The following is the operation guide of wheel hub repair lathe:
Beginner’s Guide
1. Preliminary Preparation
A. Check the lathe: Confirm that all parts of the lathe are intact, the lubrication system is normal, and there is no looseness, wear and other abnormal conditions. Check the electrical system to ensure that the power connection is stable, and the operating parts such as switches and buttons are sensitive and effective.
B. Clean the wheel hub: Use special wheel hub cleaning agent and tools to thoroughly remove dirt, grease, brake dust and other impurities on the surface of the wheel hub to ensure that the wheel hub is clean and tidy before repair8.
2. Install the wheel hub
A. Select the chuck and fixture: According to the size, shape and structure of the wheel hub, select the appropriate chuck and fixture. Common ones include three-jaw chucks, four-jaw chucks, etc., to ensure that the chuck and fixture can firmly fix the wheel hub.
B. Clamp the wheel hub: Place the wheel hub steadily on the chuck, and clamp the wheel hub evenly by adjusting the position of the chuck jaws. Pay attention to the installation position of the wheel hub during clamping to ensure that the center of the wheel hub coincides with the center of the lathe spindle.
3. Tool setting operation
A. Install the tool: According to the specific needs of the wheel hub repair, select the appropriate tool, such as diamond tool, alloy tool, etc., and install the tool correctly on the tool holder.
B. Manually operate the lathe: Use the manual operating handle or button of the lathe to bring the tool close to the wheel hub. Generally, move in the X-axis direction first, and then move in the Z-axis direction to approach the part of the wheel hub to be repaired.
C. Determine the tool setting point: Usually the edge of the wheel hub or a specific reference surface is selected as the tool setting point. Use a tool setting instrument or other tool setting tools to accurately measure the relative position between the tool and the tool setting point, and set the initial position of the tool in the lathe control system.
Advanced
1. Detect wheel curve
A. Install the probe: If the lathe is equipped with a high-precision detection probe, such as a ruby probe, install it correctly at the corresponding position of the lathe. For wheels of special depth, it may be necessary to install an extended probe 1.
B. Start the detection program: In the lathe control system, start the wheel curve detection program. The probe will move along the surface of the wheel hub, collect the contour data of the wheel hub, and transmit the data to the control system of the lathe.
C. Data processing and display: The lathe control system will analyze and process the collected data, and display the curve shape and related parameters of the wheel hub in graphical or digital form. The operator can understand the damage and deformation degree of the wheel hub based on these data.
2. Curve optimization and programming
A. Automatic optimization: Many wheel hub repair lathes are equipped with professional repair software with automatic curve optimization function. According to the detected wheel hub curve data, the software will automatically generate the best repair processing path and parameters to achieve accurate repair of the wheel hub1.
B. Manual programming: For some wheels with special shapes or complex damage, the operator may need to perform manual programming. According to the actual situation of the wheel hub and the repair requirements, enter the corresponding processing instructions and parameters in the lathe control system, including cutting speed, feed rate, cutting depth, etc.
C. Simulation processing: Before the formal cutting process, use the simulation processing function of the lathe to simulate the operation of the written program. Through simulation processing, you can check whether there are errors in the program, whether the processing path is reasonable, and whether the tool will collide with the wheel hub or other parts.
3. Cutting processing
A. Rough processing: According to the set program and parameters, start the lathe for rough processing. During rough processing, generally choose a lower cutting speed and a larger feed rate to quickly remove the damaged layer and excess material on the wheel hub surface.
B. Finishing: After the rough processing is completed, perform finishing operations. During finishing, increase the cutting speed, reduce the feed rate and cutting amount to obtain better surface finish and dimensional accuracy2.
C. Real-time monitoring: During the cutting process, the operator should closely observe the operating status of the lathe, including the cutting condition of the tool, the rotation of the wheel hub, the cutting sound, etc. At the same time, pay attention to the various parameters displayed by the lathe control system, such as cutting force, cutting temperature, etc., to ensure the normal processing process.
Mastery
1. Tool management and optimization
A. Tool wear monitoring: Regularly check the wear of the tool. The degree of tool wear can be judged by observing the cutting edge shape, cutting force changes, and surface quality of the tool. When the tool wears to a certain extent, replace the tool in time to ensure the repair quality and processing efficiency.
B. Tool parameter adjustment: According to the material characteristics, repair requirements and processing conditions of the wheel hub, flexibly adjust the tool parameters, such as the front angle, back angle, and blade inclination angle of the tool, to optimize the cutting performance of the tool and improve the processing quality and efficiency.
C. Application of new tools: Pay attention to the development of tool technology, and try to use new tool materials and tool structures, such as coated tools and super-hard tools, to improve the quality and efficiency of wheel hub repair and reduce processing costs.
2. Complex wheel hub repair technology
A. Special-shaped wheel hub repair: For various special-shaped wheels, such as multi-spoke, irregular shape, and special surface treatment wheels, it is necessary to have a deep understanding of their structural characteristics and repair requirements, use more complex programming techniques and processing technology, and combine manual operation and automatic control to achieve precise repair.
B. Repair of severe damage: For severe deformation, fracture, corrosion and other damage of the wheel hub, it is necessary to use a variety of repair methods, such as welding, heat correction, filling, etc., combined with the lathe repair process, to formulate a detailed repair plan, and strictly control the various parameters and quality requirements in the repair process.
3. Quality control and inspection
A. Processing accuracy inspection: During the repair process, regularly use measuring tools such as calipers, micrometers, dial indicators, etc. to inspect the size and shape of the wheel hub to ensure that the processing accuracy meets the requirements.
B. Surface quality inspection: Through visual inspection, roughness measuring instrument and other means, the surface quality of the wheel hub after repair is inspected, including surface roughness, whether there are defects such as knife marks, scratches, pores, etc.
