The Use of Coolant Through Tooling in CNC Machining

In the competitive world of precision CNC machining, achieving superior part quality, maximizing tool life, and optimizing cycle times are paramount. One advanced technology that delivers on all these fronts is ThroughTool Coolant (TTC), also known as HighPressure Coolant. For businesses seeking a reliable, highperformance manufacturing partner, understanding and utilizing this technology is a significant differentiator.

Traditional flood coolant methods effectively remove heat and chips from the external machining area. However, they often fail to reach the critical point of contact between the tool's cutting edge and the workpiece, especially in deep cavities or when using longreach tools. This leads to accelerated tool wear, poor surface finishes, and potential work hardening of the material.

ThroughTool Coolant systems overcome these limitations by delivering highpressure coolant directly through internal channels in the tool holder and the cutting tool itself. This targeted approach offers substantial benefits:

1. Dramatically Improved Tool Life: By efficiently evacuating heat and lubricating the cutting edge at the source, TTC significantly reduces thermal shock and abrasive wear. This can extend tool life by several times, directly reducing consumable costs and machine downtime for tool changes.

2. Enhanced Chip Evacuation: The highpressure stream effectively breaks chips into manageable pieces and flushes them out of deep holes and pockets. This prevents chip recutting, which can damage the tool and the finished part, and allows for more aggressive machining parameters.

3. Superior Surface Finish and Precision: Effective heat management minimizes thermal expansion of both the tool and workpiece, ensuring consistent dimensional accuracy and a higherquality surface finish, often eliminating the need for secondary operations.

4. Increased Productivity: With better heat and chip control, machinists can safely increase feed rates and cutting speeds, significantly reducing cycle times and boosting overall throughput.



At our onestopshop for CNCmachined components, we have integrated advanced TTC systems across our machining centers. This capability is particularly advantageous when machining challenging materials like titanium, Inconel, and stainless steel, and for complex operations such as deephole drilling and tapping. It is a core part of our commitment to delivering precision parts with faster lead times and exceptional value.

By partnering with a supplier that leverages ThroughTool Coolant technology, you are not just purchasing a part; you are investing in a more efficient, reliable, and costeffective manufacturing process that drives your project's success.
