Indexable Turning Tools
Indexable turning tools are cutting tools used in metalworking and machining processes. They are commonly used in lathes, CNC (Computer Numerical Control) turning machines, and other machining equipment. The term "indexable" refers to the fact that these tools have replaceable cutting inserts that can be indexed or rotated to present a fresh cutting edge when one becomes dull or worn.
Key features of indexable turning tools:
-
Replaceable Inserts: The cutting edge of the tool is made up of a separate insert, which is usually made of a hard cutting material like carbide or ceramic. When the cutting edge becomes dull or damaged, the insert can be replaced rather than sharpening the entire tool. This makes tool changes quick and efficient.
-
Multiple Cutting Edges: Indexable inserts often have multiple cutting edges, allowing for extended tool life. As one edge wears out, the insert can be rotated or flipped to expose a fresh cutting edge.
-
Secured by Clamping Mechanism: The indexable inserts are secured to the tool body using a clamping mechanism. This ensures stability during cutting operations and minimizes any movement that could affect precision.
-
Various Shapes and Configurations: Indexable turning tools come in a variety of shapes and configurations to accommodate different types of turning operations, such as roughing, finishing, threading, grooving, and facing.
-
Applicability to CNC Machines: The use of indexable turning tools is particularly popular in CNC machining due to the ease of tool changes and the ability to program tool paths for different operations.
-
Time and Cost Savings: Since only the inserts need replacement, indexable turning tools offer cost savings over traditional solid tools that require complete reshaping or grinding when the cutting edge becomes dull. Additionally, reduced downtime for tool changes increases overall productivity.
