Turning Insert FAQ

During the turning process, you may encounter some common problems when using inserts, which may affect the quality and efficiency of the machining.

Over time, inserts wear out. This results in reduced surface quality, increased cutting forces and slower machining speeds.

Broken inserts: Inserts can break due to excessive cutting loads or design flaws. This can lead to unplanned downtime and production disruptions.

Cutting temperatures that are too high: Elevated cutting temperatures may anneal the blade, reduce its hardness, or cause the blade coating to peel off. This affects cutting performance and insert life.

Cutting Vibration: Cutting vibration can result in poor surface quality, shortened tool life, or even damage to the workpiece or machine tool. This is usually related to unstable cutting conditions or material non-uniformity.

Insert Buildup: When cutting metal, chips can build up on the insert, which can affect the quality of the cut. Cutting lubrication and chip evacuation are key to preventing this problem.

Poor surface quality: If the insert is not selected correctly, the cutting speed is too high, or the blade is severely worn, it may result in poor surface quality of the workpiece, such as burrs, dents or blemishes.

Unstable cutting conditions: Inserts may work under unstable cutting conditions, resulting in drastic changes in cutting forces, affecting machining quality and tool life.

Improper insert selection: Selecting an insert type or parameters that are not suitable for a specific machining task may result in reduced performance or blade damage.

Cutting lubrication issues: Insufficient cutting lubrication or coolant quality issues may prevent cutting heat from being dissipated effectively, affecting tool performance.

Cutting instability: Under certain conditions, unstable oscillation or resonance may occur in the cutting process, which requires careful parameter settings to avoid.
