Sun's Compound Angle Drilling
Sun Hydraulics has always employed compound angle drilling in its manifold manufacturing. By incorporating compound angle holes, a number of benefits are realized, including:
- Manifolds that are physically smaller
- Minimum "construction" drillings with fewer plugs
- Minimum potential leakage points
- Unique sandwich body configurations
Below is a comparison between two different manifold designs. The manifold on the left was designed with 3 axis straight hole drilling. The manifold on the right is typical of Sun manifolds and was designed with 5 axis compound angle drilling.
Incorporation of compound angles in manifold design is governed by good design practice. Sun follows long-established principles that define minimum distances between ports, passageways, and manifold surfaces to ensure integrity of the manifold at its rated pressure.
