Vibration Check Of PCD&PCBN Tool Grinding Machine


2023-05-19


When grinding a precision tool grinder, the vibration of the grinder directly affects the effect of mold processing. This may cause ripples that affect the surface finish. If it is precision molding grinding, making plug-in connector molds, cutting grooves, etc.. The machine vibration can not trim the grinding wheel at all, because sometimes the grinding wheel needs to be trimmed to 0.1-0.13mm thickness, the grinding wheel is almost transparent. If the grinding machine is slightly when the vibration is unstable, the grinding wheel will burst. Let's talk about the aspects of the vibration of the 2-axis PCD&PCBN tool grinding machine.

Vibration check of PCD&PCBN tool grinding machine

1. First, check the horizon. It is often said that the building is stable and stable. The same is true for the machine tool. If the level of the anchor screw is not adjusted, it will cause the machine to resonate. Because sometimes the ground level of the processing site is not very good, it is necessary to adjust the horizontal screw to make the machine reach an uneven height. First, we must check whether each screw of the foot is put into place in the floor mat. Before and after the level is used, the left and right sides are horizontal and the screws are locked. 2. If the above actions are carried out, the vibration is still not eliminated. We should check whether the ground floor space is empty if the ground is terrazzo or the floorboard is relatively strong. If it is cement level, the ground will be very weak. Resonance, how to deal with this situation? Don't worry, go to the rubber hardware store to buy a few black rubber pads, the thickness is about 6-10 mm, the size is 10 cm and the size of the floor mat is slightly larger. Loosen the anchor screw and put the rubber pad on the horizontal foot. Under the pad, you can play a large shock absorption function. 3. If the above action is taken and the vibration is still not eliminated, we will check the problem of the grinding machine sanding wheel and the grinding wheel fixing flange. The first is the grinding wheel. Because the quality of the grinding wheel on the market is uneven, there are two factors that affect the vibration of the grinding wheel: First, the particle size of the grinding wheel is not uniform, and the center of gravity is unstable when it is rotated; the second is that the inner hole is not too large. For example, our grinding machine flange hole diameter is 31.75, and if the grinding wheel is 32, it will jump up and down to cause a vibration when it is installed. Therefore, we must ask the specifications when buying the grinding wheel. I suggest you buy a little bit, and the difference is good. The grinding wheel affects the processing effect. Secondly, cracking and explosion is dangerous during the processing of grinding. The poor balance of the grinding wheel of the third is seriously affecting the life of the grinding spindle. Then the grinding wheel fixed flange, lift the flange, everyone will think of the balance of efficiency. In fact, the flange of the small precision hand grinder is not to be balanced, the premise is that you must use the imported precision flange. The general new flange buys it back, there are three small balance blocks on it, you take it off, the flange is directly mounted on the grinding wheel, and then the knife is repaired. The grinding wheel is naturally balanced. Buy more flanges and install different sizes of grinding wheels. Save time and save time when you use it next time. Going back to the original question, if there is vibration, it may be the above reason. Try another wheel, or if the flange is not balanced, then load the balance block. Then remove the balance block and install it. If not, change the new flange. Try, the general problem will be solved. 4. is impossible to place a machine with large vibration such as a punching machine or lathe near the same working site. It is easy to cause resonance. How to judge it is very simple. You only need to stop the grinding machine and start the punch or lathe. It is affected by the vibration or the hand feeling of touching the grinding machine. The treatment method is to separate the workshop. 5. If the above series of actions still fail to eliminate the tool grinder vibration, it may not be the scope you can handle. It may be that the grinding machine spindle takes longer to vibrate itself. Beijing Demina Precision Machinery co., ltd specializing in the production of BT-150H tool grinder.
