Stainless steel grades including 303, 304, and 316 require more conservative parameters but produce excellent results with proper tooling selection. Titanium and high-temperature alloys demand specialized approaches but can be successfully machined using Haas machines equipped with high-pressure coolant systems and rigid tapping capabilities. Engineering plastics such as PEEK, Delrin, and Ultem achieve superior surface finishes when machined with sharp, positive-rake tools at elevated spindle speeds. The following table illustrates recommended machining parameters for common materials:

Achieving Precision with Haas CNC Turned Parts

Designing components for CNC turning requires careful consideration of multiple factors to ensure manufacturability and precision. Critical design elements include proper feature accessibility, appropriate tolerance specifications, and suitable material selection. For Haas , designers should maintain wall thicknesses exceeding 1mm for metallic components and 2mm for plastic parts to prevent deformation during machining.
