Guide to Choosing the Right Turning Insert for Your Material
Learn how to select the optimal turning insert based on material type, cutting conditions, and desired surface finish.
Introduction
Selecting the right turning insert is crucial for achieving optimal machining results. The wrong insert can cause premature wear, rough surfaces, and high production costs.
Selection Factors
There are several key factors to consider:
- Workpiece material: Steel, stainless steel, cast iron, aluminum, or exotic materials require different insert grades.
- Cutting conditions: Cutting speed, feed rate, and depth of cut determine the required insert geometry.
- Setup stability: A rigid machine allows the use of inserts with smaller clearance angles.
Grade Recommendations
Tungaloy provides various grades for every need: T9225 for general steel, T9235 for interrupted cuts, and AH8015 for cast iron.
