface, according to the weekly report, data, troubleshooting flowchart and adjustment method provided by the automatic CNC lathe maintenance simulation sheet, and Check with experts. NCE for employees.

2. Amplify and detect the departmental failure of the tent sympathy service. This kind of failure can use the alarm number of the computer's self-diagnosis function, the computer's information status indicator, the servo amplifier drive board, and the failure alarm indicator. Refer to the transition value, voltage value and setting of the pivot test point introduced on the maintenance simulation sheet. Computer and servo amplifier board parameter setting, short-circuit pin setting and related potentiometer adjustment, function compatible board or spare board replacement. Use alternative methods for diagnosis and troubleshooting.

3. Computer department failure. This kind of failure is mainly diagnosed and eliminated through the alarm number of the computer's self-diagnosis function, the information status indicator on each board of the computer, the waveform and voltage value of each fulcrum, the adjustment of the relevant potentiometer, and the setting of the short-circuit pin. , Setting of machine parameters, special diagnostic components, and refer to maintenance manuals and electrical diagrams of computer control systems.
