1. The product workpiece specifications are accurate, and the surface layer is not smooth.
Common faults: CNC blade tip knives are damaged and are not sharp; CNC lathes cause co -earthquakes and unstable placement; CNC beds have crawling conditions; processing process is not good.
Solution: After the CNC blade is damaged or damaged, it is not sharp after being damaged or damaged, then polish or select a faster CNC blade from the new knife; CNC lathes cause co -seismic or unstable storage, regulate the level, lay the foundation, fixed and stable; mechanical equipment and equipment; The reason for crawling is that the sliding rails of the plate are damaged strongly. The rolling beads are damaged or loosened. The CNC lathe should pay special attention to maintenance. After the commuting time, the steel wire should be cleaned up and immediately add lubricating fat to reduce the friction; the selection is suitable The frozen liquid processed by the product workpiece, under the circumstances that can be processed by other process process processing, use a higher machine tool spindle speed ratio as much as possible.
2. Product workpiece is smooth and small.
Common faults: The level of CNC beds is not adjusted well, one high and one low, causing unstable placement; when milling short shafts, the dedication of the raw materials is very hard, and the CNC knife is very deep to make the knife condition; the lathe knife rack frame; The mold thimble is different from the main axis of the machine tool.
Solution: Apply the level of the level of controlling the lathe, lay a solid roadbed, and fix the fixation of CNC lathes to improve its ductility; choose a scientific and reasonable processing process and reasonable drill cutting speed to prevent the tolerance of CNC blades; Adjust the lathe knife rack.
3. The phase differential light of the controller is normal, and the processed work
Common faults: The long -term high -speed operation of the CNC lathe stretch board causes damage to the roller screw and shaft sleeve; the repeated accuracy level of the knife head causes errors in long -term applications; the bracket can accurately return the starting point of the processing, but the processing of processing, but processing The specifications of product workpieces still change. Such conditions are generally caused by the main axis of the machine tool. The rapid rotation of the main axis of the machine tool has severely damaged the scroll bearing, causing the processing specifications to change. Thank you for your care of CNC machine tool automation technology. Mobile WeChat: CNCAUT.
Solution: Use the inner diameter percentage table to lean on the bottom of the knife head. At the same time, according to the system software, write a fixed non -dynamic circulating system program process, check the repeated accuracy level of the support board, adjust the gap between the screw of the beads, and disassemble the rolling shaft; use it with Inner diameter percentage table to check the repeated accuracy level of the knife head, adjust the mechanical equipment or disassemble and replace the knife head; if the inner diameter percentage table is used to test the processing of the processing product workpiece of the processing product, if it is possible, the main axis of the machine tool, disassemble and exchange Rolling bearing.
4. The size of the product workpiece is several millimeters apart from the specific specifications, or there is a large change in a certain radial direction
Common faults: The speed of rapid and accurate positioning is too fast to promote the not return to the motor; after long -term rubbing consumption, the bracket roller and rolling bearing of the mechanical equipment are tightened. Loose; the process of the program is incorrect, the head or tail is not reflected or the knife is not canceled;
Solution: The fast and accurate positioning rate is too fast, then the rate of GO is moderately regulated, and the drilling increase rate and time make the controller and motor in normal work at the operating frequency of the rated value; The rolling bearing of the rolling bearing of the roller and the roller screw crane must be adjusted again; after the knife head is changed, it is too loose to check whether the turning time of the knife head is reached. Is it very large, whether the installation is too pine, etc. If it is caused by the procedure process, you need to change the procedure process, improve in accordance with the provisions of the product workpiece engineering drawings, select scientific and reasonable processing process, and write properly in accordance with the command of the instruction manual in accordance with the instructions of the instruction manual. The procedure process; if it is found that the specification error is very large, check whether the main parameters of the system software are valid, especially whether the main parameters such as the transmission gear and the horizontal distance angle of the electronic device are destroyed. To accurately measure.
