automated transfer machineduring the production process, how to solve? Lathe in the machine, parts appear vibration, dry machine plus friends have met more or less, this situation can be described as basically everywhere in the factory.

I believe that when doing fine cars, they often encounter that the car does not have a beautiful appearance, and it is necessary to use fine sandpaper or oil stone to quietly polish it. Especially after the high precision requirements need to be electroplated, then you need to be very careful, otherwise it is easy to constitute waste products.

Because there are too many factors that can make the product appear vibration, we can start from these aspects of the investigation, and according to their own factory conditions, detailed analysis.

First of all, how to determine the seismic tool in the production process of automated transfer machine? Whether there is a "vibration grain", the usual rule is: there is a horizontal grain, which looks like a spiral grain with a relatively large distance.

1, it is necessary to understand whether the workpiece is a vibration after processing, or a vibration after secondary finishing.

2, the machine is not a collision, if the collision, it is easy to appear Z axis screw, spindle effect, this situation will appear vibration.

3, take a look at whether the machine speed can belong to a reasonable range is relatively large, and at the same time, the sequence of the feed into the feed to try. (The machine tool speed is firmly large, resulting in uneven feed speed, acceleration and deceleration from time to time, and the machine tool private service unit and the actuator are easy to form ripples if the accuracy is not high enough)

The ordinary machine tool panel display is the speed reflected by the practice spindle encoder, see if the speed can be determined when it is obligated, the most direct is to directly change the feed component feed, if the effect is improved then it is generally the encoder defect or frequency converter defect.

4, the rigidity of the machining center system driver does not match

5, the workpiece itself or the fixed rigidity of the workpiece, like some smaller, thinner parts due to the lack of rigidity of its own, or due to the shape of the workpiece, by the use of reasonable clamping fixture to suspend sufficient fixed.

6, Z axis screw support bearing, back cap loose is easy to cause vibration.

7, the knife has no effect, whether the arc of the tip is too large, the blade is too wide is easy to appear horizontal, directly change the hand sharpening knife, can reduce the vibration, or the tip of the knife grinding out the transition blade.

8, the rigidity and dynamic balance of the external reason is relative to the rotating axis, the quality of the external elements is unbalanced, and the attack of the vibration grain is caused by the effect of the unbalanced centripetal force during rotation. Especially in high-speed processing, the dynamic balance of things has a great impact.

9. The selection of cutting parameters includes cutting speed, feed, feed amount and cooling method.

10. The guide rail of the machining center machine tool is loose
