The Use of Coolant Through Tooling in CNC

In the competitive world of precision CNC machining, maximizing efficiency and tool life is paramount. One advanced technology that delivers on both fronts is ThroughTool Coolant (TTC), also known as highpressure coolant through the spindle. This method is a significant upgrade over traditional flood cooling and is a cornerstone of modern, highperformance machining, especially in demanding industries like aerospace and medical device manufacturing.

Traditional flood coolant often struggles to reach the critical cutting edge during deephole drilling or intricate milling operations. This leads to excessive heat buildup, which is the primary enemy of cutting tools. Heat accelerates tool wear, causes premature failure, and can compromise the metallurgical integrity of the workpiece. In contrast, TTC systems pump highpressure coolant directly through internal channels in the tool holder and the cutting tool itself. This delivers a precise, targeted stream of coolant exactly where it's needed most: the interface between the tool and the workpiece.

The benefits for your production are substantial. First, it dramatically extends tool life. By effectively removing heat, tools last longer, reducing both downtime for changes and overall tooling costs. Second, it significantly improves chip evacuation. The highpressure coolant breaks chips into smaller, more manageable pieces and flushes them out of deep cavities, preventing chip recutting, which can damage the workpiece and the tool. This results in superior surface finishes and tighter tolerances. Third, TTC enables higher machining parameters. With effective heat management, you can safely increase feed rates and cutting speeds, slashing cycle times and boosting overall throughput.
