Polyethylene bone pads are orthopedic implants made of high-density polyethylene (HDPE) or ultra-high molecular weight polyethylene (UHMW-PE), which have excellent wear resistance, low friction coefficient and excellent biocompatibility. This material exhibits strong chemical corrosion resistance and low water absorption in the human body, which can effectively reduce wear and inflammatory response in joint replacement and extend the service life of implants. Polyethylene bone pads are widely used in artificial joint replacement surgeries such as hip joints, knee joints and shoulder joints, and are an indispensable key material in the field of modern orthopedics.
Unrivaled Sharpness:The single-crystal diamond edge ensures minimal cutting forces, reducing deformation and achieving precise cuts with mirror-like finishes.
Outstanding Wear Resistance:The inherent hardness of monocrystalline diamond enables extended tool life, even in continuous operations.
Low Adhesion:MCD tools significantly minimize material adhesion and chip buildup, ensuring a clean and smooth machining process.
Optimized for Soft Materials:Specifically engineered for UHMWPE, these tools maintain high performance without compromising the structural integrity of the workpiece.
Superior Heat Management:Reduced friction at the cutting interface lowers thermal buildup, preventing material softening and enhancing
Precision machining of polyethylene tibial inserts for artificial knee joints.
High-tolerance operations in medical device manufacturing.
Achieving superior surface finishes for biocompatible components.
