Mount the zero tool of the machine on the spindle

Correct installation and adjustment of the inductive synchronizer is of great importance to the machining accuracy and normal use of the machine tool, and needs special attention. Installation and adjustment methods and installation requirements of the inductive synchronizer In order to ensure the detection accuracy, it is required to install the inductive synchronizer: check and correct the fixed length so that the parallelism of the fixed length side busbar and the machine guide rail reference plane is the full length; The parallelism tolerance of the mounting plane to the reference plane of the machine tool guide is the full length; the deflection of the fixed-length mounting surface should be less than the parallelism of the parallelism between the slider-side busbar and the reference plane of the machine tool guide.

The fixed-length reference side is spaced apart from the reference side of the slider, the gap between the sliders is fixed, and the gap between the four corners of the slider is not more than 9. The adjustment method of the shaft zero is performed after the induction synchronization ruler is correctly installed, and the shaft is returned to the zero position; With a standard gauge, we use a rounder, press it against the positioning end of the rotary table, and then install the zero tool of the machine on the spindle to find the checker. When the round is used, the corresponding axis reading is the axis. The reading on the zero tool at the reset point is the zero error, which is entered as a coordinate variable into the machine parameters.

When installing the inductive synchronization scale, be careful not to make the zero error too large. Therefore, according to the above requirements and methods, we first adjust the parameters to the actual measurement of the sub-axis CNC machine tool high-precision inductive synchronizer adjustment method to take the average difference as the parameter will be re-measured sub-axis: bit recovery is completed. Precautions After the above adjustment is completed, clean and install the inductive synchronizer shield and the machine guide rail cover, and apply protective glue on the joint of the shield to prevent iron filings and impurities from penetrating between the fixed and sliding gauges.

We believe that this marking method is not very good, and it is explained as follows: For the strip, the standard flange standard of China, the pressure vessel flange standard "Classification and technical conditions of pressure vessel flange" and the chemical industry flange standard "steel system The unit specified in the marking formula in the pipe flange type and parameters is 758, and the value is based on the actual nominal pressure value.

However, the new national standard still stipulates the value based on the English unit, the value of which is based on the nominal pressure value. For a person who is accustomed to the unit of measurement, it is easy to mistake the value in the mark as the actual value. Starting from the principle of standard versatility and unity, the same flange standard, it is necessary to unify the marking method.

Secondly, it is debatable whether the new standard is still marked by the value of the English unit. The State Council of the People's Republic of China issued the "Measures on the Unified Measurement System" in the year to determine the system as the basic measurement system in China. Over the past few decades, China’s promotion system, reform of the city system, and restrictions on the British system have achieved remarkable results. In particular, the State Council issued the "Order on the Implementation of a Legal Measurement Unit in China" on the day of the month, clearly stipulates that all units of measurement in China will adopt the "Statutory Unit of the People's Republic of China", and after years of efforts to promote it, the system is the basic measure. The legal measurement unit of the system has been deeply rooted in the hearts of the people, and engineering and technical personnel have become accustomed to using the legal measurement unit that is based on the basic measurement system.
