Star SU has perfected a line of cavity/porting tools that will allow cuts from either a solid or cast core casting condition. In many cases, these multi-step tools will allow cavity machining in one pass or shot.

When machining fluid power cavities, there are several characteristics that are very critical to the performance of the hydraulic port. The most important characteristics for the cavities are controlling bore size, roundness and the finishes for these machined diameters to prevent leakage. Each of the diameters or forms machined for a given cavity on your part that are not generated correctly can damage the seals or O-rings, and also can result with the failure of the manifold/valve body.

The most accurate way to produce the cavity is by using either one or two passes with a solid carbide tool. Our latest engineered designs have replaced traditional sub-landed tools and hold extremely tight tolerances. The number of tools used to machine the cavity is determined by the diameter sizes and depths of cut. Our Engineering Department determines tooling needs at the time of the proposal.
