Why KVB’s Implant? The Reason Why We Will be Chosen
Concretely speaking, that is because of the parts of hip prosthesis we make;“Femoral Head Ball”, “Outer Cup” and “Bipolar Cup”.
We manufacture infinitely perfect sphere of which sphericity accuracy is from 0.1μ to 0.3μ. The sphere surface is infinitely polished and their surface roughness is less than Ra0.03μ. Each parts of prosthesis need to bear smoothly when legs move, and the axis of the bearing surface will be the femoral head ball. The high accuracy of the femoral head ball contributes to the longevity of the hip replacement system. KVB has the top share domestically in Japan in the area of the ball for the stainless ball valve. Accumulated spherical machining technology starting from 1964 is leveraged for the implant parts spherical machining.
