Yaxis vibration

· Yaxis vibration. i recently purchased an early 1990's Kiwa Excel 810 vertical mill. when i was checking it out i pushed hard on the table in the Y axis to check for backlash on an indior and it started to vibrate (low humming noise). It stopped once i moved the y axis with the handwheel. I saw the machine cut various times and never saw ...

Milling machine vibration

· Milling machine vibration. I have a Sharp LC 1 1/2 Mill 9 x42 (Bridgeport J clone) seems to be in reasonable shape, backlash x=22 y=h18. When Conv milling in X or Y on 1018 steel with rpm a little slow due to dry cutting with the spindle fully retracted and locked, I can feel each tooth cut into the work through the hand crank (Not chatter).

How To Reduce Chatter Vibration In CNC Machining

· · Chatter is a problem that every CNC machine operator must deal with from time to time. Machining vibration is a common problem in CNC manufacturing. Milling, turning or drilling will all cause parts to suffer this torture. It affects the quality and efficiency of processing, will cause the finish of the parts to decrease, and will damage and significantly shorten the life of the end mill.

Chatter in Machining: Milling Lathe Vibration [ Easy Guide ]

Chatter is a resonant vibration in the machine or workpiece. It can become quite violent and generate a distinctive loud noise. It's almost never a good idea to keep machine in the face of strong chatter–chatter in machining is very bad for your tool life, interferes with the accuracy of the machining operation, and will shorten the life of your machine too.

Why vibration is the enemy of the machining process ...

Machine vibration, if left uncontrolled, can seriously reduce machining efficiency. The ways in which machining can be hampered due to chatter are listed below. Reduced machine life – Unchecked chatter can place undue stress on machine components, which can cause the spindle and key components creating the various axes of motion to wear out faster than normal.
