The machining center let out a screech
Thread Content
At the factory, I saw workers machining deep-hole steel parts (forgings), with a cutting depth of 100 and a feed rate of 2. The office is 50 meters away from the equipment; there are two doors there, and it’s still quite noisy. As for the workshop, it’s even noisier. What is the reason for this? Is it the insufficient power of the main spindle? The vibration seems quite strong; will it affect the precision of the bed?
The tool shank lacks rigidity, resulting in vibration, which creates an amplifying effect on deep-hole parts. It has little impact on the precision of the lathe.
It’s not necessarily caused by insufficient rigidity of the blade shaft; it also depends on the specific material. If the co-vibration is too severe or lasts for too long, it still has a significant impact on the precision of the machine tool. For example, loose foundations or loose fasteners.
The rigidity of both the equipment and the cutting tools can lead to this situation. It also depends greatly on whether the cutting edge of the tool is severely worn, whether sufficient cooling is provided, and whether the cutting parameters are appropriately chosen. A comprehensive consideration of the material of the part is necessary; the precision of the machine tool is also affected by these factors: loveliness:
Issues with the rigidity of the equipment and tools, or equipment resonance
Since it was a screeching sound, I think it’s due to worn cutting tools. The tool is worn out too severely. It can also be caused by a problem with the cooling equipment, which leads to overheating of the tool and thus this issue arises. Another possibility is that there is a problem with the circuit components – they have aged!
“The cutting depth is 100, and the feed rate is 2 inches – quite aggressive; it’s also made of steel forgings
Poorly sharpened tools, inadequate lubrication, insufficient cooling, loose anchor bolts, excessive feed rate, and low stiffness of the tool holder can all cause noise and tool vibration.
