Challenges and Solutions in CNC Milling of Special Materials

Titanium Alloy Machining Challenges and Countermeasures

Shengpeng Company addresses the challenges posed by titanium alloy's poor thermal conductivity and high susceptibility to deformation by employing specialized carbide tools (WC-Co type) with high-pressure cooling at 70 bar. Combined with High Precision CNC Milling using segmented cutting (depth of cut: 0.1–0.2 mm), this advanced approach effectively controls thermal stress, achieving tolerances as tight as ±0.005 mm and surface roughness of Ra 0.8 μm—fully meeting the stringent requirements for medical and aerospace components.

Challenges and Solutions in High-Temperature Alloy Machining

Shengpeng achieves a remarkable 99.2% yield rate for high-temperature alloy cavity parts by utilizing ultra-fine-grain cutting tools, optimizing spindle speed (800–1200 rpm) and feed rate (50–100 mm/min), and leveraging vibration-resistant, high-rigidity 5-Axis CNC Milling machines. This integrated strategy ensures precision, consistency, and exceptional part quality even under extreme thermal and mechanical conditions.

Challenges and Solutions in Composite Material Machining

For composite materials such as carbon fiber, Shengpeng employs diamond-coated cutting tools and vacuum-suction fixtures, incorporating a pre-milling slotting process into its CNC milling services. This innovative method effectively suppresses delamination and chipping, maintaining scrap rates below 3% and consistently delivering high-quality results that meet the exacting standards of premium metal and composite milling applications.
