Low-volume precision 5-axis milling depends on completing complex geometries in a single setup while maintaining batch consistency. KT’s 5-axis machining centers enable multi-surface machining in one clamping, reducing positioning errors and ensuring tight tolerances and surface quality. Once the first article is validated, process parameters are standardized and locked, allowing stable replication across small batches while minimizing setup time and delivery risk.
Detailed Description
This precision through-hole support block is a general-purpose high-strength heightening positioning part for mold fixtures, automation equipment and machine tool frames. Integrally precision milled from solid 45# steel bar, it features parallel and perpendicular finished six faces, with the central high-precision coaxial through-hole formed in one pass. With flat end face and high rigidity, it can stably withstand axial pressure and lateral loads. It can be used as equipment heightening block, frame support foot, shaft assembly positioning sleeve, mold clamping block or fixture positioning limit block, ensuring equipment installation accuracy, stress stability and overall rigidity, with excellent batch consistency.
