Processing products
Workpiece material: titanium alloy TC4 (Grade 5)
Processing features: precision milling + nail hole processing (hole diameter 1.5-4mm)
Key indicators: biocompatibility ASTM F136 standard, corrosion resistance ISO 5832-3
Processing background and industry pain points
A. Medical implant industry needs
As the core component of dental/orthopedic implants, titanium alloy Malone bridges must meet the following requirements at the same time:
Mechanical properties: tensile strength ≥895MPa, elastic modulus 110GPa
Surface integrity: Ra≤0.4μm to avoid tissue irritation
Assembly accuracy: the clearance between nail hole and implant ≤15μm
B. Fatal defects of traditional processing
Low efficiency: ordinary CNC milling feed speed is limited to less than 50mm/min
Surface loss of control: cutting heat causes surface roughness fluctuations (Ra0.6-1.2μm)
Burr disaster: The burr height of the hole exceeds 80μm, and manual deburring accounts for 35% of the cost
MID Solutions: Ultrasonic green five-axis precision milling system
Vertical five-axis ultrasonic machining center: 0.5μm interpolation accuracy, supporting 0-90° multi-directional milling
20kHz ultrasonic vibration cutting: Reduce cutting temperature to below 120℃ (conventional processing reaches 600℃)
Adaptive tool path planning: Dynamically adjust cutting parameters to avoid material elastic recovery
Breakthrough advantages in processing
Super mirror effect: The surface roughness is stable at Ra0.2μm (40% better than ISO 2017 standard)
Zero post-processing: The burr height of the nail hole outlet is less than 5μm, which directly meets the assembly requirements
Efficiency revolution: The milling feed speed is increased to 120mm/min, and the single-piece working time is shortened by 55%
