Three elements
Base material First of all, manufacturing of order-made soft jaws start choosing the best base material which is suited to processing parts. We have our know-how to choose the best base material from abundant records in the past, considering varieties of terms such as the material, degree of hardness and shapes.
Cutting If you make a mistake in centering, the shape of quarter sector become unbalance and it has influence on vibration of cutting, shaking and finishing surface roughness. This shape processing skill is also Teknia's strong point.
