What we don't see when turning HTA at a microscopic level is that a heat pocket is being created between the cutting edge and the chip being formed. This heat pocket is preventing coolant from targeting the cutting edge. What HPC does is break through the heat pocket and get coolant to where it needs to be. External flood coolant will not be able to break through the heat pocket, which will cause the coolant to evaporate at these cutting temperatures. With pinpoint coolant placement, we can then see improvements to chip control, extended insert life, and increased cutting parameters.
