Use of External Grooving and Parting-Off Tools in CNC Turning Machines
Precision and Stability:
External grooving and parting-off tools are designed to operate with high precision. These tools
perform cutting operations accurately and consistently, even in tight spaces, ensuring the
correct shaping of the workpieces.
Application Areas:
External grooving tools are primarily used for creating grooves, threads, and various channel
profiles. Parting-off tools, on the other hand, are preferred for separating or cutting off parts.
Both types of tools are commonly used in CNC turning machines for a wide range of machining
operations.
Material Selection:
These tools are manufactured from materials resistant to wear and high temperatures, such as
hardened steel and carbide. Such materials enhance tool life while improving cutting efficiency.
Cutting Speed and Efficiency:
In CNC machines, external grooving and parting-off tools operate at high speeds and in
automated cycles, reducing machining time and increasing production efficiency. These tools
provide sharp and clean cuts with minimal vibration, contributing to superior surface quality and
process reliability.
Advantages of Internally Cooled External Grooving and Parting-Off Tools
Prevention of Excessive Heat:
Tools equipped with internal cooling systems prevent the high temperatures generated during
cutting from damaging both the tool and the workpiece. The coolant is directed precisely to the
cutting zone, reducing heat buildup on the workpiece and extending the tool’s service life.
Improved Cutting Performance
Internal cooling allows the workpiece to be machined more cleanly and smoothly during cutting
operations. Delivering coolant directly to the cutting area enhances performance, resulting in
more precise and higher-quality finishes.
Extended Tool Life:
Properly directed coolant flow minimizes tool wear and degradation. This enables longer
uninterrupted machining periods and reduces the frequency of tool changes, thereby lowering
overall production costs.
High Efficiency:
Internal cooling significantly improves machining efficiency. By preventing tools from
overheating, it enables higher cutting speeds and greater cutting capacity. This leads to
substantial time savings in production processes.
