Polishing fixture for brass faucet components — machined in three phases with ENCY CAM

An Italian job-shop, Lavorazioni Meccaniche CS, used ENCY CAM to program a three-stage 3-axis machining sequence that produces a custom polishing fixture (forma di pulitura) for the surface finishing of brass faucet components — rosettes, spouts, cartridge caps and other decorative bathroom hardware. The fixture is turned from a solid aluminum blank and machined complete in three phases, from raw stock to a finished, ready-to-use tool.

Phase 1 — Facing (spianatura).
The first operation flattens the top of the cylindrical aluminum blank clamped to the machine table with step-block strap clamps and a custom locating collar. This reference face becomes the datum for every downstream operation.

Phase 2 — O-ring seat profiling (sedi gomma).
A small-diameter finishing tool cuts the precise O-ring seats that will grip the faucet parts during polishing. Fine chips and flood water-soluble coolant confirm a light finishing pass — the profile is programmed directly from the CAD model in ENCY CAM to guarantee concentricity with the axis of the fixture.

Phase 3 — Drilling and completion.
The final pass drills the deep passages through the fixture body, completing the polishing form. From CAD model to production-ready tool, the whole sequence is programmed in a single ENCY CAM setup, giving the shop the repeatability and dimensional accuracy needed for a uniform mirror finish on every faucet component the fixture will hold.
