The following matters need to be noted when operating the valve drilling and tapping combination machine:
1. Before operation
Equipment inspection
Check whether all parts of the machine tool are intact, including the electrical system, hydraulic system, cooling system, transmission system, etc. Ensure that all parts are firmly connected and there is no looseness or damage.
Check whether the tool is installed correctly and whether the wear of the tool is within the allowable range. Replace the tool if necessary.
Check whether the fixture is firmly installed and the clamping force is appropriate. Ensure that the workpiece will not loosen or move during processing.
Check whether the lubrication system is normal and whether each lubrication point is fully lubricated.
Safety protection
Wear personal protective equipment, such as safety helmets, safety shoes, protective glasses, etc.
Ensure that the environment around the equipment is safe, without obstacles and dangerous items.
Check whether the safety protection devices of the equipment are complete and effective, such as protective doors, protective covers, etc.
Be familiar with the equipment
Carefully read the equipment's operating manual and safety regulations, and understand the equipment's performance, structure, operation methods and precautions.
Be familiar with the equipment's control panel and operation buttons, and master the equipment's start, stop, feed, speed adjustment and other operation methods.
2. During operation
Workpiece installation
Install the workpiece correctly on the fixture to ensure that the workpiece is accurately positioned and firmly clamped.
When installing the workpiece, be careful to avoid collision between the workpiece and the tool, fixture, etc.
Equipment startup
According to the startup sequence of the equipment, start the auxiliary systems such as the cooling system and lubrication system first, and then start the spindle and feed system.
When starting the equipment, pay attention to the operating status of the equipment. If there is any abnormality, stop the machine immediately for inspection.
Processing operation
Select appropriate tools and processing parameters according to the processing technology requirements. During the processing, pay close attention to the operating status and processing quality of the equipment, and adjust the processing parameters in time.
When drilling and tapping, pay attention to controlling the feed speed and cutting depth to avoid tool damage and workpiece scrapping.
During the processing, pay attention to cooling and lubrication to ensure that the tool and workpiece are fully cooled and lubricated.
Safe operation
During the operation of the equipment, the protective door and protective cover must not be opened. It is strictly forbidden to put your hands or other parts of the body into the equipment.
During the processing, pay attention to the operating status of the equipment. If there is any abnormality, stop the machine immediately for inspection. The equipment must not be operated with illness.
When replacing the tool, stop the machine first, and then replace it according to the operating procedures. After replacing the tool, the tool should be aligned and tested to ensure the processing accuracy.
3. After operation
Equipment shutdown
After the processing is completed, stop the spindle and feed system first, and then stop the cooling system, lubrication system and other auxiliary systems according to the shutdown sequence of the equipment.
After shutdown, clean the chips and oil stains on the equipment in time to keep the equipment clean.
Equipment maintenance
Regularly maintain the equipment, including cleaning, lubrication, tightening, adjustment and other work. Ensure the stable performance of the equipment and extend the service life of the equipment.
Check and replace the wearing parts of the equipment, such as tools, fixtures, bearings, seals, etc. Ensure the normal operation of the equipment.
Safety inspection
After the operation, the equipment should be inspected to ensure that the safety protection devices of the equipment are complete and effective.
Turn off the power switch of the equipment, lock the control cabinet and operation panel of the equipment to prevent others from misoperation.
