Common Materials: Superalloys, Titanium Alloys
Tool Types: Ball End Mills, Tapered Ball End Mills, Indexable Milling Cutters
Machining Challenges: Complex free-form surfaces, heat resistance, poor machinability, extremely high surface finish requirements
Da Xiongdi Tooling Solutions:
• Use 5-axis milling cutters for machining blade contours
• Use AlTiN/nano-coated tools to withstand oxidation and high temperatures
• Use tapered ball-nose cutters, which are well-suited for deep curved surfaces, improving rigidity and reducing vibration
• Use ball-nose cutters for finishing curved surfaces
Common Materials: Titanium alloy, titanium alloy, carbon-carbon composite
Tool Types: High-helix end mills, indexable end mills, PCD diamond end mills
Machining Challenges: Poor heat resistance, easy deformation, extremely high hardness, prone to chipping
Big Brother Tooling Solutions:
• Carbide end mills with high-speed cutting
• Layered small feed control
• Dust extraction system
• Rigid toolholder design to reduce tool deflection in deep cavity machining
Common Materials: High-feed end mills, corn milling cutters, large-diameter cutting tools
Machining Challenges: Thin-walled parts are prone to deformation, wear is extremely rapid, and chip removal is challenging.
Big Brother Tooling Solution:
• Uses DLC coating for extremely low friction coefficient
• Employs mirror-polished groove design to improve chip removal
• Uses special anti-vibration geometry to ensure a smooth surface finish on thin-walled parts
• Uses large-diameter cutting tools for rapid roughing, reducing vibration.
AS9100 and NADCAP certifications; raw material traceability and complete heat treatment records.
High-temperature resistant nanocomposite coating: Utilizes ultra-low friction PCD/CVD coating. Ultra-low friction PCD/CVD coating: Utilizes diamond coating and PCD cutting tools.
It can solve the challenges of machining difficult-to-machine materials such as titanium alloys, high-temperature alloys, and aerospace-grade aluminum alloys, and can provide solutions for customized non-standard aerospace parts structures.
We adhere to international industrial standards in our production and testing systems, using mainstream international high-precision equipment such as high-precision CNC tool grinders. We uphold global quality systems.
Standard products: 5–7 days; non-standard products customized according to drawings: 7–15 days.
Standard: Cutting speed recommended at 40-70 m/min，High-efficiency cycloidal milling: Recommended cutting speed is 100 - 160 m/min
Process: Storage, Cleaning, Testing, Grinding, Cooling
Under proper operation, the tool will not easily break, but the following points should be noted: appropriate cutting parameters, correct clamping system, and avoid overload machining.
