Maintenance and maintenance of CNC machine tool auxiliary devices

The maintenance and upkeep of auxiliary devices of CNC machine tools mainly include: the maintenance and upkeep of CNC indexing heads, automatic tool changers, and hydraulic and pneumatic systems.

1. Maintenance and maintenance of CNC dividing head

CNC indexing head is a common accessory for CNC milling machines and machining centers. Its function is to perform rotary indexing or continuous rotary feed motion according to the instructions of the CNC device, so that the CNC machine tool can complete the specified machining accuracy. Therefore, during operation and use Pay attention to the correct operation and use in strict accordance with the instructions and operating procedures of the CNC dividing head.

2. Maintenance and maintenance of automatic tool changer

The automatic tool changer is the characteristic structure that distinguishes the machining center from other CNC machine tools. It has the function of automatically changing the required cutting tools according to the processing technology requirements to help CNC machine tools save auxiliary time and meet the requirements of completing multiple processes and steps in one installation. Therefore, during operation and use, attention should be paid to frequently checking whether the mechanical structure of each component of the automatic tool changer is operating normally and whether there are any abnormalities; check whether the lubrication is good, etc., and pay attention to the reliability and safety of the tool change.

3. Maintenance and maintenance of hydraulic system

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

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

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

(4) Regularly check and clean or replace hydraulic parts and filters, and regularly check and clean oil tanks and pipelines;

(5) Strictly implement the daily inspection system to check whether the leakage, noise, vibration, pressure, temperature, etc. of the system are normal.

4. Maintenance and maintenance of air pressure system

(1) Select a suitable filter to remove impurities and moisture in the compressed air;

(2) Check the oil supply of the lubricator in the system to ensure that there is an appropriate amount of lubricating oil in the air to lubricate the pneumatic components to prevent air leakage and component malfunction caused by rust and wear;

(3) Maintain the sealing of the pneumatic system and check and replace seals regularly;

(4) Pay attention to regulating work pressure;

(5) Regularly check, clean or replace pneumatic components and filter elements.
