How to deal with the abnormal bumps when the CNC cutting machine is used?

　　The application field of CNC cutting machine is relatively wide, and it is used more in many large factories. It can play a good role in processing, and can deal with some abnormal phenomena in time in the later use, such as some bumps. Next, I will introduce how to deal with this kind of abnormality in detail.

　　1. Guide gap adjustment

　　 The guide gap refers to the two guides of the two guide rollers and the front guide The gap between the sides.

There is a guiding gap between the horizontal carriage (or torch carriage) and the horizontal front rail (or beam), and the guiding gap between the longitudinal carriage and the longitudinal front rail.

Excessive guide clearance will affect the verticality and movement accuracy. Gently turn the guide rail rollers on both sides of the front guide rail by hand, and you can feel the size of the guide rail gap.

　　 By rotating the eccentric shaft, the guide gap can be adjusted. When adjusting, gently rotate the eccentric shaft to avoid pressing the guide rollers on the side of the track. When you feel the guide rollers on the side of the track, reverse the angle to form a small gap and lock the eccentric shaft.

Because the longitudinal carriage has two pairs of idlers relative to the longitudinal front rail, there is also a case for adjusting the eccentric shaft. The guiding structure of the horizontal front rail using the horizontal sliding frame is similar to the guiding structure of the vertical front rail using the vertical sliding frame, and the adjustment method is also the same.

　　2. Adjust the drive gap

　　 The stepper motor and servo motor of the CNC cutting machine are all realized by gear and rack and pinion transmission, and the rack is fixed on the longitudinal front guide rail and On the horizontal front rail.

　　The small gear in the gearbox is fixed on the output shaft of the stepper motor, and the big gear is positioned on the gearbox through the shaft.

Therefore, the adjustment of the transmission gap of the gears in the transmission box can loosen the fixing of the stepping motor to the transmission box, as long as the stepping motor and the small gear are close together in the direction of the big gear and then tightened. The purpose is to eliminate the gap during adjustment, but the gears and gears should not be too tight.

　　 The above is the specific aspects of processing after the abnormal bump occurs when the CNC cutting machine is used. When processing, you need to pay attention to the adjustment gap, and its size needs to be strictly controlled. Control, so as to facilitate its later use. If such problems occur in use, they need to be dealt with in time.
