Talk about the problems that should be paid attention to in turning multi-thread threads

1. Line dividing method and correct line dividing. If the line splitting method is not properly selected, the line splitting operation is not correct, and the line splitting error occurs, the pitch of the multi-line thread being turned will be unequal, which will seriously affect the screwing accuracy of the internal and external threads and reduce the service life. 2. Taiwei machine tool reminds that the adjustment of lathe exchange gear should be determined according to the lead, and the position of lathe handle should be adjusted correctly. 3. The lead of the multi-thread is large, and special attention should be paid to the influence of the lead on the rear angle of the two cutting edges of the tool. Qingdao Taiwei machine tool suggests that its spiral lift angle should be calculated according to the lead, and attention should be paid to it in the sharpening market. 4. When finishing turning multi-thread threads, finishing turning should be done together after all spiral grooves are roughly turned, otherwise it is difficult to ensure the consistency of thread profile.

The role of instrumentation

The main function of instrumentation is: a technical process for measuring certain characteristics of substances and measuring and controlling them through the inherent law characteristics between these characteristics: in short, it is to convert the physical quantities in real life into a certain proportion of values through the measurement of instrumentation, and then to achieve the purpose of controlling the physical quantities in real life by means of proportional adjustment of the values.

Introduction to the use of common instruments

Multimeter is also called multimeter. It is a commonly used test instrument in power supply maintenance. Generally, multimeter can test voltage, current, resistance, wire on and off, diode voltage drop, triode discharge multiple, signal frequency, etc. It can not only test the voltage and current of alternating current, but also test the voltage and current of direct current. Multimeter usually uses "-" or "DC" to indicate DC file, use "~" or "AC" to indicate that it is an AC file. Pay attention to distinguish it before testing. Multimeter according to its display method is divided into different pointer and digital two types. Different types of multimeters have their own measuring ranges. Be careful not to exceed their measuring ranges when measuring, otherwise the multimeter may be damaged. Some multimeters have self-protection function. If they exceed their measuring ranges, they will give some kind of sound alarm. There are many types of multimeters, and their functions and usage methods are similar. The following is a model of multimeter to introduce the use of multimeters.
