Do you understand the hydraulic system of CNC lathes?

On the surface, the rotary table of the auxiliary device of the CNC lathe is similar to the indexing table of the general machine tool, but its structure also has its own characteristics. It is mainly composed of a transmission system, a clearance eliminating device and a worm gear clamping device. Mainly for circulation feed movement; Do the index.

Indexing table is different from CNC rotary table, its function is to achieve indexing movement, and the difference with rotary table is that indexing table can not achieve cyclic feed. The movement of the index table is limited to the specified Angle, such as :90 degrees, 60 degrees, 45 degrees. The indexing table is guaranteed for its own high precision requirements, so it must be used with the positioning machinery, so as to ensure the safety of the machine work.

There is no special requirement of power supply, usually allowed to fluctuate ±10%, but due to the specific situation of China's power supply, not only the power supply fluctuation amplitude (sometimes far more than 10%), poor quality,AC power supply is usually superimposed with some high-frequency clutter signals, with an oscilloscope can be clearly observed, sometimes there will be a larger instantaneous interference signal, Destroy the program or parameter of the CNC system, affecting the normal operation of the machine tool. The use of a dedicated power supply (separate from the low-voltage switchroom for the CNC machine) or increased stable pressure installation charm can reduce the impact on the quality of the power supply and reduce electrical interference.

Automatic tool changing device: Automatic tool changing device is a machining center that is different from other CNC machine tools. It has the function of automatically replacing the required tool according to the processing process requirements, which helps the CNC machine tool save auxiliary time and meet the requirements of completing multiple processes and working steps at one installation. Therefore, in the operation and use, it is necessary to pay attention to often check whether the mechanical structure operation of the components of the automatic tool changing device works normally and whether there are abnormal phenomena; Check whether the lubrication is good, and pay attention to the reliability and safety check when replacing the knife.

CNC lathe customization manufacturers talk about hydraulic system

(1) Regularly check, filter and replace the oil in the tank;

(2) Check the performance of the cooler and heater and control the oil temperature

(3) Regularly check and replace seals to prevent leakage of hydraulic system;
