Computer sewing machine crashes after needle return 2) with the hardware relationship, less memory, CPU and other hardware temperature high-definition gray, hard disk problems with software to repair the software surface to uninstall the pre-load Win cleaning assistant to kill the Trojan original system or reinstall the full load to operate the computer card more reasons 1.The display card has poor contact with the display signal line 2.Monitor's own fault 3.The color is not normal when running in some software,Generally common in old-fashioned machines,There is an option to check the color in the BIOS,Turn it on 4.Video card damage;5.The monitor is magnetized,This kind of phenomenon is generally caused by being too close to objects with magnetic properties,Magnetic, after the transformation may also cause the display screen to appear the phenomenon of deviation.Although I know that you really want to get a positive answer, I suggest that you better replace a video card and suggest that you install

What is the speed of the spindle speed of the CNC lathe in the thread of the car? When the CNC lathe processes the thread,Because of the change of its transmission chain,In principle, as long as the speed of the spindle can be guaranteed every week,The tool can shift a pitch along the main feed shaft (mostly the z axis,Should not be restricted.But when the CNC lathe processes the thread,(1) the pitch (guide) value of the instruction in the thread processing program section,Equivalent to feed speed F represented by feed (mm/r,If the spindle speed of the machine tool is selected too high,The feed rate (mm/min) after conversion must greatly exceed the normal value;(2) the tool at the beginning/end of its displacement,It will be constrained by the lifting/lowering frequency of the servo drive system and the speed of the numerical control device,Due to the reasons that the rise/frequency reduction characteristics can not meet the processing needs,The pitch of some screw teeth may not meet the requirement
