Vertical machining plays a very important role in our mechanical processing. What are the key points of using vertical machining in our use?
1. Optimize the machining path for vertical machining
The process route of vertical machining directly affects utilization rate, machining accuracy, and economy. While ensuring accuracy, it can output power in advance, achieve process convergence, short distance, less empty travel, less auxiliary time, and reduce the occurrence of interval faults, ensuring azimuth accuracy.
2. The planning of forward vertical machining and the degree of universality of operators
The planner distinguishes elements based on the type of parts, controls the sequence of machining programs and steps, selects reasonable machining paths, cutting tools, and application sequences, determines cutting and process parameters, and formulates reasonable machining rules; Operators must undergo professional training and education in the field of technology, pass the examination before they can take up their posts. They must have further learning and quality knowledge, be good at summarizing experience, and be able to clean up short-term shortcomings.
3. Optimize vertical machining programming
When processing multiple workpieces of different shapes, multiple identical secondary actions need to be completed, and multiple processing can be done with just one rule, simplifying the rules for programming forward power; Use the idle function to verify the correctness of the tool path. After inputting the rules into vertical machining, load the tool or workpiece to start idling. At this time, the spindle does not rotate, and the worktable actively runs to check whether the visiting tool will touch the workpiece or fixture. When driving vertical machining, set a reference point, connect the work coordinate system and programming together, and set the tool length compensation correctly, otherwise it will collide and expand.
What should be noted for the application of high-speed machining?
During high-speed machining operation, if the worktable suddenly stops running and the stepper motor does not shake, this phenomenon is usually caused by mechanical failure, but it may also be caused by control system failure. At this time, the worktable can be returned to the origin and the machining program can be restarted. If the worktable stops running until it reaches a certain position, it should be caused by damage, deformation, or foreign object jamming in a certain part of the transmission system. First, turn off the power supply of the high-speed machining control system, and then manually rotate the screw. If there is particularly high resistance in a certain part, or even cannot rotate at all, it proves that there is a problem in that part. Check whether the gap between the nut and the screw or sliding plate insert is too tight, whether there are foreign objects in the ball guide groove of the ball screw, and whether the screw is stuck. bending deformation, Is the flexible gear inside the stepper motor reducer loose or blocked by foreign objects.
Environmental temperature and humidity requirements, high-speed machining generally requires a constant temperature environment to ensure the working accuracy of the machine tool. Generally, a constant temperature of about 20 degrees Celsius is required. Extensive practice has shown that collision accidents are prone to occur during high temperatures in summer, and humid environments can also reduce the operational reliability of high-speed machining. Therefore, dehumidification measures should be taken in the environment of high-speed vertical machining to avoid circuit short circuits, CNC system misoperation, and collision accidents. At the same time, economical CNC lathes are also required to be far away from forging equipment, electromagnetic interference, welding machines, etc WEDM、 Vibration sources such as electric discharge machine tools.
