How to Prevent Vibration when Turning Thin-walled Workpiece？
In the turning process of thin-walled workpieces, due to the poor rigidity of the workpiece, vibration often occurs; especially when turning stainless steel and heat-resistant alloys, the vibration is more prominent, the surface roughness of the workpiece is extremely poor, and the tool life is shortened. There are three simple methods for anti-vibration when we use carbide turning inserts turning thin-walled workpieces are introduced below.
- When turning the outer circle of a stainless steel hollow slender pipe workpiece, the hole can be filled with sawdust and plugged tightly, and then plug cloth bakelite plugs at both ends of the workpiece at the same time, and then replace the support claws on the CNC tool holder. After correcting the required arc, the stainless steel hollow slender rod can be turned. This simple method can effectively prevent the hollow slender rod from vibration and deformation during cutting.
- When turning the inner hole of a heat-resistant (high nickel-chromium) alloy thin-walled workpiece, due to the poor rigidity of the workpiece and the slender tool shaft, severe resonance occurs during the cutting process, which can easily damage the tool and produce waste. If rubber strips, sponges and other shock-absorbing materials are wrapped around the outer circle of the workpiece, the shockproof effect can be effectively achieved.
- When turning the outer circle of heat-resistant alloy thin-walled sleeve workpieces, due to the comprehensive factors such as the high cutting resistance of heat-resistant alloy, it is easy to produce vibration and deformation during cutting. If you use rubber or cotton thread in the workpiece hole, and then use the clamping method of the two ends to hold the clamp to effectively prevent the vibration and workpiece deformation in the cutting process, and can process high-quality thin-walled sleeve workpieces.
The above method is the experience sharing by an experienced lathe worker in UKO. Do you have any other good solutions for turning and milling? Welcome to exchange experience and views!
