When operating the valve drilling and tapping machine, you need to pay attention to the following matters:
1. Before operation
Check the equipment
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. If necessary, replace the tool.
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.
Be familiar with the equipment
Carefully read the operation manual and safety regulations of the equipment to understand the performance, structure, operation method and precautions of the equipment.
Be familiar with the control panel and operation buttons of the equipment, and master the operation methods of the equipment such as start, stop, feed, speed adjustment, etc.
Perform an empty running test of the equipment to check whether the equipment is running normally and whether there are abnormal sounds and vibrations in various parts.
Preparation
Select appropriate tools, fixtures and measuring tools according to the processing requirements. Ensure that the specifications, models and materials of the tools meet the processing requirements.
Clean and inspect the workpiece to remove oil, rust and impurities on the surface of the workpiece. Ensure that the size, shape and surface quality of the workpiece meet the processing requirements.
Adjust the working parameters of the equipment, such as speed, feed rate, cutting depth, etc. Select appropriate working parameters according to the material, hardness and processing requirements of the workpiece.
2. During operation
Safe operation
Wear personal protective equipment, such as safety helmets, safety shoes, protective glasses, etc.
Comply with the safety operating procedures of the equipment and strictly prohibit illegal operations. The working parameters and procedures of the equipment shall not be changed without authorization.
During the operation of the equipment, the protective door and protective cover shall not be opened. It is strictly forbidden to put hands or other parts of the body into the equipment.
Pay attention to the operating status of the equipment. If any abnormality is found, the machine should be stopped and checked immediately. The equipment shall not be operated with illness.
Processing operation
Correctly install the workpiece on the fixture to ensure that the workpiece is accurately positioned and firmly clamped.
Start the equipment and process according to the predetermined processing technology. During the processing, pay close attention to the operating status and processing quality of the equipment and adjust the working parameters in time.
Pay attention to the wear of the tool and replace the tool with severe wear in time. When replacing the tool, stop the machine first, and then replace it according to the operating procedures.
During the processing, pay attention to cooling and lubrication. Ensure that the cooling system and lubrication system work normally, and add coolant and lubricating oil in time.
Quality control
Strictly follow the processing technology requirements to ensure that the processing quality meets the requirements. During the processing, self-inspection and mutual inspection should be carried out to promptly discover and correct quality problems in the processing.
Inspect the processed workpiece and measure the size, shape and surface quality of the workpiece. Ensure that the various indicators of the workpiece meet the design requirements and technical standards.
3. After operation
Clean the equipment
After the processing is completed, turn off the power of the equipment and clean the chips and oil on the equipment. Clean the equipment thoroughly to keep the appearance of the equipment neat.
Clean the fixture and tool, disassemble the tool for cleaning and maintenance. Disassemble the fixture for inspection and maintenance to ensure that the performance of the fixture is good.
Maintenance
Maintain the equipment according to the equipment maintenance manual. Lubricate, tighten, adjust the equipment regularly to ensure stable performance of the equipment.
Check and replace the wearing parts of the equipment, such as tools, fixtures, bearings, seals, etc. Ensure the normal operation and service life of the equipment.
Check and maintain the electrical system of the equipment to ensure the safety and reliability of the electrical system. Clean and maintain electrical equipment regularly, check the connection of wires and cables, and promptly detect and eliminate electrical faults.
Record work
Record the operation of the equipment and the processing quality, including the start time, stop time, processing quantity, processing quality, etc. of the equipment.
Record the maintenance of the equipment, including the time, content, and replacement parts of the maintenance.
Record the failure of the equipment, including the time, phenomenon, cause, and treatment method of the failure. To facilitate future equipment management and maintenance.
