In the precisiondriven world of CNC machining, the Heat Affected Zone (HAZ) presents a significant challenge. The HAZ is the area of base material, typically metal, that has not been melted but has had its microstructure and properties altered by the intense heat generated during machining processes like milling and turning. Unmanaged HAZ can lead to a host of quality issues, including material softening, hardening, residual stresses, microcracking, and dimensional inaccuracies in the final part. For industries ranging from aerospace to medical devices, controlling the HAZ is not just a recommendation—it's a critical requirement for part performance and longevity.

Using sharp, geometrically optimized tools with specialized coatings like Titanium Aluminum Nitride (TiAlN) reduces friction and heat generation. Furthermore, implementing highperformance machining strategies is crucial. This includes utilizing higher cutting speeds with reduced depths of cut, which allows heat to be carried away with the chip rather than being conducted into the workpiece. A robust and optimized coolant strategy is equally vital. Whether through highpressure flood coolant or throughtool coolant delivery, the goal is to effectively dissipate heat from the cutting zone, minimizing thermal transfer to the part.
