CNC shaving machineIt is a finishing machine and cutting the high precision finishing machine. The tool is driven by the pin, the part is fixed to the main machine by a pliers and turns compared to the tool. During the processing process, the relative movement of the tool and the part causes the tooth of the tool to gradually treat the dental shape of the part. In order to reach the required precision and quality quality, the movement and pressure of the shaving machine must be controlled with precision.
CNC shaving machineThe operating method is as follows:
1. Prepare before the operation
Familiar with machine tools: Understanding the basic structure of the tool-machine, the functions of each component and the functions of the CNC system, such as spindle, the tool holder and other parts of the machine -Sut, and how to program and operate via the CNC system.
Safety inspection: wear work clothes, safety helmets, glasses, gloves and other protective equipment to ensure the safety of the operating environment, clean the debris around the machine tool and avoid accidents.
Inspection of the equipment: check if all parts of the tool-tool are normal, including if the tool is correctly installed and tight, the contact surfaces of the interior holes, the end surfaces of the tool, the Mandrins and washer must be clean; Each hydraulic gauge is normal; On the guidance rails and the screws, are there iron places and oil spots?
Lubrication inspection: refueling as a function of the equipment lubrication table, reaching “five fixed” (timed, fixed point, fixed quantity, fixed quality, fixed person) and check whether the lubrication system is not obtained, if The oil pump pressure is normal and if the oil circuit is clean and free from impurities.
2. Power operation
Start the lubrication system: start the lubrication oil pump first to completely lubricate all parts of the tool-tool.
Low speed pre-operation: for situations where the machine is closed for more than eight hours, then activated, the low-speed operation must be executed for five minutes first, confirm that the lubrication system is not obtained And the transmission of the transmission of each part is normal before starting the work.
Back to the point of reference: Depending on the requirements of the machine tool, select the appropriate return to the reference point and return manually or automatically each axes of coordinates to the reference point of the tool-tool to guarantee the correct establishment of the system coordinates of the machine tool.
3. Grampage of the part
Choose the appropriate tightening method: Choose the appropriate tightening method depending on the shape, size and room treatment requirements, such as the use of special lights, children, upper tips, etc.
Correct the position of the part: When you tighten the part, you must make sure that the position of the part is correct. treatment requirements.
Fixing the parts: The parts that are loaded and tight must be firmly tight to prevent the part from moving or relaxing during treatment, but at the same time, be sure to avoid damaging the part or the machine tool due to ‘an excessive tightening.
4. Selection and installation of tools
Selection of tools: Select an appropriate razor depending on the material, hardness, gear module, number of teeth, helical angle and other parameters. At the same time, factors such as the precision of the tool and the resistance to wear must be taken into account.
Installation of the tool: Install the selected razor on the tool holder. Use special tools to tighten the tool according to the couple specified to make sure that the tool will not detach or move during treatment.
5. Treatment parameters parameters
Determine the use of the cut: depending on the material of the part, the precision requirements of the equipment, the performance of the tool and other factors, the use of the cut must be reasonably selected, such as the speed of Cut, quantity of power and cutting depth. In general, a greater quantity of cut can be selected during approximate treatment to improve treatment efficiency and during the treatment of the finish, the quantity of cut should be reduced appropriately to guarantee the accuracy of the treatment .
Define the cycle parameters: Depending on the requirements of the gear treatment technology, define the corresponding cycle parameters, such as the coarse fine shaving teeth, the radial supply preselect, the light finish, the micro trip -Ratour, etc.
6. Writing and entry of the program
Analyze and treat drawings: Carefully study the gear treatment drawings, determine the form parameters of the gear tooth, dimensional precision, surface roughness and other requirements, as well as stages and methods treatment.
Writing the Program Code: Use CNC programming instructions to write the machining program of the shaving machine as a function of the process of the process and the cutting parameters. During programming, pay attention to the logic, accuracy and safety of the program to avoid problems such as incorrect instructions or collisions.
Input and verification of the program: Enter the written program in the machine tool control system via the keyboard, the USB interface, the network, etc. of the CNC system. Once the entry is completed, the program must be carefully checked to check the program syntax errors, logical errors, etc. to ensure the precision of the program. The verification can be carried out by simulated operation, empty operation, etc.
7.
Start treatment: After confirming that the program is correct, select the appropriate start method, such as starting the automatic cycle, starting a single segment, etc., press the Start cycle and machine button- tool begins to treat according to the Preset program. During the processing process, we must pay particular attention to the operating state of the tool machine, observe the cutting state of the tool, the rotation state of the part, etc.
Real -time monitoring: Use the CNC system monitoring function to monitor various parameters during the real -time treatment process, such as coordinate values, power speed, spit, etc., to quickly detect abnormal situations and face it. If you find problems such as severe wear of tools, excessive cutting force, abnormal vibrations of the room, etc., you should adjust the use of cutting or stop for inspection in time.
Dimension measurement: During the processing process, regularly use measurement tools to measure the dimensions of the part, such as vernier calipers, micrometers, hardware measurement instruments, etc., to check if the thickness of The speed tooth, dental steps, common normal length and others the parameters meet the requirements. Depending on the measurement results, adjust the tools for the tool or the processing technology in a timely time to ensure the precision of the treatment.
8. Treatment of complete operation
Treatment stop: When the part is processed, press the stop button to prevent the tool with tool from running. After waiting for the machine to finish Q to stop, turn off the engine of the spindle and other related auxiliary equipment.
Delete the part: Remove the treated part of the tooltip and make sure to avoid collisions and scratches on the surface of the room. Clean the chips and oil spots on the room and perform the necessary anti-urisal treatment.
Clean the tooltip: Clean the chips, oil and other debris on the tooltip to keep the machine-tool clean. Clean and maintain tools, accessories, etc. And put them off correctly.
Stop and keep: turn off the power in accordance with the operating procedures for the tool-machine and do a good job to maintain the equipment, such as the application of anti -ist oil, covering it with protective blanket, etc. Complete the equipment use files and maintenance files for subsequent management and maintenance.
