Conprofe Ultrasonic-Green Solution Enables Less Burrs and Lower Cost in Cervical Cage Machining
Conprofe Ultrasonic-Green Solution Enables Less Burrs and Lower Cost in Cervical Cage Machining
A cervical cage is an inter-body implant for the treatment of cervical joint diseases. As the workpiece needs to be implanted into the human body, the machining accuracy, surface quality and cleanliness of the cervical cage machined need to be strictly controlled. Otherwise, it may cause defective workpieces, or oven endanger human life.
Today, we would like to introduce an innovative solution for cervical cage machining - Conprofe Ultrasonic-Green Machining Solution. After comparison, we found the Conprofe solution can significantly improve surface quality, extend tool life, and reduce machining cost.
Challenges
The cervical cage, made from PEEK (polyetheretherketone), has a higher coefficient of thermal expansion than metal and is prone to burr and deformation during machining. Originally, the customer's used an internationally renowned 5-axis machine tools and coolant, which resulted in serious burrs, making difficult, inefficient and costly de-burring necessary. In addition, the coolant left on the workpiece need to be cleaned, increasing machining cost.
Conprofe Solution
Conprofe solution combines Conprofe Ultrasonic-Green Engraving and Milling Center UGM-500 with a Smartguy 5-Axis Rotary Table and a Supercritical Carbon Dioxide (ScCO2) Cryogenic Cooling System. The Smartguy 5-Axis Rotary Table is adopted to realize 5-axis positioning and 5-axis simultaneous machining, meeting the requirement of geometrically complicated surface machining and drilling of PEEK cervical cage. And the Supercritical Carbon Dioxide (ScCO2) Cryogenic Cooling System plays a key role in cooling and lubricating the tool, and thus extending tool life by converting the supercritical CO2 fluid into a low-temperature cooling medium of -78°C.
